GENERAL INFORM ATI ON

WATTrouter Mx is a programmable controller to optimize self-consumption of energy produced by photovoltaic or wind power plant (hereinafter referred to as PV-plant). It is a smart home energy management system. After correct installation and configuration, the controller perfectly optimizes self-consumption of energy produced by your PV-plant. WATTrouter Mx consists of a current sensing module and the regulator itself.

WATTrouter Mx offers the following functionalities:

 Three-phase indirect current measurement.  Single phase detection of voltage necessary to determine the power direction in phase L1, for other

phases it is determined by software.

 Evaluation of active power outputs in individual phases, necessary to determine the surplus of

produced electric power.

 Regulation based on the sum of power outputs (summary surplus) from all three phases or based on

surplus in each phase.

 Switching for up to 8 outputs (2 relays and 6 external solid state relays SSR) based on configured

priorities.

 Optimal use of surplus energy produced by PV-plant on SSR outputs through the application of

proportional synchronous regulation of resistive loads, compliant to European standards EN 61000-3-2 and EN 61000-3-3. This regulation modulates connected load's power exactly according to the available surplus energy.

 Very short average dynamic response of the controller (up to 10 s)  Optional CombiWATT function used for switching loads under a combined mode where energy is

taken both from PV-plant and public grid (especially suitable for water heating and also for swimming pool filtering system).

 Input for low tariff signal (nightly low price electricity) for CombiWATT. This is for households where

double tariff rates will apply.

 4 multi-purpose ANDI inputs for connection of external current transformers, impulse outputs of

external energy meters, and analog temperature sensors of type NTC or PT1000.

 DQ input to connect up to 4 digital temperature sensors of type DS18x20.  Separated current sensing module and regulator for easy installation into existing household wiring.  WATTconfig software designed for Microsoft Windows, Linux and MAC OS X, provides comfortable

controller configuration and monitoring via USB, Ethernet or RS485 interfaces.

 Integrated web interface allows comfortable controller configuration and monitoring using regular

Internet browser.

 Real-time module backed with a lithium battery for advanced management of outputs and

CombiWATT function.

 Daily, weekly, monthly and annual statistics.  Integrated MicroSD card.  Firmware update.

DESCR IPTION OF BASIC FUN CTI ON

The current sensing module measures electric current in real time and on all phases. The regulator evaluates the measured electric currents and if it determines the available surplus energy produced by the PV-plant, it will switch on connected loads according to adjustable priorities, while constantly trying to maintain zero energy flow through the current sensing module, the so called "virtual zero" (the sum of active power outputs on all three phases = 0) or optionally, on each phase separately, so called "phase zero".

Switching according to priorities is done in the following way:

By default (during night), all loads are turned off. If surplus energy generated by PV-plant is determined in the morning, the output with the first (highest) priority is switched on.

The switching time is different according to selected output function.

 SSR/PWM outputs (proportional outputs) are switched on almost immediately after surplus energy is

detected and the controller is gradually (synchronous control or PWM modulation) maintaining "virtual zero" or "phase zero", according to the control settings.

 Relay outputs are switched on only if the surplus energy exceeds the preset load‘s nominal power.

Alternatively, relay outputs may be operated in "prepend" mode if there is sufficient power at any proportional output with nearest higher priority. This allows for maximum utilization of the produced surplus power even for relay outputs - refer to the "Prepend before SSRs" function.

When load with 1st priority is switched on (for proportional output it means switching on the maximum power), the system waits until the power output of PV-plant increases again (beginning of dawn). If electric production is determined even when this load is switched on, load with second priority in the same mode is switched on as well.

If the power output of PV-plant is still increasing, additional connected loads are switched on in the same mode.

If the power output of the PV-plant decreases, or if another load - not connected to the WATTrouter device is switched on, the switched (active) outputs are disconnected - again according to preset priorities but in reverse order (the load with lower priority is disconnected first).

For relay outputs there may be set a minimum switching time. If, simultaneously with a relay output the proportional output with higher priority is switched on, and the available surplus energy is reduced, then this proportional output will reduce the power output of the of the load (even down to zero) in order to maintain virtual zero or phase zero on the current sensing module, if possible.

Except for the situation specified in the paragraph above, the controller never violates the established priorities.

The above specified principle applies only to standard connection of the current sensing module, connected right behind the facility’s main energy meter, so the WATTrouter device uses only the actual PV-plant surpluses (recommended settings). However, WATTrouter controller is versatile device and can be connected according to your needs. For example, you can place the current sensing module just next to the PV inverter and then you can maintain the virtual or phase zero on that line.

The above specified basic control mode may be combined with another mode of output switching, provided that low tariff signal (double tariff rate) is available (CombiWATT mode), or with switching based on preset time conditions (time schedules).

When you receive your package, inspect the packaging unit for damages. After opening your package, inspect the regulator and the current sensing module for damages. Do not fit the regulator or the current sensing module if you see signs of mechanical damages!

Always have the regulator and the current sensing module fitted by a person with the necessary electrical certificate and qualifications. It is necessary that you read this manual thoroughly and observe all safety warnings and requirements specified herein.

The regulator and the current sensing module must be fitted in a dry room without excessive dust level. The room must be protected from direct sunlight and the ambient temperature must be maintained within the range mentioned in chapter Technical specifications. Do not place the regulator or other electronic components of this system near flammable objects!

When power SSRs are connected to SSR outputs, it is absolutely necessary to fit these into a distribution box equipped with adequate heat dissipation system (with ventilation grid or vents)!

Make sure that unauthorized persons, mainly children, cannot access the location where the controller is fitted. There is a serious risk of electric shock!

Only connect outputs of the controller to electrical loads which have been designed for this operation mode and for which the manufacturer does not explicitly prohibit connection via switching element!

The manufacturer is not liable for any damages occurred due to improper fitting or operation of the device! The owner is fully responsible for operation of the entire system.

FI TTING THE DEVICE

WATTrouter Mx regulator may be fitted in a regular electrical distribution box onto a 35 mm DIN rail or attached to a wall using 2 screws with round or countersink head and with diameter up to 6 mm.

WATTrouter Mx current sensing module may be fitted in a regular electrical distribution box onto a 35 mm DIN rail.

Measuring inputs of the current sensing module may be connected as single, double, or triple-phase connections.

The recommended maximum distance of the current sensing module and the regulator is 2 meters. Bigger distance is acceptable, but it will slightly affect the measuring accuracy.

If CYKY or other thick and hard cables cannot pass through current transformers easily, use flexible cables to extend the existing connections. When fitting the current sensing module do not press hard on it. You may damage the module.

Tip: Individual phase wires may pass through the current sensing module from either direction. The direction of currents may be configured in the control software.

To connect power supply to the regulator (L1 and N) use wires with a minimum cross-section of 0.5 mm2, for example CYKY 1.5.

To connect loads to the relay outputs use wires with adequate cross-section corresponding with the power ratings of the connected loads.

To connect loads to the power SSRs again use wires with adequate cross-section corresponding with the power ratings of the connected loads.

To interconnect the current sensing module and regulator (inputs Y and ILx) use 4-wire cable with cross-section from 0.5 to 1.5 mm2. If these wires are longer than 2m or are placed in a cable tray together with other power cables/wires, we recommend using a shielded cable. Similar recommendation applies for connecting external current transformers to the ANDI inputs.

To interconnect power SSR control inputs and/or 0-10VDC control signals with SSR outputs use wires with cross-section from 0.5 to 1.5 mm2. If these wires are longer than 2m or are placed in a cable tray together with other power cables/wires, we recommend using a shielded cable.

To interconnect S0 impulse signals from external energy meters with ANDI inputs use 2-wire cable with crosssection from 0.5 to 1.5 mm2, connected between GND and respective ANDI terminal. If these wires are longer than 2m or are placed in a cable tray together with other power cables/wires, we recommend using a shielded cable.

To interconnect analog temperature sensors with ANDI inputs use 2-wire shielded cable with cross-section from 0.5 to 1 mm2, connected between GND and respective ANDI terminal.

To interconnect digital temperature sensors of type DS18x20 to DQ bus use 3-wire shielded cable with crosssection from 0.5 to 1 mm2, connected between GND (ground), +5V (power supply) and DQ terminal (data bus). When connecting other sensors to the DQ data bus always connect shielding. Total length of the bus including all branches should not exceed 50m.

Connect shielding of all shielded cables to the GND terminal as close as possible to the regulator.

If you use shielded cables then use for each type of signal a standalone shielded cable, i.e. do not mix signals from analog and digital sensors in one cable, especially when making the cables longer. There might be crosstalk which will decrease measurement accuracy.

Figure 5: Three-phase connection with 2 current sensing modules and with low tariff signal circuit for CombiWATT mode, or time schedules. This connection is necessary if the PV-plant output is connected directly to a sealed distribution box, accessible only to the electricity provider. This may be the case for PV-plants made originally only for feed-in tariff, without self-consumption possibility. Current sensing module 1 is connected to the household wiring branch; current sensing module 2 is connected to PV-plant branch. The accuracy of measurement is reduced down to ± 10% in this connection because of the finite impedance of current transformer secondary winding. Caution: Current flow through current sensing modules must always be subtracted in this connection (marked with

arrows on the picture). The same phase sequence must be observed in the regulator and in both current sensing modules!

produced by PV-plant. To make things simple, again only 5 loads are connected, but you may use all 16 outputs. Similarly, you may also connect 3 regulators to 1 current sensing module. In such scenario, each regulator works on one phase and you will get 24 outputs.

Figure 7: Increasing of current measurement range of the device for facilities where main circuit breaker is larger than 3x40A. Transformers 200/5A, or even 400/5A may be used, based on the main circuit breaker value. Secondary coil of current transformers is shorted through the current sensing module (the secondary circuit passes through measuring transformers in the current sensing module). Additional increase of current measurement range may be done if you take the secondary circuit of the current transformer and make several turns through the measuring transformer in the current sensing module (for transformers 200/5A, the best option is to make 4 turns in order to reach optimum transfer ratio 200/20A). For this purpose we recommend using lines, which are not overrated for the nominal secondary current, just to be able to make more turns through the hole of measuring transformer. When connected through external current transformers, the conversion ratio must be set correctly in the control software - see the item Conversion ratio of external CT‘s in the main window of the WATTconfig software.

Figure 8: Connection of an external current transformer (marked as TR, this may be another current sensing module or other compatible current transformer) to measure the current flow through the appliance. The secondary transformer circuit is connected between the Y terminal and any ANDIx input, which must be configured correctly in WATTconfig. In this example, ANDI1 function must be set to power measurement and the Measurement Source option must be set to SSR1. It is also possible to use an external impulse output meter and connect this output to the ANDI input, which must then be set to the S0 pulse counter function.

Figure 9: Connection of external meter with S0 impulse output. The meter can measure, for example, the energy produced from the PV plant. The S0 output of the meter is connected between the GND terminal and the ANDIx input, which must be further configured correctly in WATTconfig. In this example, the ANDI1 input must be set to the S0 pulse counter function, and the Measurement Source option must be set to one of the Lx items if the meter measures the PV power produced.

Figure 10: Connection of supported types of temperature sensors to the regulator. The DS18x20 digital sensors are connected three-wire to the GND, DQ and +5V terminals, analog sensors are connected two-wire between the GND terminals and the corresponding ANDIx input, which must be correctly configured in WATTconfig. In this example, ANDI3 must be set to NTC and ANDI4 to PT1000.

Figure 11: Example for 0-10V signal output from the regulator. The corresponding SSR outputs must be set to the PWM function, and the desired PWM modulation frequency must be set. The outputs SSR 4 to 6 generate the desired signal directly (but the signal may have a significant output ripple at slow PWM modulation), SSR outputs 1 to 3 generate only PWM, so you must use external PWM/0-10V converter to get the desired signal.

Figure 12: Connection of positive SSR anodes (typically A1 +) to an external DC source + 12V when the internal power supply of the controller is heavily loaded. SSR control circuit can be normally powered by + 12V or + 5V terminals. We recommend the + 12V (must be used if the control voltage >5V is required). However, using the two built-in relays, the voltage at the + 12V terminal can drop to + 8V and will not fully drive the SSR 4 to SSR 6 outputs in the PWM / 0-10V function, and some of the built-in relays does not need to be switched on. In this case, connect all SSRs to an external power source as shown in the figure. Firmware since version 1.5 already checks the voltage drop at + 12V terminal and also enables software optimization of the built-in relay consumption.

The controller may be connected only to 230VAC, 50 Hz public electric grids. Regulator must be protected with a circuit breaker - recommended rating is B6A - and connected loads must also be

adequately protected! Installation may only be done when the facility’s main circuit breaker is

turned off!

Upon completion of the installation process make sure to check thoroughly the connection of the regulator and the current sensing module. Also check connection of all pluggable terminal blocks, where NO power grid voltage or voltage outside of tolerances specified in the chapter Technical specifications may be connected! NO other than resistive (heating) loads may be connected to power SSRs! Regular relays CANNOT be connected to SSR outputs! It is prohibited to connect loads with higher than the maximum allowed nominal power! If you fail to observe these rules it is almost guaranteed that you will damage the regulator and lose your warranty!

For the correct operation of the controller, it is absolutely necessary to ensure proper phasing of the measured currents with the internal voltage detector. This can be done by selecting the appropriate phase in the Input Settings tab. It is strongly recommended to connect the controller so that the phase conductor fed to terminal L1 corresponds to the phase conductor wired through the measuring transformer corresponding to the IL1 input, which will allow the measurement to match the default settings of the controller (and therefore the same as required for older models). The IL2 and IL3 current inputs can be connected arbitrarily, the respective phases for these inputs must be set up correctly in the WATTconfig control software.

We strongly advise you to protect your loads connected to the power SSRs with fuses suitable for protection of semiconductors, rather than regular circuit breakers. Please note that SSRs damaged by overcurrent or short-circuit most likely cannot be claimed under warranty. Make sure that solid state relays are correctly connected, as required by their user manual.

