Controller and VFS sensor have to have the same ground potential. The VFS sensor has a functional earth connector (PELV). The PE-connector of the controller has to be connected to the pipe system near the sensor.

Caution

C.2. - Electrical connection

Danger

Before working on the unit, switch off the power supply and secure it against being switched on again! Check for the absence of power! Electrical connections may only be made by a specialist and in compliance with the applicable regulations. Do not use the controller if the housing shows visible damage.

Caution

Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand side.

Caution

The customer must provide an all-pole disconnecting device, e.g. a heating emergency switch.

Caution

The cables being connected to the unit must not be stripped by more than 55mm, and the cable jacket must reach into the housing just to the other side of the strain relief.

Relays R1 and R2 are only suitable for standard pumps (20-120VA). These pumps are speed controlled by the controller. Due to the internal wiring, even when switched off residual energy is present in R1 and R2. Do not use R1 and R2 for valves, contactors or other devices with low power consumption.

Achtung

1. Select necessary program/hydraulics (s. „D.3. - Hydraulic variants / Schemes / Systems“ on page 10)

2. Remove terminal connection cover (s. „D.2. - Terminal connection diagram“ on page 9)

3. Strip cables by 55mmmax., insert, ﬁ t the strain relief de- vices, strip the last 8-9mm of the wires (Fig. „C.2.1.“)

4. Open the terminals using a suitable screwdriver (Fig. „C.2.2.“) and make electrical connections on the controller

5. Reﬁ t terminal connection cover and fasten screw.

6. Switch on mains voltage and place controller in operation.

C.2.1.

C.2.2.

Installation

The temperature sensor cables must be routed separately from mains voltage cables, and must not, for example, be routed in the same cable duct!

Caution

The controller operates with Pt1000 temperature sensors which are accurate to the degree, thus ensuring optimal control of system functions.

Caution

If desired the sensor cables can be extended to a maximum of 30m using a cable with a cross-section of at least 0.75mm². Make sure that there is no contact resistance! Position the sensor precisely in the area to be measured! Only use immersion, pipe-mounted or ﬂ at-mounted sensor suitable for the speciﬁ c area of application with the appropriate permissible temperature range.

Connect the VFS sensors with the matching jacks. To prevent damage to the Direct Sensors it is highly recommended to install them in to the return.

When installing the Vortex Flow Sensors (VFS), observe the correct ﬂ ow direction!

Instructions for clamps:

1. Insert screw driver into the upper hole. Push the lock

clamp inside down.

Keep the screw driver in this position.

2. Insert cable into the lower opening.

Operation

E.2 Commissioning help

the switch outputs with the consumers connected, and to check the sensor values for plausibility. Then switch on automatic mode.

The ﬁ rst time the controller is turned on and after the language and time are set, a query appears as to whether you want to parametrise the controller using the commissioning help or not. The commissioning help can also be terminated or called up again at any time in the special functions menu. The commissioning help guides you through the necessary basic settings in the correct order, and provides brief descriptions of each parameter in the display. Pressing the “esc” key takes you back to the previous value so you can look at the selected setting again or adjust it if desired. Pressing the “esc“ more than once takes you back step by step to the selection mode, thus cancelling the commissioning help. Finally, menu „3.2. - Manual“ on page 14 should be used to test

Caution

Observe the explanations for the the individual parameters on the following pages, and check whether further settings are necessary for your application.

3. - Operating modes

In menu “3. Operating modes” the controller can either be placed in automatic mode, switched off, or placed in a manual operating mode.

The menu is closed by pressing “esc” or selecting “Exit operating modes”.

Automatic mode is the normal operating mode of the controller. Only automatic mode provides proper controller function taking into account the current temperatures and the parameters that have been set! After an interruption of the mains voltage the controller automatically returns to the last operating mode selected!

3.1. - Automatic

Operating modes

3.2. - Manual

The relay and thus the connected consumer are switched on and off by pressing a key, with no regard to the current temperatures and the parameters which have been set. The measured temperatures are also shown to provide an overview and function control.

Danger

When operating mode “Manual” is activated, the current temperatures and the selected parameters are no longer considered. There is a danger of scalding or serious damage to the system. The operating mode “Manual” may only be used by specialists for brief function tests or during commissioning!

3.3. - Off

When the operating mode “Off” is activated, all controller functions are switched off. This can lead, for example, to overheating on the solar collector or other system components. The measured temperatures are sstill displayed to provide an overview.

Caution

3.4. - Fill system

This special operating mode is intended only for the ﬁ lling procedure for a special “Drain Master System” with a ﬁ ll level contact parallel to collector sensor S1. The instructions on the display must be followed when ﬁ lling the system. Be sure to terminate the function when ﬁ nished!

Caution

The following pages contain generally valid descriptions for the settings. Enumerations may vary .

Caution

4. - Settings

The necessary basic settings required for the control function are made in menu “5. Settings”.

4.1. - Tmin S8

Enable/start temperature at sensor 8:

If this value is exceeded at the applicable sensor X and the other conditions are also met, then the controller switches on the associated pump and/or valve. If the temperature at the sensor drops below this value by 5°C, then the pump and/or the valve are switched off again.

Settings range : 0°C to 99 °C / Default setting: 20°C

Caution

This does not under any circumstances replace the safety facilities to be provided by the customer!

The menu is closed by pressing “esc” or selecting “Exit settings”.

Settings

4.2. - Priority S (X) Priority of Storages X

This determines the order, in which the storages are charged.

Settings range: 1-4

4.3. - Tmax S (X)

Switch-off temperature at sensor (X)

If this value is exceeded at the applicable sensor (X), the controller switches the associated pump and/or valve off. If the temperature falls below this value again and the other conditions are also met, then the controller switches the pump and/or valve on again.

Settings range: 0°C to 99 °C / Default setting: 60°C

Danger

Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must be provided by the customer!

If the set temperature difference is too small, this may result in ineffective operation, depending on the system and sensor positions.Special switching conditions apply for speed control (see „6.2. - Speed control“ on page

19)!

Caution

4.4. - ∆ T Solar P (1-4)

Switch- on/switch-off temperature difference for sensor X :

If this temperature difference between the reference sensors is exceeded and the other conditions are also met, then the controller switches the applicable relay on. When the temperature drops to T Off, then the relay is switched off.

Settings range: ΔT On from 6°C to 20°C / ΔT Off from 2°C to 19°C Default setting: ΔT 10°C / ΔT-Off 5°C

Settings

4.5. - T-priority

Temperature threshold for absolute priority

In systems with multiple storage tanks, charging of the lower-priority storage tank will never take place until this set temperature setpoint at the storage tank sensor of the higher-priority storage tank is exceeded.

Setting range: from 0°C to 90°C/default setting: 40°C

4.6. - Loading time Interruption of charging into the lower priority storage tank

The charging of the lower-priority storage tank is interrupted after the settable time in order to check whether the collector has reached a temperature level that allows charging in the higher-priority storage tank. If so, the priority storage tank is charged. If not, the increase is measured (see „4.7. - Increase“), to check if charging of the priority storage tank will be possible shortly.

Setting range: from 1 to 90 minutes/default setting: 20 minutes

4.7. - Increase Extension of the charging pause due to temperature increase in the collector

For precise setting of the charging priorities for systems with multiple storage tanks, the necessary temperature increase of the collector at which the interruption of the charging into the lower-priority storage tank is extended by one minute is set here. The interruption is extended because