No electronic devices (various measuring and protective elements, such as sub-meters and residual current circuit breakers) may be installed between the SSRs and the appliance, since they may be damaged by impulse power! Always install these devices on the line between the fuse and the solid-state relay where constant power is available.

If your facility is located in an area with higher risk of overvoltage spikes due to atmospheric discharge (lightning), we strongly recommend fitting a suitable overvoltage/lightning protection between the distribution box with the main energy meter and the current sensing module!

If any sensors are connected to the ANDI multi-purpose inputs, it is imperative to properly configure their function, otherwise these and/or even the ILx inputs may not work properly!

The current sensing module supplied with the WATTrouter Mx controller is fully compatible with the current sensing module supplied with older types of WATTrouter CWx, WATTrouter CWx SSR, WATTrouter ECO, WATTrouter M and vice versa. The current sensing module installed with these controllers can be used with the WATTrouter Mx controller (and vice versa). However,

please note: The terminal marked GND for these older measuring modules must be connected to the Y terminal of the Mx controller, not to the GND terminal!

If the regulator is constantly connected to PC via USB interface (mostly if long cable is used), we strongly recommend using an USB isolator!

Note: It is allowed to connect only pure resistive loads to power SSRs. These loads cannot be fitted with own electronic control system nor with built-in motors (e.g. fans - see the note below). These loads may only have regular mechanically controlled thermostats and indication LEDs or neon lamps. Almost any regularly produced boilers, immersion heaters, infra radiators, heating floor pads, motor-free dryers (infra dryer), oil heaters, cartridge heaters in a solar tanks, etc. may be used.

Note: Each SSR output is capable of providing power to heating loads with built-in fan for longer time (such as hair dryer, heat radiator). These loads are fitted with a built-in thermal protection, which, if synchronous SSR control mode is used for that load, will disconnect the load for low power of SSR output (in this scenario, the built-in fan’s power is not sufficient to cool down the heating element of the load). Therefore, consider fitting these loads to SSR outputs carefully.

Note: Heating loads connected via residual-current circuit breaker may be connected to SSR outputs.

Note: Heating loads with nominal power up to 2 kW may be connected to relay outputs directly, without using

external contactor.

Carefully examine connection of the controller and then turn off all circuit breakers and deactivate fuse switches for connected loads. Then turn on the main circuit breaker and the regulator circuit breaker (L1 power supply). The LED PWR lights up (power on indication). If the light is off, or if it does not shine permanently, or if the LED ERR starts to flash (error status), proceed according to instructions specified in the Troubleshooting chapter. In default status no output is active and therefore, no load will be turned on.

Now the controller is fitted and ready for configuration.

IN SER TIN G T HE SC-GATEWAY MODUL E

The SC-Gateway module is an optional accessory that provides wireless communication with wireless endpoints. Insert the module to sockets in the regulator according to the images below. Before insertion you must lift the regulator cover with a small screwdriver or similar tool.

Make sure the regulator is turned off before inserting the module!

Keep the proper orientation of the module. Reverse orientation can damage the module! Insert the module gently, without unusual force!

Figure 13: Insert the module to sockets on regulator mainboard, use vertical movement as the arrow indicates.

DEVIC E CONFIGURATION

You will need notebook or regular PC (placed closely enough to the regulator) with USB interface (hereinafter referred to as a computer only). The controller is configured using the WATTconfig Mx control software. The

installation package for this software is available on manufacturer’s web pages. Before installing the

WATTconfig Mx control software you need to install the driver for USB interface.

In order to connect to the USB interface, it is necessary - due to safety reasons - to turn off the entire distribution box before manipulation.

Tip: After you configure Ethernet network connection you may perform all settings including firmware update over the Ethernet interface. You do not need to use the USB interface at all, provided that the parameters of the connected LAN are the same as the default controller parameters (see below), and if there is no conflict between IP addresses or conflict between physical MAC addresses.

Tip: The controller can be monitored and configured via the RS485 interface using the WATTconfig Mx software. An appropriate USB/RS485 converter is required to connect to this interface using a PC. The RS485 interface is reserved for various other protocols (such as MODBUS RTU) which might be implemented in future.

If you cannot continue with the settings (due to any reasons), proceed according to instructions specified in the Troubleshooting chapter.

1. Turn on the PC.

2. Run WATTconfig_Mx_Setup.exe which you may download from manufacturer’s web pages.

3. Follow the on-screen instructions.

SE TTI NG UP MAI N F UNC T ION

1. Click on START button in your PC and run the WATTconfig Mx control software. The system will display

the main software window.

2. Make sure that the controller is turned on and connected to your computer. Make sure that USB

interface driver is correctly installed.

3. Select USB interface connection mode (field next to the "Connect" button).

4. Select correct port for connection. This can be done in the dropdown menu Port in USB/COM driver

configuration window, which will show up by clicking on button Configure connection.

Note: Unlike WATTrouter CWx or WATTrouter M devices the WATTrouter Mx uses a serial port connection

(COMx). This port is always virtual port because the controller is connected via USB. Once more ports are displayed, it is necessary to check in Windows device manager, which port is assigned to USB Serial Port.

5. Click the "Connect" button. The controller should be now connected and the connection indicator (a

stripe) should be displayed in green. If it is not, and the system displays an error message, wait until the USB driver is ready for use in your PC, or inspect the settings in the USB driver configuration window. You may display the window by pressing the Configure button.

6. After establishing successful communication, you should be able to see the current measured values

(power outputs on individual phases, etc.). No outputs should be active ("unused" priority). Also no time schedules should be used.

7. Now you can configure measuring inputs. This can be done on the "Input settings" tab. First, you set

the phase sequence and then the direction of current flows through the current sensing module.

a. Setting up phase sequence: Turn off the PV-plant and turn on a resistive load on each phase

which will be involved in the measuring process. The system will display measured active power on each individual phase. For now, you may ignore the signs of the measured power values. Now, in the Phase field select corresponding phase, based on the actual status recognized by the controller, and press Write button. The configuration will be saved in the controller. If the output values measured on individual phases differ too much from the reality, change the phase for given input and again press the Write button. Repeat these steps for all 3 inputs IL1, IL2 and IL3 until all measured powers are displayed correctly.

b. Setting up the direction of current flows through the current sensing module: As specified in

the previous steps, leave loads on measured phases switched on. When the PV-plant is turned off, all measured power output values must be smaller than 0 or equal to 0. If any of the measured power outputs is positive it means that the phase wire is passing through the current sensing module in a reverse direction. Use the Current orientation field for the relevant phase, select the reversed option and press the Write button. The configuration will be saved in the controller. Now, all measured power outputs must be <= 0. Turn the PV-plant on and turn off all loads. Now, measured outputs must be positive (>=0). If they are not, or if the measured values do not correspond with nominal power ratings of the connected loads, or if they do not correspond with the power output of the PV-plant, you have either still connected another loads (which you don‘t know about, such as various loads in stand-by mode, etc.), or the phase sequence in voltage or in current inputs does not match, or you may

WATTrouter Mx - user manual How to fit and setup the device

Page 24 from 82

have a defect in household wiring. In any case, make sure to inspect the entire electric wiring.

c. You can verify the correctness of measurement input configuration by using the chart "Input

checking oscilloscope". This chart shows measured current waveforms in selected phase,

values are given in units of the built-in A/D-converter (digits), these are not normalized to amps due to performance. This feature should only aid the fitter when configuring the measuring inputs. Always verify with a resistive (heat) load only, so that the phase shift

between voltage and current is zero (󰇛󰇜 )! Moreover, in order to verify the measuring inputs the amplitude of current half-wave should always be greater than 1000 digits (to be sure about the correctness of the settings).

Note: During normal operation there may be shown even "exotic" waveforms. Be sure this is the real current flowing through the phase wire, a superposition of currents flowing through the connected appliances which are not always sinusoidal or their power factor varies from one.

Figure15: Input is fitted correctly - sine wave of the current flowing through a resistive (heat) load is in phase with the voltage. WATTconfig shows negative values on selected phase (consumption). Left image appears when there is normal (default) current flow direction, right image appears for opposite direction. Note: The PV-inverter throughput appears exactly as the opposite, because the current is anti-phased with the voltage. If the inverter performs power factor compensation you can observe corresponding phase shifts.

Figure 16: Input is fitted incorrectly - sine wave of the current flowing through a resistive (heat) load is not in phase with the voltage and either precedes (image left) or lags behind (image right) the voltage by 1/3 of mains half-wave. Measuring inputs are fitted incorrectly and you need to select correct option in the Phase field for respective input.

8. After a successful setup of measuring inputs you may begin to test outputs. This can be done on the

"Output settings" tab. Each connected load must be tested separately. Turn on circuit breaker or activate fuse switch for the first output, and press the TEST button for the corresponding output. The load should switch on. When the load is switched on, the active power drawn by connected load must be detected by the current sensing module on the relevant phase.

WATTrouter Mx - user manual How to fit and setup the device

Page 25 from 82

9. After you have successfully tested all outputs, you may begin to configure the control mode in the

Control settings field. This can be done on the "Other settings" tab. Set this mode either to "sum of all phases" or to "each phase independently", based on the configuration of your 4-quadrant energy meter. If you are not sure how your energy meter is configured, please contact your electricity provider or use the "each phase independently"-mode, which works for any configuration of the energy meter.

In order to use the "each phase independently"-mode, it is necessary to select correct phase for each output, i.e. phase where the corresponding load is really connected. Controller will then try to maintain zero energy flow in each phase ("phase zero"). You may check correct phase assignment again through the TEST button. Within a short time after pressing the button the active power drawn by connected load must be detected by the current sensing module on relevant phase.

As far as your energy meter is configured to evaluate sum of powers in all phases, you may use the mode "sum of all phases". Here the controller will try to maintain virtual zero energy flow. This means that for output switching it takes the sum of measured powers from all 3 phases ("virtual zero"). Here you may try experimenting with both methods, but it is recommended to use "sum of all phases"mode, because it is more effective for the user.

10. After a correct setup of the control mode, you may start to assign priorities and power ratings for

individual outputs. This can be done on the "Output settings" tab. Select priorities of individual loads. The switching process based on priorities may be described as follows:

By default (during night), all loads are turned off. If PV-plant production (available surplus energy) is determined in the morning, the output with the first (highest) priority is switched on. The switching time is different for proportional outputs (their function equals to proportional or PWM) and relay outputs. Proportional outputs are switched on almost immediately (this is the proportional switching), but relay outputs are switched on only if the available surplus energy exceeds the value specified in the Connected power field (there is also a different solution available – see the "Prepend before SSR" function). When the load is switched on (for proportional output it means the load is switched to the value specified in the Maximum power field), the system waits until the power output of PV-plant increases again (sunrise). If additional available surplus energy is determined when the load with first priority is switched on, then load with second priority is switched on in the same mode. The same applies to all outputs. If the available surplus energy decreases, or if another load in the household is switched on, active outputs are disconnected according to preset priorities but in reverse order (first, the load with the lowest priority gets disconnected).

The value in the "Connected power" field should be equal to the power rating of the connected load. For relay output it must be higher or equal to the power rating of the load, otherwise the controller will not operate correctly, and the load will be repeatedly turned on and off. For proportional output this value only configures the control dynamics, but it should be also equal to the actual power rating of the load.

The fields On-delay time and Off-delay time for relay outputs specify the time delay to switch the relay on or off after a condition has been detected to do so. This feature is necessary for loads which cannot be switched on frequently.

Set outputs according to the connected loads and based on your priorities and then press the Write button. The configuration will be saved in the controller. Now the main function of the controller should be configured.

11. Test the main function of the controller, or possibly, modify priorities for outputs and power settings

of connected loads.

SE TTI NG UP COM BIW ATT MOD E

After you have successfully tested the main function, you may start to configure CombiWATT mode, provided a low tariff signal is connected to the controller (it may be used even if single tariff rate is present – see notes below). This can be done on the "Output settings" tab. CombiWATT mode provides constant daily energy supply to the connected loads. This mode is indispensable if you need to heat up water but also e. g. if you use a swimming pool filtering system during cloudy days or when your PV-plant is temporarily out of order. In CombiWATT mode, energy is taken both from PV-plant and from public grid.

Determine the optimal value of energy in kWh for the connected load (for example for a boiler or immersion heater), which you plan to supply the load with every day. For example, for a boiler it is suitable to determine the value of electric energy based on the average consumption of hot water. Usually, electric energy necessary

to increase the temperature of hot water by 40°C equals to:

3600000

][*][*

][

KTlVc

kWhE





. If you enter it

into the formula you will get:

][*0464.0][ lVkWhE 

. For a 180 liter boiler it will be 8.36 kWh. We

recommend to increase this value by the daily heat loss of the boiler and also to modify (reduce) the value based on the actual average consumption of hot water.

Note: If you are heating water for example, the controller does not "know" how hot the water in the boiler is and therefore, the assumed values of the supplied electric energy may be higher than the actual delivered energy (the boiler thermostat may shut it off at any time). If you want to count only real supplied energy to the boiler then connect additional measurement for it according to Figure 8.

Mark the CombiWATT field for the relevant output (output must be activated, which means that the output must be assigned with the relevant priority), enter the established value of the daily electric energy in kWh and press the Write button. The configuration will be saved in the controller.

The CombiWATT mode is activated only if ALL the following conditions are met:

a. The output is activated (priority has been assigned to the output - that means the output is

not in the "not used" status).

b. PV-plant does not produce electric power (active powers at all measured phases are <= (less

or equal to the) CombiWATT production limit field).

c. During the day, PV-plant did not supply the load with the required amount of energy, that is,

the field "Supplied energy" is lower than the value specified in the "CombiWATT [kWh]" field for the relevant output.

d. Low tariff signal has been detected (the info LED "low tariff" is red). Energy from public grid is

always consumed in CombiWATT only if low tariff is present. See note below to learn how to configure this mode if you don't have double tariff rate.

e. The "Time to activate CombiWATT"-field shows zero.

The CombiWATT mode is deactivated if some of the following conditions will apply:

a. The value in the field "Supplied energy" reached the "CombiWATT [kWh]" value for the

relevant output.

b. PV production has been detected at some of the measured phases (active power at some

measured phase is > (greater than the) CombiWATT production limit field).

c. The low tariff signal is turned off.

Reset of energy counters (that is reset of values in the fields "Supplied energy")

WATTrouter Mx - user manual How to fit and setup the device

Page 27 from 82

a. At sunrise. Counters are reset to zero at sunrise time, which is automatically calculated by the

controller.

b. At fixed time. Counters are reset to zero at a preset time.

More information about counter reset processing is available in the chapter Description of WATTconfig Mx items.

Note: For boilers/immersion heaters or any other hot water tanks the CombiWATT mode "does not care" during what time of the day the water is heated and used. The CombiWATT function only supplies the preset minimum daily power to the boiler and thus making sure that there is enough hot water when the recommended configuration is used. In cases when even under the recommended configuration hot water is not available in required amount, we recommend to gradually increase the daily energy limit ("CombiWATT [kWh]") for example, by 1 kWh, in order to make sure that hot water is available and at the same time that not too much energy is consumed from public grid. This is recommended mostly for households where consumption of hot water is high at the evening. Here it may come to the situation where water is sufficiently heated during the present day by the PV-plant, but the next day the plant is not capable of providing the necessary amount of energy (cloudy weather). The CombiWATT mode may also be aided by enforcing the relevant output with a time schedule. Based on user preferences, time schedules may even completely replace the CombiWATT mode. For more information see chapter Setting up time

schedules.

If you do not have low tariff signal available (either you don't have double tariff rate or the signal cannot be utilized) but you still want to use the CombiWATT mode, connect the GND terminal to the LT terminal. In such scenario, the low tariff signal will be active at all times and the CombiWATT mode will be activated after production of PV-plant comes to an end (after sundown).

SE TTI NG UP TIM E S CHE D ULE S

Up to 4 independent time intervals may be set for each individual output. During these time intervals the relevant output may be forced to be switched on, or the switching process may be prohibited (restricted). The enforcing/restricting process may be further conditioned by the presence of the low tariff signal and / or by the status of daily energy counters for the relevant output (field "Supplied energy") or temperature conditions.

The actual configuration of time schedules is done on the "Time schedules" tab. For more set up information, see the chapter Description of WATTconfig Mx items, Time schedules tab.

AN DI INP UT CON FIG URA TION

The controller has 4 multi-purpose ANDI inputs to connect:

1. WATTrouter-compatible external current transformers (e.g. another current sensing module or other

compatible current measuring transformers). These can measure powers exactly as ILx inputs;

2. External meters with impulse output S0, which meets the parameters specified in the technical

specification and its output signal provides information about the measured electrical energy;

3. Analog temperature sensors of NTC type;

4. Analog temperature sensors type PT1000.

ANDI inputs are not required to be used. They play an auxiliary role and provide additional information to the controller. For more information, see chapter Description of WATTconfig Mx items, Input settings tab.

WIREL ESS CO MUN ICA TIO N SETTINGS

Note: This function is accessible, once SC-Gateway module is inserted.

WATTrouter Mx - user manual How to fit and setup the device

Page 28 from 82

WATTrouter Mx optionally integrates up to 6 wirelessly controlled devices which can be purchased as accessories. Wireless connection solution can be applied in buildings, where installation of wire connections between controller and devices would be too difficult.

Attention: Before ordering of this accessory function, assure that wireless devices will be accessible by the controller. The accessible distance is based on construction of the building and it is possible to extend this range by the repeaters. Further information can be obtained from technical support.

This function requires SC-Gateway module which needs to be inserted into regulator. To install this SC-Gateway module, refer to the SC-Gateway user manual. It is also necessary to buy at least one wireless peripheral

(wireless socket or wireless module to be installed on the DIN rail).

How to activate wireless peripherals:

1. Connect wireless peripheral to electrical network and wait till the device gets registered in wireless

network. SC-Gateway module acts as a coordinator of this wireless network and the controller is being informed once new device is detected. In such case, WATTconfig software will show the Add wireless station window. If this dialog does not appear even after longer period (1 minute or longer), the peripheral is probably out of connection range of regulator – proceed according to chapter Troubleshooting.

2. In window "Add wireless station", set the name tag of the station and choose the table line where the

new peripheral should be registered.

3. Upon closing the Add wireless station dialog (see Fig. "Other Settings" tab) press the Write button. The

configuration will be saved in the controller.

4. On the "Output settings" tab, assign to the logic output WLS the configured wireless peripheral by

using the Station and Device fields. Press the Write button. The configuration will be saved in the

controller.

5. Test with Test button, respective output on the peripheral should respond. If it does not, proceed

according to Chapter Troubleshooting.

6. In case of usage of more wireless peripherals, repeat this procedure from point one for each one. Do

not connect new stations to power line at the same moment, because otherwise the identification of new station will be impossible.

FI NIS HIN G T HE CON FIG U RAT ION

After setting up the controller according to previous chapters the controller is fully configured. You may save the preset configuration by pressing the Save button or you may load it at any time by pressing the Open button. This way you may create several different configurations and monitor them for some time and determine which one provides better utilization of energy self-consumption in your facility or household.

After you have completed the settings using the USB port then in case of manipulating within the distribution box turn off entire distribution box, remove the USB cable and turn on the distribution box again.

Tip: In order to maintain continuous monitoring the controller can be kept connected either via USB or Ethernet. If you want to use permanent USB connection, then it is recommended using a suitable USB isolator or USB connection extender via Ethernet (for example Silex 3000GB). To use permanent Ethernet connection you may connect the network cable directly to your network router or switch.

MEASU RED PARAMETERS AND ST ATU S ES

Measured values:

 Power on ph. Lx - the actual value of the active power measured on the relevant phase wire. Positive

value means production (PV-plant supplies power to the grid); negative value means that power is being drawn from the grid.

 Power sum L1+L2+L3 – sum of active power outputs in all three phases.  Voltage at L1 – voltage on phase L1 which powers up the regulator. This voltage value is used to more

accurately calculate the power output than for the older WATTrouter models where the voltage was not measured and a constant value of 230V was assumed. It is also used for calculating the powers on other phases where a similar voltage value is assumed.

Error and info status (gray in inactive status, red in active status):

 Missing voltage L1 – failure of the synchronization circuit that detects the voltage at L1 terminal. This

is a hardware failure of the regulator and it must be replaced or repaired.

 Wrong voltage value L1 - grid voltage is too low (<200VAC) or high (> 260VAC). Firmware since version

1.5 signals this fault separately from the previous general state "Missing voltage L1". The controller will remain functional in this malfunction state, only indicating the problem. Instead of the measured voltage value, a fixed voltage of 230VAC is assumed (as for previous models CWx, M, ECO). If the voltage at terminal L1 is within the specified limits, it is a circuit failure that measures the voltage, and replacement or repair of the controller is recommended.

 Temperature sensor(s) – somewhere in time schedules temperature conditions are defined according

to a temperature sensor (ANDI or DQ input) but this sensor does not work. Change the time schedule configuration or fix the problem with the sensor.

 DC source overload - Voltage level at terminal + 12V drops below + 9V relative to GND. This

malfunction can occur when the internal DC voltage source is heavily loaded. The firmware since version 1.5 checks this and eventually signals this failure. This malfunction lasts for the duration of the cause and for a further 60s afterwards. Typically, this failure occurs when all 8 internal outputs are used or there is overload on the + 12V or + 5V terminals may (there can be for example a malfunction of some digital sensor if powered from + 5V terminal). Please check that the + 12V or + 5V terminals are not overloaded. When the two internal relays are occupied, connect the control circuits of all used SSRs to an external source (see Figure 12). You can also enable the Optimize internal relay consumption feature (see chapter Other settings tab) which might help to reduce the power consumption of internal relays.

 Low tariff – if the low tariff signal is detected the red light comes on, otherwise it is grayed.  Summer time - informs the user that the summer time mode is active. Summer time starts at 2:00 CET,

on the last Sunday in March and ends at 3:00 CEST, on the last Sunday in October. If the option "Use summer time" is not marked on the "Other settings" tab, the indicator remains inactive.

 CombiWATT is active – informs the user that CombiWATT mode is active. This indicator is active if the

condition necessary to run CombiWATT is valid, if the low tariff is active and if the CombiWATT function has been configured for some output.

 Output test is active – informs the user about a status when some of the outputs have been activated

by the TEST button. Output tests done via LAN interface are protected from unauthorized access or intervention.

Page 31 from 82

 SC-Gateway present – informs the user about the presence of the SC-Gateway module in the

regulator.

Output statuses:

 Load power - the power drawn by the load connected to the relevant output. It is either:

a. Estimated power based on the output settings and may not correspond with the actual

power output of the load, or:

b. Measured power using an external current transformer connected to the corresponding ANDI

input. If the output is switched on by the controller, but the assigned ANDI input does not measure any output (for example, the appliance is disconnected by its internal thermostat), the item flashes.

 Supplied energy - daily energy counters counting power already supplied to the relevant output. It is

either:

a. Estimated energy supplied to the load, which is based on the output settings and may not

correspond with the actual amount of the power supplied to the load, or:

b. Measured energy using an external current transformer connected to the corresponding

ANDI input.

These energy counters inform CombiWATT mode or the corresponding time schedule about the energy already delivered to the load and at the same time, they also inform the user about the amount of delivered energy. Counters are reset to zero based on the configuration of "CombiWATT Energy counter reset"-field in the Other settings tab.

Note: In case ad a) the WATTrouter device does not "know" the status of the load and therefore, counters may also show much higher energy values than those actually delivered to the load (for example, if the boiler is heated up during the day and turned off by the thermostat).

 Status output indicators - inform the user about the reason for switching, or possibly about the reason

for output restriction. There are 4 indicators:

a) Blue - it is displayed only if the output is switched on due to basic control process according

to the available surplus energy from PV-plant. This indicator also signals possible off-delay time for the relay output (after being enforced by time schedule or CombiWATT mode).

b) Violet - it is displayed only if the output is switched on by the CombiWATT mode. c) Green - it is displayed only if switching is enforced by time schedule. d) Red - it is displayed if the output is restricted by time schedule.

ANDI input status:

 Power- displays electric power which is measured either with an:

a. External current transformer when the ANDI function is set to power measurement or with

an:

b. External meter with S0 impulse input when the ANDI function is set to S0 pulse counter. The

value is calculated using the following formula:

kWhp

[s].Impt

3600

= P[kW]

Where:

P – final power (this field)

WATTrouter Mx - user manual How to fit and setup the device

Page 32 from 82

tp – period of impulses

Imp

kWh

– number of impulses per kWh (see FB input settings)

The measurement dynamics depends on the impulse frequency. It may be very small for small measured powers. The maximum measurable period of impulses is set to 15 seconds (at 1000 impulses per kWh it corresponds to an output of 0.24 kW). If the measured power is lower, zero is displayed.

 Energy – displays electric energy counted either with an:

a. External current transformer when the ANDI function is set to power measurement or with

an:

b. External meter with S0 impulse input when the ANDI function is set to S0 pulse counter. The

value is calculated using the following formula:

kWh

Imp

[kWh]E = E[kWh] 

Where:

E – final energy (this field)

Ep – initial energy at the input (see FB input settings)

Imp – number of impulses registered by FB input since the moment the impulses were connected to this FB input. These counter values are not displayed.

Imp

kWh

– number of impulses per kWh (see FB input settings)

Impulses are counted only if the controller is operating. It is only an auxiliary and informative feature of the controller. Counted impulses are saved in the internal EEPROM memory every hour. In case of a short time power supply failure these values should not be very different from the actual reality. More frequent impulse saving is not possible due to technical reasons. If these values do not correspond with the value shown on the display of the connected energy meter, modify the field "Energy offset" to match the value of the energy meter, check the "Reset energy"-field and press the Write button.

 Temperature – displays the temperature measured by the corresponding ANDI input when the ANDI

function is set to NTC or PT1000.

Digital temp. sensors:

 Temperature – displays the temperature measured by the corresponding sensor.

Other statuses:

 Configuration/object name - it is used to set label to the facility or the current configuration. Text may

contain maximum of 16 characters in ASCII encoding.

 Sunrise today – it displays time of sunrise for today. This time is calculated directly in the controller

based on the actual calendar date and the actual geographic location of the facility/building (see "Geographic location" on the "Other settings" tab). The calculated time is converted to the current local time based on configuration of the "Use summer time" and "Time zone" settings. The official sunrise zenith, 90° 50' is used. Sunrise time is used to reset energy counters ("Supplied energy"-fields) in the main window, provided that the applicable mode in the field "CombiWATT – Energy counter reset" is selected.

 Day of week – shows the current day of week, which is obtained from the controller date.

WATTrouter Mx - user manual How to fit and setup the device

Page 33 from 82

 Serial number- displays serial number and it is unique for each regulator.  Firmware version – displays actual regulator firmware version.  Date (regulator) – it indicates the real time running inside the regulator (date part).  Time (regulator) – it indicates the real time running inside the regulator (time part).

Note: Regulator real time is backed up with a built-in lithium battery, so it runs even if the regulator power supply is turned off.

 Date (client) – it displays the real-time running on the PC (date part).  Time (client) – it displays the real-time running on the PC (time part).

IN PUT SE TTI NGS TA B

In this tab you may set measuring inputs, multi-purpose ANDI inputs and configure digital temperature sensors.

Note: The ANDI multi-purpose inputs are an extension of FB input functionality from older WATTrouter models that only worked as S0 pulse counter.

Common settings for Measurement input settings and ANDI input settings:

 Label – used to assign a label for the relevant input. Label may contain a maximum of 16 characters

in ASCII encoding. For ILx inputs it cannot be modified.

 Function – is used to select proper function for the input. For ILx inputs it cannot be modified. The

ANDI inputs may perform following functions:

a. Power measurement – default function. Connect WATTrouter-compatible external current

transformers (e.g. another current sensing module or other compatible current measuring transformers). Do not overload the ANDI inputs with bigger primary currents than 15A (which corresponds to secondary current 15mA);

b. S0 pulse counter – connect impulse output S0 of an external meter, which meets the parameters

specified in the technical specification and its output signal provides information about the measured electrical energy;

c. NTC – connect analog temperature sensors of NTC type; d. PT1000 - connect analog temperature sensors type PT1000.

 Current orientation - it is used to change the sign of measured powers, if the current sensing module is

fitted in reverse position, or in cases for example, when it is desirable to pass the wire through the module in reverse direction.

 Phase - it is used to set the physical phase to given input when its function is set to power

measurement. Assign the phase so that the measured currents are in phase with voltage. Check the assignment using a control oscilloscope and a purely resistive (thermal) load on the given phase.

Note: The Phase parameter replaces the "Phase Order Setting" menu from older WATTrouter models and allows you to set any phasing for all inputs with the power measurement function.

 Ratio for external CTs - set this ratio only if you use additional external current transformers (CTs),

whose secondary coils are shorted with a wire passing through measuring coils of the current sensing module, as specified on figure 7. If you use standard connection for WATTrouter device that is, the facility or household supply wire is passing directly through measuring coils as specified on figure 3, then this ratio should be 1:1 (however, this ratio can also be used to calibrate current measurement

WATTrouter Mx - user manual How to fit and setup the device

Page 34 from 82

even in the case of standard wiring without external measuring transformers). External current transformers can extend the measuring range of the controller up to any value, depending on the conversion rate of the external current transformer.

Example: Let us say you want to use WATTrouter Mx in a facility where the main circuit breaker is rated up to 3x400A. In this case you have to buy external current transformers with ratio 400A:5A. Connect/short-cut their secondary terminals using a wire, and at the same time, pass it through measuring coils of the current sensing module (see Figure 7). Now set the conversion rate to 400:5.

However, in order to use the full range of the built-in A/D converter, it is recommended to make 4 turns around the measuring coils to get optimum conversion rate of 400A:20A. Then, set the conversion rate to 400:20.

Caution: Use only external CTs for large facilities and large PV-plant power outputs. If you are using a high conversion rate of external CTs, you have to take into account that (relatively) small power outputs (in the example describing the optimized conversion rate 400A:20A, the limit represents approximately 100 W per phase) are below the resolution capacity of the measuring inputs and therefore, these power values will not be measured and equal to zero.

ANDI input settings:

 Measurement source – use this to setup the energy measurement source for the ANDI input.

Following options are available:

a. Unknown – input counts e.g. energy flowing to a load or another appliance. b. Prod. L1 – input counts energy measured on L1, value will be added to daily production stats

on L1.

c. Prod. L2 – input counts energy measured on L2, value will be added to daily production stats

on L2.

d. Prod. L3 – input counts energy measured on L3, value will be added to daily production stats

on L3.

e. Prod. L1+L2 – input counts energy measured on L1+L2, value will be equally divided to daily

production stats on L1 and L2.

f. Prod. L2+L3 – input counts energy measured on L2+L3, value will be equally divided to daily

production stats on L2 and L3.

g. Prod. L1+L3 – input counts energy measured on L1+L3, value will be equally divided to daily

production stats on L1 and L3.

h. Prod. L1+L2+L3 – input counts energy measured on all phases , value will be equally divided

to daily production stats on L1, L2 and L3 (i.e. counted value will be divided by 3).

i. SSR1 to Relay1 – input measures the power of the appliance connected to respective output. j. WLS1 to WLS6 – input measures the power of the appliance connected to respective wireless

station. The option is displayed only if the SC-Gateway module is inserted into the regulator. The measuring element (external current transformer or external impulse output meter) must be physically connected to the ANDI input and therefore this measurement cannot be easily done wirelessly.

Note: If you measure PV production on several phases with an external three-phase electricity meter, whose S0 output is connected to one ANDI input, and the inverter does not always distribute the production evenly to all phases, you must neglect the differences. If you want to be precise, you have to use 3 ANDI inputs and 3

WATTrouter Mx - user manual How to fit and setup the device

Page 35 from 82

external single-phase meters, or 3 external current transformers. Another current sensing module can also be used to measure the PV production itself in this case.

 Energy offset - this field can be used to set initial values of measured energies. If the values of

measured energies do not match the display on the connected energy meter (for example), put the value of the energy shown on the display into this column and reset impulse counters to zero by marking the option "Reset energy".

 Reset energy - used to reset energy counters to zero.  Number of impulses per one kWh – this column is used to set the number of impulses per one kWh,

when the ANDI input function is set to S0 pulse counter. Set the value according to the label or manual of the connected energy meter, inverter or according to another compatible measuring instrument. It is recommended to use highest possible amount of impulses per kWh to get better resolution for the power fields in the “ANDI input status” group.

Input checking oscilloscope:

This graph is primarily used to check the correctness of ILx metering inputs settings and/or ANDI inputs settings when their function is set to power measurement. However, it can also be used to check ANDI input configuration for other selected functions. From the drop-down menu, select the input you want to check and follow the chart.

The oscilloscope will always display the events at the analog inputs of the WATTrouter microprocessor, which will vary according to the assigned input function:

a. Power measurement - one whole period of measured current is displayed, the value for zero

measured power should be around 2000 digits. For more information about this view, see chapter Setting up main function.

b. S0 pulse counter - logic 1 (about 4000 digits) will be displayed for pulse delay or logic 0 (about 10

digits) for the active pulse from the meter.

c. NTC, PT1000 - the analog value measured by the sensor or amplified by the built-in programmable

amplifier is displayed, which is further processed by the microprocessor for the temperature readout.

In case of connection of external current transformers, S0 pulse outputs or temperature sensors to the ANDI multipurpose inputs, it is imperative to correctly configure their function or otherwise even the ILx inputs may not work properly! You will see this as wrong diagram in the input checking oscilloscope.

Digital temperature sensors:

 Sensor type – select the type of connected digital sensors. All sensors must be of the same type.  Search for digital temperature sensors - starts searching for digital sensors connected to the DQ bus. If

all connected sensors do not appear after performing this function, make sure that the data bus connection is correctly wired and that the shielding is also connected and working. Frequent errors in communicating with sensors occur especially at longer distances and incorrect shielding. The feature is password protected against unauthorized access.

 Labels – used to assign a label for the relevant input. Label may contain a maximum of 16 characters

in ASCII encoding.

OUTPUT SETTING S T AB

On this tab you may set basic parameters for outputs and setup the CombiWATT mode for outputs.

WATTrouter Mx - user manual How to fit and setup the device

Page 36 from 82

 Station – specifies the wireless station – terminal device. Available only for WLS outputs that can be

activated after inserting the SC-Gateway to the regulator

 Device index – specifies the output on the wireless station - terminal device. Available only for WLS

outputs that can be activated after inserting the SC-Gateway to the regulator.

 Function - used to set the functionality of the corresponding output:

a. Relay- the output will operate in On/Off mode (as a relay). b. Proportional - (only for SSR outputs or supported WLS outputs) the output will operate in

proportional regulation mode, by modulating connected load's power according to the available surplus energy.

This mode is only for controlling the output of resistive (thermal) appliances and requires the connection of external power semiconductor relays (SSRs)! This mode can further increase the

flicker (fast changes in mains voltage or fast flashing of light bulbs and fluorescent lamps). Before connecting the appliance to this mode, read the flicker recommendations in the Frequently Asked Questions section of the manufacturer's website.

c. PWM – (only for SSR outputs or supported WLS outputs) the output will operate in proportional

regulation mode, by modulating connected load's power according to the available surplus energy, but the output signal will be PWM, see technical specification for PWM parameters.

Caution: The purpose of this mode is only to control the instantaneous power of external devices which allow this and have corresponding input (such as some battery chargers and heating pumps). This mode cannot be used if external solid state relays (SSRs) are connected to the SSR outputs!

 Label – used to assign a label for the relevant output. Label may contain a maximum of 16 characters

in ASCII encoding.

 Priority – it is used to set priority for the relevant output. First priority is the highest; the eighth

priority is the lowest (in case of SC-Gateway presence it is possible to configure up to 14 priorities). "Not used" means that the output is not activated. Output with higher priority will switch on "sooner" and will switch off "later" (see the chapter Setting up main function). If you are using the "Sum of all phases" control mode, you cannot select the same priority for two or more outputs (except for the "not used" status). In the "Each phase independently" control mode this settings must be applied to each phase. From the first (the highest) priority all the way down to the lowest priority. No gaps are allowed in the priority settings, that is, you cannot set only the 1st priority and the 3rd priority, without setting the 2nd priority as well. WATTconfig inspects priority and phase settings before writing them into the controller.

 Phase – if using the "Each phase independently" control mode you have to set the phase wire for each

output where the relevant load is connected to. The setting must correspond with the reality. Use the TEST button to verify that.

Note: The output phases may not correspond to the physical phase settings for the ILx inputs or ANDI inputs. The reason is that for the inputs physical phase is assigned according to the actual connection of the measuring module and for the outputs logical phase in relation to the inputs ILx.

 3f mode – if using the "Each phase independently" control mode you can set special method of surplus

energy calculation to switch on or off this output. These special methods can be used only for symmetrical three-phase loads (such as 3-phase heating elements, 3-phase heat pumps and others), which have to be connected on 3-phase line. Connect those loads only via external 3-phase contactor

WATTrouter Mx - user manual How to fit and setup the device

Page 37 from 82

or 3-phase power SSR or, if you have 3-phase inverter heat pump, use corresponding control module which can directly control the power of this heat pump.

Put one third of nominal input power of the load to the Connected Power field and set phase and priority according to your preferences (the Phase field only serves here as reference parameter to include this output into correct priority chain). Following special methods of energy surplus calculation are available:

a. Min (L1, L2, L3) – output will be switched on behalf on a minimum surplus energy from all 3

phases

b. Prům (L1, L2, L3) – output will be switched on behalf on average surplus energy from all 3

phases

c. Max (L1, L2, L3 – output will be switched on behalf on a maximum surplus energy from all 3

phases

Within the assignment of one phase there can be combined single-phase and three-phase loads at different outputs. Use this function with extreme caution and only if it is not actually possible to split given three-phase load to 3 single-phase loads (e.g. as the mentioned 3-phase heating element).

 Connected power - it specifies the active power rating of connected load. If power rating is specified in

VA and the power factor cos (Φ) is specified, you may determine the active power rating using

).S[VA].cos( = P[W] 

formula. The connected power value should be equal to the power rating

of connected load for proportional or PWM function, and must be higher or equal for relay function.

 Maximum power – this value applies only for proportional outputs. It determines the maximum

allowed power applicable for the connected load. In many cases this value is equal to the connected power value, but for example, due to limited SSR cooling possibility or due to saving the surplus energy for additional outputs, you may decrease this value. The value in the "Load power"-field may be slightly lower than the selected maximum power value, even if the output is fully excited and maximum power is reached (if this power is assumed and not measured by an ANDI input). The reason is that outputs with proportional function do not switch on fully proportionally but only "quasiproportionally", which means, only in certain switching levels.

Always keep the value equal to the Connected power value in cases where the output is set to the proportional function, causing an increased flicker (fast changes in mains voltage or rapid flashing of light bulbs and fluorescent lamps). The output will always be permanently switched on when fully excited. See the flicker recommendation in the Frequently Asked Questions section of the manufacturer's website.

 Prepend before SSR – allows prepending the relay output before specified number of proportional

outputs. Fill in 1 if you want a relay with lower priority to switch on when load power on nearest higher priority proportional output reaches the relay's Connected power value. Fill in 2 if you want this relay to be switched on when sum of load powers on nearest 2 higher priority proportional outputs reaches the relay's Connected power value. The function works similar for higher values. This function will violate the preset order of priorities. However, it allows using almost all available surplus energy even if heating elements are connected to relay outputs. For example, if you are using a three-phase heating element.

Example 1: heating element 3x2 kW connected and configured in the following way:

- 1st heating coil connected to SSR No. 1, 1st priority, connected power 2 kW, maximum power 2 kW

- 2nd heating coil connected to relay No. 1, 2nd priority, connected power 2 kW, prepend value = 1

WATTrouter Mx - user manual How to fit and setup the device

Page 38 from 82

- 3rd heating coil connected to relay No. 2, 3rd priority, connected power 2 kW, prepend value = 1

If the SSR No. 1 is fully switched and consumes 2 kW of surplus energy and the amount of surplus energy further increases, then the relay No. 1 will switch on and SSR No. 1 will automatically reduce its power. If the surplus energy increases by additional 2 kW so that the SSR No. 1 is fully switched again, then the relay No. 2 will be switched and SSR No. 1 will again automatically reduce the power output. If the power output continues increasing, additional outputs with lower priorities will be connected. Similarly, outputs will disconnect when the PV-plant power generation will decrease.

Note: To make sure that the function works correctly, all 3 heating coils must be active (heated) at the same time or inactive (disconnected by the thermostat). The algorithm will not work correctly if heating coil No. 1 is disconnected by the thermostat and the other two heating coils will continue producing heat. In this scenario, the relay will be continuously connected and disconnected because the controller is trying to keep "virtual zero" or "phase zero", depending on control mode, and is not able to determine from phase wire measurements that heating coil No. 1 is disconnected. However, if we arrange that the real output power of the 1st heating coil connected to SSR No. 1 will be measured with some ANDI input, then the function will work properly even if the heating coils have independent thermostats.

Note: In order to ensure correct function of the algorithm it is necessary that the SSR output - to which the heating coil No. 1 is connected, is assigned with the higher priority than the relay No.1 with the 2nd heating coil. If the coil No. 1 connected to a SSR output has lower power rating than the other two remaining heating coils, then the relays will connect only after the overall power (power drawn by the first coil + surplus energy) exceeds the value of "Connected power" field set for relay No. 1. In this case, the part of surplus energy will be still delivered to public grid as in the case of the default function of WATTrouter controller, without prepend mode.

Example 2: A boiler and 2 other heating elements:

- the boiler connected to SSR No. 1, 1st priority, connected power 2 kW, maximum power 2 kW,

- 1st heating coil connected to SSR No. 2, 2nd priority, connected power 2 kW, maximum power 2 kW,

- 2nd heating coil connected to relay No. 1, 3rd priority, connected power 2 kW,

a) Prepend value set to 0: In this case the 2nd coil will never be prepended and after 4kW

surplus is reached and consumed by boiler and 1st coil the controller will wait until the available surplus is 6kW. Then it connects 2nd coil. In the meantime surplus flows to public grid.

b) Prepend value set to 1: In order to prioritize the 2nd coil, we will take into account only the

load power of the 1st coil, which means that the boiler will always have first priority. So after PV-surplus reaches 4 kW the 2nd coil will be connected (prepended) before the 1st coil.

c) Prepend value set to 2 and higher: In order to prioritize the 2nd coil, we will take into

account the sum of load powers of the boiler and 1st coil. So after surplus reaches 2 kW the 2nd coil will be connected (prepended) before boiler and 1st coil.

Note: The Prepend function does not affect relay output priorities. For example, if the relay 2 is set to the nearest lower priority than the relay 1 but has a higher Prepend value than the relay 1, the relay 2 will not be prepended before the relay 1. Therefore, in this case, higher Prepend value for relay 2 than for relay 1 is not meaningful, so don’t set it.

 Minimum power – for proportional outputs when PWM function is used this value gives the minimum

power for the connected load. The output will not be activated unless available surplus energy exceeds this threshold. Nonzero value can be useful e.g. for proportional control of inverter air

conditioner or heating pump. These devices usually don’t run with less than 1/3 of nominal power. For

WATTrouter Mx - user manual How to fit and setup the device

Page 39 from 82

more information about controlling air conditioners or heating pumps proportionally see manufacturer’s web site.

 PWM-I – for SSR outputs when PWM function is used then this value is equal to the I-component value

of the PID-regulator assigned to this output. The value can be selected between 1 and 1000. Select value according to the dynamics of the connected system (battery charger, heating pump etc.). Start with a small value (1 to 10) and gradually increase the value if the system dynamics is slow. For values less than 100 the dynamics is rather slow so that the system allows switching outputs with lower priorities, to cover available surplus energy. If the Minimum power field is nonzero the control will start after 3 minutes. In the meantime minimum power is held – aimed for softstart of air conditioners or heating pumps.

Caution: In case of a too big PWM-I value the system may become unstable and this status may damage the connected device, when there is no built-in protection in the device!

 Delay - for proportional outputs when PWM function is used this value gives the switch off delay for

case air conditioner or heating pump is connected to this output and controlled by PWM mode. If there is not enough surplus energy to run the device anymore the device will continue to run at minimum power for specified amount of time.

 On-delay time – this value applies only for relay outputs. This delay time runs from the moment a

condition has been detected to switch the relay output on. After the time elapses the relay is really switched on. It is recommended to use the default value, or to slightly increase it if the relevant load cannot be switched on frequently. The value may be decreased down to 2s. However, such small delay time may sometimes cause false load switching. Therefore, we recommend decreasing the value only in certain cases and after proper testing. This time delay is not active in CombiWATT mode.

 Switch-off delay - this value applies only for relay outputs. This delay time runs from the moment a

condition has been detected to switch the relay output off. After the time elapses the relay is really switched off. This feature is necessary for loads which cannot be switched on frequently. The value may be reduced down to 2s. This time delay is not active in CombiWATT mode. Here it is assumed that the low tariff activity time is always sufficiently long in case of double tariff rates.

 CombiWATT – activates the CombiWATT mode for the relevant output (output must be activated, i.e.

have assigned a valid priority). Enter the required amount of energy power, which must be supplied to the corresponding load every day.

 Full power – mark this field if you want to switch the proportional output in CombiWATT at full power,

regardless of the Maximum power setting ("Maximum power"-field).In this way you may eliminate the occurrence of disturbing flicker effect (fast changes in mains voltage or rapid flashing of light bulbs and fluorescent lamps) when CombiWATT if active. If you don't check this field the specified maximum power for the load is used in CombiWATT mode.

 Inverted – this checkbox applies only for relay outputs. When checked, the selected output will be

switched on in inactive status and switched off in active status. The output will not be switched on if any defect/failure is detected, or the output was not assigned with any priority, or the output was not assigned with relay function. In these cases, the output inversion condition does not apply. For example, this feature may apply if there is necessary to "unlock" some device according to available surplus energy.

WATTrouter Mx - user manual How to fit and setup the device

Page 40 from 82

This function can be useful when you want to avoid delivering surplus energy to public grid. Here, typically, one relay output is set as inverted and assigned to last priority. And it is used to block the inverter. If there is inconsumable surplus energy (typically in hot summer) this relay output disconnects the inverter for some time (given by Off-Delay time). After this time the inverter starts again. To block the inverter it is recommended to use analog inputs of the inverter (for inverters which support power reduction). In this configuration the inverter will be disconnected from grid on each WATTrouter failure or when WATTrouter itself gets disconnected from grid.

 TEST – it is used to test the relevant output and load. If you press any of the TEST buttons, all other

control functions regarding the outputs are blocked.

TIME SCH EDU LES TA B

On this tab you may set time schedules for individual outputs.

Up to 4 independent time intervals may be set for each individual output. During these time intervals the relevant output may be forced to be switched on, or the switching process may be restricted. Enforcing or restricting may be further conditioned by the presence of the low tariff signal and / or by the status of daily energy counters for the relevant output (fields "Supplied energy"), or with temperature conditions.

You may use time schedules to create more complex configurations for outputs, based on user preferences. You may also use time schedules to add or possibly replace the built-in CombiWATT mode.

Time schedules operate independently of the basic regulation mode. If used inappropriately,

time schedules may worsen the energy efficiency of your facility. Setting up time schedules

depends entirely on your creativity and provides a wide range of different combinations. Only

advanced users should use time schedules and only after they have been thoroughly familiarized

with the applicable functionalities of this device!

Description of a time schedule option:

 Time schedule mode:

a) Not used – time schedule is not active. b) Restricted – the output will be restricted during the interval specified in the "From - To" field. If

the "From" time is larger than the "To" time, the restrictions or limitations are valid from the "From" time to midnight and on the next following day from midnight to the "To" time. Restriction applies to all activities of this output and has the highest priority. During the time interval neither basic regulation - based on the surplus energy - nor the CombiWATT mode will work. Neither any other time schedule set to enforced mode will work. Output restriction does not prevent outputs with lower priorities from working regularly.

c) Enforced - the output will be enforced/switched-on during the time specified in the "From – To"

interval. If the "From" time is larger than the "To" time, the enforcement is valid from the "From" time to midnight and on the next following day from midnight to the "To" time. Enforcement has the second highest priority and it may be disabled only with another time schedule set to the restricted mode at the same time. During the preset time interval the output enforcement deactivates the basic regulation mode based on surplus energy (only if the Power field is set to 100%). However, it does not affect conditions for the activation of CombiWATT mode, which then can run simultaneously with the enforcement mode. Output enforcement does not prevent outputs with lower priorities from working regularly.

 From – time when time schedule begins  To – time when time schedule ends

WATTrouter Mx - user manual How to fit and setup the device

Page 41 from 82

 Power – it can be configured for proportional outputs (if the function is proportional or PWM) for the

Enforced mode. This field can be used here to enforce the output power as a percentage of the connected power. Thus, the output can be switched proportionally even when switched by the time schedule. If the power is set lower than 100% then such enforcement does not deactivate the basic mode of regulation according to surplus energy. For example, if the output is enforced to 50%, and the surplus is available for the switching on 75%, the output will be switched to 75% of its nominal power. For the Restricted mode, this value is not used.

Always keep the value equal to 100% in cases where the output is set to the proportional function, causing an increased flicker (fast changes in mains voltage or rapid flashing of light bulbs and fluorescent lamps). The output will always be permanently switched on when fully excited. See the flicker recommendation in the Frequently Asked Questions section of the manufacturer's website.

 M to S – shortcuts for weekdays. The time schedule will be active only on checked days.  LT – If you mark this field, the time schedule additionally requires the existence of the low tariff signal

to become active. This function differs based on the time schedule mode, and it is primarily based on the fact that electric power in low tariff is cheaper than electric power in regular (peak) tariff:

a) Restricted mode – the output is restricted only if low tariff is not active. b) Enforced mode – the output is enforced only if low tariff is active.

 Energy – if you mark this field, the time schedule activity additionally depends on the status of the

daily energy counter of the relevant output (the "Supplied energy" fields). Again the function differs based on the time schedule mode:

a) Restricted mode – the output will be restricted only if the daily energy counter exceeds the value

specified in the Limit field.

b) Enforced mode– the output will be enforced only if the daily energy counter did not yet reach the

value specified in the Limit field.

 Temperature – if you mark this field, the time schedule activity additionally depends on the

temperature measured by the specified sensor. In case ANDI input that is not configured to measure temperature is selected, or the temperature sensor selected is not working, then this temperature condition is not used, and the Temperature sensor(s) fault is emitted. There are 2 kinds of temperature conditions which always have built-in internal hysteresis of 1 °C:

c) Lower than – the output will be enforced / restricted only if the temperature is lower than the

assigned limit.

d) Higher than– the output will be enforced / restricted only if the temperature is higher than the

assigned limit.

Tip: Time schedules may also be set for an output which does not have any assigned priority. These outputs may be used for example, as time switch clock etc. Labels and "Connected power" field may be configured for these outputs using the Output settings tab. "Connected power" field of such output is then used to update the daily energy counter.

Note: The conditions described above combine with logic AND within one time schedule. If you need to create a logic OR combination, you need to add a second time schedule with the same time range and another condition. For example, if the schedule should restrict the output function in case where the energy counter exceeds the 5 kWh limit AND the temperature at the assigned input exceeds 60 °C, just use one time schedule where both conditions are set. If this should limit the output function in case where the energy counter exceeds the 5 kWh limit OR the temperature at the assigned input exceeds 60 ° C, it will be necessary to use 2 time schedules with the same time limits but each set for a different additional condition.

Note: Impact-free transition to the basic regulation mode: If the condition necessary for the enforcement of a relay output no longer exists, a basic 10s delay is set for this output. This delay is used to ensure impact-free

WATTrouter Mx - user manual How to fit and setup the device

Page 42 from 82

transition to the basic regulation mode. Similar method is also used for proportional outputs. User-defined offdelay time is not used here.

For more practical samples demonstrating configuration of time schedules, see the chapter Configuration examples.

OTHER SE TTI NGS TA B

On this tab you may configure general control settings and other advanced device settings.

Control settings:

 Control mode - it is used to set the basic control mode:

a. Each phase independently - the controller will control outputs according to measured active

power on each phase wire separately. In this mode it is necessary to correctly set phases for all active outputs. They must correspond with the phase wire where the corresponding load is connected to.

b. Sum of all phases - the controller will control all outputs according to the sum of measured active

powers from all three phases. In this mode it is not necessary to set phases for individual outputs as this does not matter.

 Power offset – this field specifies the difference between the actual sum of measured powers in 3

phases L1+L2+L3 and the value used for the control purposes. For example, if the actual sum of measured powers L1+L2+L3 equals to +500W and the power offset equals to -100W, the controller will use the value of 400W to determine the conditions for output switching. Above terms apply for the "sum of all phases" control mode. For the "each phase independently" control mode this power offset value applies for each phase independently. The lower (more negative) the power offset is, the more power consumption from grid is avoided in transitional statuses as well as in stable statuses where the proportional outputs switch only small amount of power to the load. Transitional statuses are usually identified by 4-quadrant energy meters as "movement around zero", where production and consumption indicators change irregularly and fast. Negative power offset avoid showing up the consumption indicator, but during normal and stable control statuses some surplus energy flows unused into public grid. If you use standard connection and configuration, then it is not recommended to use positive offset.

 PWM frequency - set the desired frequency for outputs with PWM function. This frequency is always

the same for all outputs (and cannot be set differently by hardware). If the slow rate is set, the analog outputs SSR4 to SSR6 will have a significant output ripple. Therefore, if the SSR1 to SSR3 outputs are to be set at a slow frequency and the SSR4 to SSR6 outputs must have a small ripple, then this ripple must be eliminated by an additional RC filter.

 Voltage calibration - it is used to calibrate the voltage measured at the L1 phase. If the measured

voltage differs from the reality by more than about 3V you can calibrate it by specifying the multiplier and the divider in the same way as for the External MT conversion ratio, see chapter Input settings tab. For example, a 100:99 calibration increases the measured value by about 2 V, whereas a 99:100 calibration will decrease it.

By entering incorrect values, the voltage value may go beyond the specified limits (200V to 260V) and the Missing voltage L1 error is emitted!

WATTrouter Mx - user manual How to fit and setup the device

Page 43 from 82

 Internal DC source - informs about the voltage value of the internal DC source of the controller. This

value is used to check for eventual overloading of the internal power supply, which may lead to the "DC source overload" fault. See chapter Measured parameters and statuses for details.

 Optimize internal relay consumption - this feature tries to optimize the consumption of the built-in

relays to decrease the probability that "DC source overload" fault is raised when the two relays are switched on. The feature is active only when both relays are switched on. For details about this fault state, see chapter Measured parameters and statuses. Before activating this function, it is recommended to reduce the DC source load on the + 12V and + 5V terminals, i.e. connect the control circuit of all used SSRs to an external power supply (see Figure 12) when the two internal relays are active.

Network configuration:

 Controller IP address – IP address saved/stored in the controller. The controller uses this address to

"listen" to all UDP and TCP/IP (HTTP) incoming requests. You must always assign a static address. Dynamic address assignment (DHCP Dynamic Host Configuration Protocol) is not supported.

 Controller mask – a network mask to which the controller is connected.  Default router IP address – default gateway IP address. We recommend using IP address of your

router. Since firmware version 1.5, all requests of the newly implemented DNS protocol are automatically routed to this IP address.

 Controller MAC address – physical (MAC) address of the controller. Change this address only if there is

a conflict between physical addresses in your local network.

 UDP port – port used by the controller to listen to UDP requests.  HTTP port – port used by the controller to listen to HTTP requests.

The network configuration will become effective after you reset the controller (see option "Reset unit on config. write").

Date and time settings:

 Synchronize date and time with the client - check this field if you want to synchronize the controller

date and time with the actual time running in your PC. The date and time will be synchronized when the configuration is subsequently written.

 Synchronize date and time with time server - check this box if you want the controller to synchronize

the date and time once a week with the time server on the Internet. In order for synchronization to work, the controller must be connected to the Internet, a valid time server IP address must be set and the default gateway IP address must also be set correctly. The moment of synchronization is calculated from the serial number of the controller and is different for each controller.

In order for the time server synchronization function to work, the controller must be connected to the Internet, the time server IP address or its domain name must be valid and the default gateway IP address must be set correctly!

 Time server (hostname) - time Server domain name. Here changes were made since firmware version

1.5:

Firmware since version 1.5: The time server name is stored directly in the controller and its IP is obtained automatically using the newly implemented DNS protocol. Then, the IP address of the time

WATTrouter Mx - user manual How to fit and setup the device

Page 44 from 82

server is ignored. The default and recommended name is pool.ntp.org, which is a service that automatically assigns the IP address of a particular time server, based on the load of individual time servers and other criteria. You can use the “Test time server and get it’s IP” button to verify the functionality of the server.

Firmware up to version 1.5: The controller does not save the time server domain name and it only appears in WATTconfig. Find the closest time server from available resources on the Internet, enter its domain name and press the "Test Time Server and Find IP" button.

 Time server address (IPv4) - time server IP address stored in the controller. Here changes were made

since firmware version 1.5:

Firmware since version 1.5: The IP address of the time server does not need to be set and detected, just use a valid time server domain name. However, in case the IP of a time server cannot be found from its name, an attempt will be made to contact the time server specified by this IP. Therefore, it is possible to use this field as a backup solution to the specified domain name.

Firmware up to version 1.5: Set this IP either manually, or enter the time server domain name in the Time server (hostname) box, then press the "Test Time Server and Find IP" button.

 Use summer time - check this field if you want the controller to perform automatic switching between

summer and winter time. Based on EU recommendations only summertime is supported, which starts at 2:00 CET on the last Sunday in March and ends at 3:00 CEST on the last Sunday in October. The summertime information is used to automatically modify the current time as well as the calculated sunrise time.

 Time zone - specify the time zone based on your country. The default value uses Central European

time. This value is only used to modify the calculated sunrise time. Time zones outside of multiples of full hours are not supported.

 Test time server and get its IP - press to test the time server and determine its IP address. The IP

address is written to the controller when the configuration is next written. Since firmware version 1.5 there is no need to use this feature, IP is detected primarily from the specified domain name.

 Synchronize time now! - press this button to instantly synchronize the time in the controller (without

requiring configuration writing). If the Synchronize date and time with the client check box is checked, the time is set equal to PC time, otherwise the time server synchronization is performed (if properly configured, otherwise nothing will be done).

CombiWATT settings:

 CombiWATT delay time – specifies the time delay from the moment where PV-plant production is not

detected anymore (after sunset) until CombiWATT can become active. It is recommended to increase the setting if you are frequently using electrical loads (other loads than those connected to the controller), which consume entire surplus energy of the PV-plant for long time. In this case, the controller cannot recognize that PV-plant production is not yet over.

 Time to activate CombiWATT – it displays the remaining time before activation of the CombiWATT

mode. The value is equal to the "CombiWATT delay time" parameter, provided that some surplus energy is still detected. If the value equals to zero and low tariff signal is detected at the same time, the system activates the CombiWATT mode for corresponding outputs.

 CombiWATT production limit – small amount of active production or surplus energy (single units or

tens of Watts) may be detected for facilities with significant capacity loads (blocking capacitors, UPS stations, large number of switching sources, etc.), even though the inverter does not work. The cause

WATTrouter Mx - user manual How to fit and setup the device

Page 45 from 82

may be even the inverter itself. In this case, the controller displays small amounts of positive active power in either phase wire. Reason for this is significant reactive power, which is drawn by those devices and measured by WATTrouter near the "recognition line" between production and consumption. Also watt meters produced by different manufacturers behave in similar way. This item partially tries to resolve this issue by setting additional offset valid for each phase wire.

For example, if the production limit equals to 0.05 kW, CombiWATT mode will already be initiated (provided that also other requirements for the initiation of this mode are met), even if the surplus falls below 0.05 kilowatt in each phase.

 CombiWATT – Energy counter reset – this field is used to reset energy counters, i.e. the "Supplied

energy" fields in the main window. You have two options:

a) At sunrise: counters are reset if the time equals the sunrise time valid for this day. b) At fixed time: counters are reset if the time is the same as the time set in the field called "Fixed

time for energy reset".

 Fixed time of energy reset – it specifies a fixed time for energy counter reset mode according to fixed

time (the previous paragraph, mode b).

Geographic location:

 Latitude - enter the latitude (in degrees) here. The value is used to calculate the sunrise time and

therefore, values specified in degrees are precise enough.

 Longitude - enter the longitude (in degrees) here. The value is used to calculate the sunrise time and

therefore, values specified in degrees are precise enough.

Tip: By changing the longitude you may modify the sunrise time in order to reset energy counters according to your preferences, for example, based on how large area is covered by shadow, etc. If you are not sure, do not modify these values. The default geographic location is set to Central Europe (CZ).

Other settings:

 Language - select the language which you want the WATTconfig software to use after restart. The

Custom item may be used for any other, still not supported language. If you want to use this option, you have to manually translate strings in the custom.xml file into the language you want to use.

 Reset unit on config. write - check this field if you want to restart the controller after each

configuration was written. Controller reset is necessary to change the network settings and also to delete daily energy counters, etc.

 Default tab - Set the tab you wish to appear when you launch the WATTconfig program or web

interface. For WATTconfig software this setting is stored on PC hard drive, the same settings in the web interface is stored directly in the controller.

Authorization settings:

 Require better HTTP security – check this to disallow passing plain text username and password in

HTTP/XML requests (see chapter Description of web interface and XML communication). If checked the authorization will be made using a hash (XML node <sig> replaces here the nodes <UN> and <UP>) and username/ password cannot be changed using web interface anymore (nodes <UNn> and <UNp> cannot be used). If you use a superior system to modify the device configuration this option must be left unchecked because you will not be able to generate the hash there.

 New username - write a new username to authorize writing data to the controller via Ethernet

interface.

WATTrouter Mx - user manual How to fit and setup the device

Page 46 from 82

 New password - write a new password to authorize writing data to the controller via Ethernet

interface.

Note: New login data is written to the controller and can only be used after the configuration is written to the controller. WATTconfig will automatically change the previously saved login so you do not have to reenter it later.

Wireless stations table:

Note: This function is only accessible once the SC-Gateway is inserted.

 MAC address - in this field the MAC address of connected wireless device is listed.  Label - in this field, the wireless devices can be labeled. The label is displayed in drop-down box at the

station field of WLS wireless outputs.

 Delete button – removes the station from wireless network, to make this effective press this button

and write the configuration to the controller.

Firmware update:

 Update firmware button - allows you to update firmware of this product. You can find firmware

updates in the Download section at the manufacturer’s website. If there is an update available you

may download it and install it. The progress of the update process is indicated on screen and it takes (based on your connection type and speed) between 20 to 60 seconds. Firmware update via LAN interface is protected from unauthorized access or intervention.

Update of original firmware is completely safe. The system fully and thoroughly inspects the integrity of the update file, as well as the integrity of data after downloading. In case of a power

failure during the update, you may download the firmware again at any time after your power is restored. If possible, download your firmware via USB or ONLY from your local network (should an error occur during the download, the controller remembers the original network setting only for about 2 minutes). Should you experience an unsuccessful firmware update repeatedly, you may file a claim pursuant to valid trade terms and conditions. It is strictly prohibited to modify the downloaded file in any way. If you modify the downloaded file and even if the system inspected the integrity, you may still damage your product and lose your warranty!

Web client feature:

Web client data exchange button – opens a dialog box where XML based data exchange in web client mode can be configured. This feature is available since firmware version 1.5. See chapter Webclient based XML data exchange.

ST ATI STI CS TAB

This tab displays daily, weekly, monthly and annual statistics on production, consumption and surplus (excess) energy. Statistics can be exported to *.csv files if desirable.

Note: The controller stores basic statistics into the internal EEPROM memory and more detailed statistics on the SD card. These more detailed statistics cannot be displayed in WATTconfig or in a web interface, but can be imported from the SD card to a computer as a * .csv file, which can be opened, for example, in MS Excel.

Through current sensing module you can obtain only the consumption and surplus (excess) energy. To display data on production and self-consumption, it is necessary to connect a S0 pulse output to some ANDI input from an external meter, which measures the power of the inverter. Or you can measure this power directly with an external current transformer connected to the ANDI input. Alternatively, connect inverter directly to the ANDI input when the inverter is

WATTrouter Mx - user manual How to fit and setup the device

Page 47 from 82

equipped with a compatible impulse output. It is also necessary to configure the "Measurement source" field on the Input settings tab for this ANDI input, in order to let the controller process the counted value properly.

Values are approximate! The device does not know the exact values from utility/billing meters!

Daily statistics are reset every time just after midnight, i.e. at 0:00 A.M. At the same time, daily values from the just finished day are moved into history. When you change the date in the controller you may cause irreversible deletion of stored history!

Daily statistics:

 Show for day –select the date for which to view daily statistics. You can display them for current date

and last 31 days.

 Phase Lx–displays information about the surplus (excess) energy, normal and low price energy tariff as

well as (optionally) PV-production, when counted with an ANDI input, in the current or selected day.

 Total L1+L2+L3 – displays summary data from all three phases. The calculation of these data depends

on the selected control mode -the "Control mode" field on the Other settings tab:

a. Each phase independently – summary data are simply the sum of the fields from all 3 phases b. Sum of all phases – summary data are updated continuously from immediate results. In this

control mode summary data are not the simple sum of the displayed values in each phase (in one phase the surplus energy may cover consumption in different phase, etc.).

 Daily output status- displays the assumed or really measured amount of energy supplied to each load

in the current or selected day. Since the statistics are reset every time just after midnight, these values will not correspond with the values in the fields "Supplied energy"(reset of those fields is generally done at different time).

 Daily ANDI input status- displays the measured energy at corresponding ANDI input in the current or

selected day. In brackets on the right, the configured measurement source is also displayed. If ANDI input is configured to measure temperature, the item always remains zero. Temperatures are not counted in stats.

 Read from SD card – use this button to read more detailed statistics from the built-in SD card. These

statistics will be saved to a *.csv file which you can load e.g. in MS Excel.

 Erase internal stats – use this button to delete all statistics stored in the built-in EEPROM memory.

Confirmation dialog will be shown first.

 Erase SD card stats – use this button to delete all statistics stored in the built-in SD card. Confirmation

dialog will be shown first.

 Charts – they show a graphical interpretation of the daily statistics on production and consumption.

Charts in each phase indicate the part of corresponding summary data (pie slice or part of the bar). The self-consumption value is calculated from this formula: self-consumption = production – surplus energy. Self-consumption values are not available unless the displayed production value is bigger than measured surplus energy value.

Note: For very small energy values (typically immediately after resetting statistics after midnight) internal rounding to 0.01kWh is significant for displaying the charts .In these cases, pie charts may not be displayed absolutely correctly.

Weekly statistics:

 Chart -shows the5 main summary data (production, surplus energy, self consumption, consumption in

normal and low tariff) in bars for the last 7days.Double click on the bar to view the day in the daily statistics.

Monthly statistics:

 Production chart - displays summary data on production (production +surplus energy) in the last 31

days. Double click on the bar to view the day in the daily statistics.

WATTrouter Mx - user manual How to fit and setup the device

Page 48 from 82

 Consumption Chart - displays summary data on consumption (self-consumption, consumption in

normal and low tariff) in the last 31 days. Double click on the bar to view the day in the daily statistics.

 Export- exports monthly statistics to a *.csv file that can be opened e.g. in MS-Excel.  Import - imports monthly statistics from the *.csv file. The file must contain monthly statistics stored

in WATTconfig Mx, M, or ECO. This feature can transfer statistics from another device. The daily input and output states are not imported. This import only replaces internal statistics and does not affect data stored on the SD card.

Annual (yearly) statistics:

 Production chart – displays summary data on production (production +surplus energy) in the last 12

months.

 Consumption Chart – displays summary data on consumption (self-consumption, consumption in

normal and low tariff) in the last 12 months.

 Export- exports annual statistics to a *.csv file that can be opened e.g. in MS-Excel. Exports data for

last 24 months.

 Import - imports annual statistics from the *.csv file. The file must contain annual statistics stored in

WATTconfig Mx, M, or ECO. This feature can transfer statistics from another device. This import only replaces internal statistics and does not affect data stored on the SD card.

Note: Actual day will take effect in the annual history (current month) after moving into history (after midnight).

All time statistics:

 Counted from date – this is the day where counting all time statistics started from.  Phase Lx–displays information about the surplus (excess) energy, normal and low price energy tariff as

well as (optionally) PV-production, when counted with an ANDI input, in the current or selected day.

 Total L1+L2+L3 – displays summary data from all three phases. The calculation of these data depends

on the selected control mode -the "Control mode" field on the Other settings tab:

c. Each phase independently – summary data are simply the sum of the fields from all 3 phases d. Sum of all phases – summary data are updated continuously from immediate results. In this

control mode summary data are not the simple sum of the displayed values in each phase (in one phase the surplus energy may cover consumption in different phase, etc.).

 Charts – they show a graphical interpretation of the daily statistics on production and consumption.

Note: All time statistics may not agree with the summarized values in annual statistics as this feature was first added in firmware version 1.5. All time statistics are not retrospectively deducted from annual statistics when updating to version 1.5.

LOG TAB

This tab displays error and warning log. For example, the system displays detected communication errors. Since firmware version 1.5, there is also a listing of up to 20 error messages stored in the controller from the latest to the oldest. This error list is stored in the nonvolatile memory (EEPROM) so that it remains saved in the controller in case of a power failure.

 Delete error list - press this button to clear the error list in the controller.  Save error list - press this button to save the error list to a CSV file on your PC hard drive.  Clear log – use this button to clear log contents.  Save log – use this button to save the log as text file on your PC hard drive.

US B/C OM DRIVER CO NFI G URATION WINDOW

In this dialog box you may specify connection parameters for the USB or RS485 interfaces.

Port settings:

 Port – if the driver is properly installed and the controller is connected to the computer, the

appropriate COMx port can be found in the pop-up menu. If multiple or none ports are shown, make sure that the USB serial port or your RS485 converter driver installation in Device Manager is correct. Here, you can also find out which port is used for communication. The communication parameters are fixed: 115200 Bd, 8N1.

Timeouts:

 Default read timeout – maximum time necessary to receive response from the controller. Modify the

value (increase) only if you experience communication problems.

Buttons:

 Default – sets default communication parameters.  OK, Cancel – standard confirmation and cancellation of the dialog box.

LAN/U DP DRIVER CONFIG URATION W INDOW

In this dialog box you may specify Ethernet interface parameters and UDP protocol settings.

UDP protocol settings:

 Select profile - it is used to select connection profile. Connection profiles are used to quickly configure

connection settings. They are useful e. g. for connections from local and public networks where you must switch between two IP addresses. New profile may be created by pressing the "New" button. The new profile stores the current IP address and UDP port settings. Created profiles may be deleted by the Delete button.

 IP address (IPv4) – IP address used to access the controller. You may specify the controller IP address

in your local network, or if you use suitable NAT settings for your router you may also specify the global Internet address of your router. Before you changing the IP address, you have to change the IP address settings directly in the controller - see the "Other settings" tab.

 UDP port – UDP port used to access the controller. The default value is 50000.

Note: If you cannot establish communication via Ethernet, connect via USB and check the current LAN settings in the controller.

Timeouts:

 Default read timeout – maximum time necessary to receive response from the controller. Modify the

value (increase) only if you experience communication problems.

 Communication delay after reset – if you are connected via LAN the "reestablishment" of the

connection after the controller reset may take longer than if you are connected via USB or RS485. Modify the value (increase) only if you experience communication problems after controller reset (typically, after you loaded new firmware to your controller).

In this window, you can set options related to XML data exchange functionality in web client mode. This feature is available since firmware version 1.5. The data has the format described in chapter Data record for web client

WATTrouter Mx - user manual How to fit and setup the device

Page 51 from 82

based XML exchange. In this mode, the controller periodically sends the specified XML data record to the specified server using the HTTP protocol. Data can be processed by any user script on the server. The advantage of this communication is that the controller works as a regular web browser and does not require a fixed IP address (or, at least, often unchanging dynamically allocated IP address) as is in the case of standard access to the controller from outside (the Internet).

Feature configuration:

 Server hostname – enter domain name of the server accepting data.  Script URL – enter script URL on this server.  HTTP port – enter a port where the server listens to these HTTP requests.  Sending period - specify the periodicity of the transmitted data. Can be set from 1 s to 86400 s (1 day).  Successful exchanges – can be used to check the connection and functionality of this feature. This

counter is incremented after each successful data exchange.

CONFI GURATI ON EXAMPL ES

These examples only demonstrate the potential use of the device - in most cases however, settings must be modified. The examples were created in version 1.0 of the software. In newer versions there may be other advanced options to further increase the efficiency of the system.

EXAMPLE NO. 1 – ON E L OAD ONLY

Boiler with nominal power rating of 2 kW, 200l of water, average cold water temperature at the input is 12 °C, hot water target temperature 50 °C, average daily water consumption is 160 l. The daily amount of electric

power necessary to heat up the entire boiler (without taking into account heat losses) is:

kWh

KTlVc

82.8

3600000

38*200*4180

3600000

][*][*







Average daily losses of boilers with these parameters represent approximately 1.5 kWh. If you use 160 l of hot water and you take into account heat losses, the daily supply of electric power is approximately 8.6 kWh.

Boiler is connected to SSR output No. 1, WATTrouter device uses low tariff signal and the boiler operates under CombiWATT mode.

With the ”Each phase separately”-control mode set, in this configuration with one appliance connected to L1 we cannot use surpluses in phases L2 and L3. In the ”Sum of all phases”-control mode, it is irrelevant to which phase wire the boiler is connected and the Phase fields cannot be changed. The ”Sum of all phases”-control

mode is better, but your 4-quadrant meter must allow it.

Page 54 from 82

The time schedule is configured for the boiler between 15:00 and 19:00.It becomes active only if the low tariff is available and, moreover, until the supplied energy to the boiler did not exceed the specified limit. This allows you to heat up water for evening use, provided that during morning and afternoon hours the boiler was not sufficiently heated up by power supplied by the PV-plant. If low tariff is not active from 15:00 to 19:00, the basic control mode according to available surplus energy continues even during this time period.

WATTrouter Mx - user manual How to fit and setup the device

Page 55 from 82

EXAMPLE NO. 2 – 6 LOADS, CONTROL MOD E = SUM OF ALL PHASES

The same boiler as specified in example No. 1, swimming pool filtering pump and 6 kW instantaneous water heating for the swimming pool (pump and three-phase heating element). Recommended peak power output of the PV-plant is more than 8 kWp.

Boiler heating process has 1st priority (SSR1 No. 1).Requirements are the same as in example No. 1.

Filtering pump has 2nd priority (relay No. 1), nominal motor rating 0.3 kW (value in VA is usually not specified here), and it must run exactly for 6 hours per day and the minimum switching time is 5 minutes. The daily amount of required power for this motor is 1.8 kWh. If there is not sufficient amount of sunshine available, the system will switch back to the low tariff. The motor should not be running at night between 23:00 and 5:00 not to disturb people during night (this also depends on the local low tariff time schedule so that the motor can get a chance to run). If the boiler is large enough and does not often turn off by thermostat, we can set the “Prepend before SSR” condition to 1 for the filtering pump to make better use of surpluses.

Heating pump has 3rd priority (relay No. 2), power output 0.16 kW and it must run always if the heating element of the pool heating is on. The typical off delay time for the pump is 1 minute. We only want to turn the swimming pool heating when there is surplus energy available. Make sure swimming pool heating is fitted with a thermal protection!

Heating elements are connected to the remaining outputs with lower priorities (SSR outputs).

We recommend using separate contactors for motors, but due to their low power consumption rate it is not really necessary. WATTrouter device uses low tariff signal and the boiler and swimming pool filtration motors operate under CombiWATT mode.

WATTrouter Mx - user manual How to fit and setup the device

Page 56 from 82

Time schedule for boiler is set the same as in example No. 1.

Two time schedules are assigned for pool filtering pump. The first of them describes restriction of the output during "daytime" between 8:00 and 23:00. This restriction ensures the motor runs approximately 6 hours (1,8kWh / 0,3kW) and therefore, it applies only if the output energy counter (field Supplied energy) exceeds 1.8 kWh. The second time schedule restricts operation of the motor between 23:00 and 5:00 without any special requirements or conditions. The necessary prerequisite for correct application of these two time schedules is correct configuration of daily energy counter reset. As reset mode there must be selected "at sunrise" or "at fixed time". The fixed time for second case should be selected in the morning before 8:00.

EXAMPLE NO. 3 – 7 LOADS, CONTROL MOD E = EA CH PHASE IND EPENDEN TLY

Loads specified in example No. 2 but more complex connection. Control mode is set for each phase independently. In this example, it is necessary to distribute the appliances as uniformly as possible to the individual phases, which is more complex and rarely can be done optimally.

Connect the following to L1 phase:

- boiler has 1st priority (SSR No. 1).Requirements are the same as in example No. 1.

- pool filtering pump has 2nd priority (relay No. 1).Requirements are the same as in example No. 2. Again we can set the “Prepend before SSR” condition to make better use of PV-surpluses.

Connect the following to L2 phase:

- heating pump has 1st priority (relay No. 2).Requirements are the same as in example No. 2.

- 1st heating coil with 2nd priority (SSR No. 2).

Connect the following to L3 phase:

- auxiliary contact with 1st priority (SSR No. 5 operating as a relay), will also turn on the heating pump connected actually to phase L2 (here, a small amount of power may be drawn from the public grid at phase L2, but in order to prevent it we would have to use two circulation pumps).

- 2nd heating coil with 2nd priority (SSR No. 3).

- optionally also the 3rd heating coil in the 3rd priority (SSR No. 4), however, only if the assumed PV-power at this stage is enough and it pays to buy another SSR.

Page 59 from 82

EXAMPLE NO. 4 – 5 LOADS, CONTROL MOD E = EA CH PHASE IND EPENDEN TLY

Boiler and pool filtering system specified in example No. 2 plus 2 resistive electric heaters and a heating pump used to heat the swimming pool. Everything in more complex connection plus control mode set for each phase separately.

Each electric heater draws 2 kW and should be powered only with the PV-surplus energy, independently of the house hold primary heating system. These heaters must be deactivated at summer time - either through built in thermostats, by deactivating fuse switches for respective outputs or by deactivating them in the software.

The heating pump draws power of 1.3 kW and it is powered only with the PV-surplus energy, or manually, independently of the WATTrouter device.

Connect the following to L1 phase:

- boiler has 1st priority (SSR No. 1).Requirements are the same as in example No. 1.

- pool filtering pump has 2nd priority (relay No. 1).Requirements are the same as in example No. 2.

Connect the following to L2 phase:

- 1st electric heater with 1st priority (SSR No. 2).

- heating pump with 2nd priority (relay No. 2).

Connect the following to L3 phase:

- 2nd electric heater with 1st priority (SSR 3).

You may activate the ”Prepend before SSR” function for relay outputs, in order to better use the PV-surplus energy at L2, when the heating pump and electric heater operate at the same time.

ETHERNET NETWORK CON F IGU RAT ION

WATTrouter Mx allows monitoring and configuration via Ethernet socket. In order to establish the communication you must correctly configure network connection.

Always entrust the configuration of the network and Internet access to the controller to a person with the necessary technical skills. Problems associated with network settings, except for demonstrable malfunctions of the regulator network interface, are not included in the manufacturer’s technical support policy and cannot be claimed.

It is recommended to perform regulator network settings via USB interface (when you connect via Ethernet and change network parameters you will probably always loose connection).

In order to successfully set network parameters you must know parameters of your local network. It is necessary to know the following parameters:

 IP address of your router or another access point to your local network (if it is installed),  Free range of IP addresses, which means that you need to know what addresses do not belong to the

range of dynamically assigned addresses, provided that your DHCP server is on and also what addresses are not static addresses of other devices in your local network.

 Local network mask used by all devices connected to your local network.

The controller allows you to set only static IP address. The controller does not support dynamic IP address assignment because most users connect to the controller from Internet through a network router and its NAT port mapper, for which static IP address is required.

LOCAL NE TWO RK CON NEC T ION SETTINGS

Network connection is configured in the "Other settings" tab, group "Network settings".

Network configuration changes will become effective only after you reset the regulator (see option "Reset unit on config. write").

 IP address: enter the IP address where regulator will be accessible. Make sure that the address does

not collide with other devices in your local network. For example, if the IP address of your router is

192.168.2.1, set it to 192.168.2.10, provided that this address is not already used by other device in your local network and also provided that this address does not belong to the range of dynamically assigned DHCP server addresses in your local network (DHCP server is usually active in your router).

 Mask: enter the mask of your local network. In majority of cases the value is 255.255.255.0.  Default gateway: set IP address of network device where the controller will try to send requests

outside of your local network. In majority of cases it is the IP address of your router. In this case the address is 192.168.2.1. If you do not have such device, enter another IP address not used in your local network. In this case, requests directed outside of your local network will not be acknowledged.

 Controller MAC address: enter the physical/MAC address of your controller. Change this value only if

there is another device with the same MAC address in your local network.

Note: WATTrouter Mx devices do not have their own IP address range registered within the IEEE, because network communication is only additional feature and not the main function of the device. If

you change MAC address you must respect specific requirements applicable to these addresses!

 UDP port: enter the value of the UDP port where the regulator will listen to incoming UDP requests

from WATTconfig software. Change this value only if there are several UDP servers in your local network sharing the same UDP port, or if you want to increase protection against unauthorized access

WATTrouter Mx - user manual How to fit and setup the device

Page 62 from 82

to your network. If you change UDP port in the regulator it is also necessary to change the UDP port settings in the LAN/UDP driver configuration dialog.

 HTTP port: enter the HTTP port value where your controller will listen to incoming HTTP requests -

that is requests from web browser. Change this value only if there are several web servers in your local network (which will be accessible from the Internet), or if you want to increase protection against unauthorized access to your network.

SE TTI NG UP INT ERN ET A CCE SS

In order to connect to the Internet we recommend you to have an active global static IP address. If you have only dynamically assigned IP address, you may see its value in your router info page. Dynamic IP address may also be used, but depending on your Internet connection provider, this address may vary more or less frequently. If your controller is not accessible from the Internet, always check the WAN configuration in your router first.

The controller may be accessed from the Internet only through routers or other access points which support the NAT (Native Address Translation) function or other similar function, which is used to translate global IP addresses and ports into local network IP addresses/ports.

The following text describes a sample Internet connection configuration, using a regular broadband router Edimax BR-6204Wg-M. See the below:

 On the NAT Settings tab check the field Enable NAT module function, and press Apply and then

Continue.

 On the Port forwarding tab check Enable Port Forwarding, fill out the NAT table for as seen on the

picture and check Apply and then again Apply, which will save the settings in the router and your router will restart.

NAT configuration is similar for other routers.

If your global address (static or the currently used dynamic address) is 80.200.50.6, then in order to access your regulator from the Internet via HTTP protocol, enter the following address into your web browser (we recommend creating a bookmark in your browser):

http://80.200.50.6/

In order to access your regulator from the Internet via WATTconfig, enter the same IP address into the LAN/UDP driver configuration window, here 80.200.50.6.

If you experience conflict between HTTP ports, provided you have several web servers in your local network which you want to be accessible from the Internet, it is necessary to select different HTTP port in the controller, for example widely used alternate port No. 8080, instead of the standard port No. 80. To access the controller then just enter the following address into your internet browser:

http://80.200.50.6:8080/

DESCR IPTION OF WE B I N TER FAC E AND XML COMMUNIC ATI ON

WATTrouter Mx devices can be monitored and configured using regular Internet browsers. Web interface can be used only if the controller is connected via Ethernet.

Figure18: Device web interface.

Using the web interface you may monitor and configure all controller parameters as if you would do using the WATTconfig software, except for input checking oscilloscope, wireless network settings, time server testing, statistic export/import, firmware upgrade and web client data exchange settings.

Web interface is implemented in your Internet browser by using AJAX/XML technology and therefore, you have to allow JavaScript.

Monitoring the controller activity and configuring it may also be implemented into any superior control system capable to send or parse XML data. However, the implementation requires certain knowledge of HTTP protocols and XML files.

Authorization to write a new configuration was not designed using common HTTP authentication, but instead of it the login data is embedded into each configuration write request. This mechanism simplifies the implementation on the superior control system side where using HTTP authentication could be problematic.

In order to monitor and configure your controller you may use following HTTP/XML requirements. Description of individual XML data are listed as HTML/XML comments directly embedded in the XML data listings:

1. GET /meas.xml

TROUB LESHOO TIN G

The following table shows the most frequent problems and usual solutions:

Problem description

Possible causes

Solution

The regulator has been fitted according to the manual but after you switch on the circuit breaker no LED lights up or flashes.

The circuit breaker is on but the supply voltage is missing.

Check or measure whether there is any voltage between terminals L1 and N.

Regulator failure/defect

Replace the regulator or take it to repair.

The regulator has been fitted according to the manual but after you turn on the circuit breaker the green LED quickly flashes, the regulator does not work and the WATTconfig software shows BOOT firmware version.

The regulator runs in the boot mode without any application firmware

Use the WATTconfig software and load the newest firmware version or load the version you prefer. In this scenario, you have to load the application using USB or RS485 interface, which is not blocked by the regulator access authorization.

The regulator does not communicate with computer

The regulator has no voltage

Check whether green LED PWR is on and the regulator is powered.

Computer is not properly connected with the regulator

Check the USB/network cable connection, try using different network cable, or try the cable with different device (printer for example). If there is problem with network connection you may have a problem with your router or with other network components. Try to restart your device or try to connect the network cable to another port. Your device may also be incorrectly configured - the same applies to local network configuration settings. Should you experience problems contact a computer or network expert. If there is problem with the USB connection then always try the newest USB driver.

Computer cannot detect connected regulator.

Check USB/network cable connection. When USB device is being registered in your PC, the yellow LED COM must flash temporarily. If your network cable is connected correctly, at least one LED on the regulator network connector must be on.

USB interface driver was not correctly installed in your computer

Make sure the USB interface driver is correctly installed and Windows device manager detects it as a USB serial converter.

USB interface driver is not configured properly

Use the USB/COM driver configuration window in WATTconfig and reset all parameters back to default values.

WATTrouter Mx - user manual How to fit and setup the device

Page 73 from 82

LAN/UDP interface driver is not configured properly

Use the LAN/UDP driver configuration window in WATTconfig to check the validity of IP address and UDP port. Connect to the regulator using USB in order to determine the current network configuration stored in the regulator (use the Other settings tab). IP addresses and UDP ports must have the same configuration.

The Log window records communication errors

A very few communication errors is considered a common status and it depends on the actual load put on Microsoft Windows OS, the local network, or on the operating system running in the regulator. However, if there are many errors inspect the functionality of your PC, or it may also be a conflict at the USB interface in your PC, USB driver may be outdated or your Ethernet may be overloaded or malfunctioning. If you are connected to the Internet, large occurrence of communication errors (packet losses) is considered normal status.

Overloaded Ethernet

Your local network or Internet connection is temporarily out of order, overloaded with other transfers, etc. Try to reconnect later or ask a network expert for advice to optimize your connection.

Regulator failure/defect

Replace the regulator or take it to repair.

Measured powers on ILx inputs are not displayed or they are displayed incorrectly

The current sensing module is not connected

Connect the current sensing module according to this manual.

Incorrect phase sequence

Make sure that for all ILx inputs the “Phase”

field is correctly set. Perform the settings according to chapter Setting up main function and check with Input checking oscilloscope.

Incorrect current orientation settings

Make sure that for all ILx inputs the

“Current orientation” field is correctly set.

Perform the settings according to chapter Setting up main function.

The ANDI inputs are configured incorrectly

Wrong configuration of ANDI inputs can cause incorrect measurement of ILx inputs! Disconnect all CTs or sensors from ANDI inputs and check the ILx function. If everything is OK then again connect the sensors to respective ANDI inputs and select their functions exactly according to connected sensors.

Regulator or current

Replace the regulator and/or current

WATTrouter Mx - user manual How to fit and setup the device

Page 74 from 82

sensing module defect

sensing module or take them to repair.

There are suspicious waveforms shown in chart "Current wave oscilloscope"

This is normal

During normal operation there may be shown even "exotic" waveforms. Be sure this is the real current flowing through the phase wire, a superposition of currents flowing through the connected appliances which are not sinusoidal or their power factor varies from one.

Positive measured power value (production) differs too much from the value on the inverter display

There is connected some load, which decreases this value.

No defect

Inverter shows approximate values, or the status is not stable

No defect

Incorrect phase sequence or incorrect current orientation settings

Follow the steps specified in the previous troubleshooting item.

Low tariff signal is missing

Low tariff signal is not connected

Connect the low tariff signal to LT terminal. You must connect the signal through an auxiliary relay as specified in this manual.

Low tariff signal is not active

Wait until the signal is active, or manually test the auxiliary relay by switching it on (some relays offer this option).

Regulator failure/defect

Replace the regulator or take it to repair.

ANDI inputs do not work

Input function set incorrectly

For ANDI inputs it is absolutely necessary to correctly setup input function according to connected input device/sensor.

Measurement with external current transformers does not work

Connect a compatible external current measuring transformer, such as another current sensing module or other WATTrouter compatible CT. Also check the Phase and Current Orientation settings which should follow the same principles as for the ILx inputs.

S0 impulse output from external meter/inverter is connected with reverse polarity

Observe polarity of the device output (energy meter, inverter).

Signal coming from the output is an unsupported impulse signal

Use only device with S0 impulse output whose signal carries information about the measured energy and has a minimum impulse width of 1 ms. Signal parameters are described in chapter Technical specifications.

Connected analog temperature sensor does not work

Connect only compatible sensors according to chapter Technical specifications. Select ANDI input function that corresponds with

WATTrouter Mx - user manual How to fit and setup the device

Page 75 from 82

the sensor type. Measure the sensor resistance and voltage at the ANDI terminal against the GND terminal. For NTC, the resistance must be about 10 kΩ at 25 °C, the voltage approx. 1.67 V. For PT1000, the resistance of approx. 1100 Ω at 25 °C, voltage approx. 0.35 V.

Regulator failure/defect

Replace the regulator or take it to repair.

Digital temperature sensors do not work

Incompatible sensor

Use only compatible sensor with original chip inside (DS18B20 or DS18S20).

Wrong connection

Connect according to the connection information on the sensor. Do not connect sensors where this information is missing. Always connect in 3-wire way (i.e. with power supply)

DQ data bus too long

Shorten the bus, test the sensors one at a time. If they operate individually but all at a time not, the DQ bus capacity is too high. In this case, you can also try adding a 4k7 resistor between the DQ terminal and the +5V terminal.

Sensor bad

The sensor may be damaged, measure the sensor power consumption (from terminal +5V) with a milliammeter, the input current should match the sensor specification, i.e. max. 2mA. A faulty sensor sometimes has an increased power consumption and is warming up (this is not a rule). If there are more sensors on the sensor bus, try one at a time and identify the faulty sensor.

DQ input failure

This is not probable but possible, especially if the sensors work on a different device. Replace the regulator or take it to repair.

The TEST button cannot be used to switch on some of the connected loads

The relevant load is not connected or it is connected incorrectly

Check the connection of the relevant load and switch on the corresponding circuit breaker or fuse switch.

The load is connected correctly but cannot be switched on

Check whether the load is fitted for example with a thermal protection system or a thermostat, which is currently off.

Output LED is defect or there is another regulator defect

Replace the regulator or take it to repair.

Outputs do not switch on as they should

Output is not activated

Activate the output by setting the relevant priority.

PV-plant does not provide sufficient power output

Check whether there is enough surplus energy available in respective phase wire or sum of phases L1 + L2 + L3 is positive,

depending on configured control mode.

Incorrectly set priorities or connected power values

Check the priority settings of your loads and connected power settings according to their power ratings.

Incorrect settings of some items in the Other settings tab

Check the settings in the Power offset field. Also check the CombiWATT production limit field, which should be low.

You cannot download firmware, even if you try repeatedly

Incorrect or corrupted *.scf file

Load only original regulator firmware for the WATTrouter Mx device.

Communication errors

Make sure that there are no problems with the connection of the regulator to PC, or in the PC alone (viruses etc.).

Regulator failure/defect

Replace the regulator or take it to repair.

Flashing red LED

The system detected error status

Follow instructions in the LED statuses chapter.

When the available surplus energy is decreased, the SSR output with higher priority is switched off earlier than the relay output with lower priority

This is normal

Relay outputs have always longer delay when in the process of disconnecting. In order to make sure that energy from the power grid is not drawn unnecessarily, all connected proportional outputs with higher priority may be disconnected earlier than the relay outputs with lower priority.

CombiWATT function runs even if PV-plant produces power

This is normal

CombiWATT will be initiated even if during the time specified in the CombiWATT delay time field, no production is detected at any phase wire, which may occur if the PV-plant produces small amount of energy or if loads with large power consumption operate for long time and consume all available surplus energy. If you want to eliminate this behavior, increase the value in the CombiWATT delay time field.

Solid state relay (SSR) does not switch on

SSR is not connected correctly

Check for proper terminal connection and observe polarity of SSR control anodes.

Incompatible relay

Always use a SSR with zero cross switch and minimum DC control voltage of 4VDC.

Regulator failure/defect

Replace the regulator or take it to repair.

SSR failure/defect

Replace the SSR.

Data in statistics don't correspond with reality

This is normal

The data are indicative only; the device does not have accurate data from utility/billing meters. Furthermore, the device may be configured improperly, i.e. does not evaluate the same as your utility meter does.

Statistics suddenly erased

This is normal

There was a date change in the regulator or power failure during writing the history into EEPROM. Statistics on SD card should be

fine.

SC-Gateway module is inserted in the regulator, but neither Link LED nor PWR LED works

Incorrect inserting of module

Remove and insert module once again based on installation module manual.

Regulator or module failure/defect

Replace the module or regulator or take them to repair.

Wireless peripheral can’t be registered, even after longer period while connected. Window Add wireless station is not displayed.

Station out of signal range

Test the wireless peripheral so it is placed temporary closer to the regulator. Once this time it is detected, there is necessary to extend signal range with signal repeater. Consult this problem with technical support.

Station is incompatible

It is different type of wireless peripheral, which is not compatible with SC-Gateway module.

Station is defective

Follow the installation manual for the wireless peripheral.

SC-Gateway module does not react

Reset the regulator and wait about 1 minute. Then repeat the network registration procedure.

SC-Gateway module failure/defective

Replace the module or take it to repair.

Wireless station does not switch or switches incorrectly

Station out of signal range

Station is defective

Follow the station manual

SC-Gateway module does not react

MA INTENANCE AN D R EPA I RS

The WATTrouter Mx devices have been designed as maintenance-free units, provided that they were configured and fitted according to instructions specified in this manual. We recommend inspecting the operation of the entire system at regular intervals (at least once in a month, for example, when inspecting the status of the PV-plant). Focus mainly on the load switching process and heat dissipation.

Should you discover a defect which cannot be repaired according to instructions specified in the Troubleshooting chapter, contact your distributor (applies both to warranty and post warranty repairs).

Defect on current sensing module is very improbable. In case of a defective regulator, you can send only the regulator for repair or replacement. The current sensing module may still remain fitted without the regulator. Even if electric currents flow through measuring coils, the module will not be damaged.

Never attempt to repair your device by yourself! If you do so, you are putting yourself at risk of electric shock. Further, your entire warranty will be void!
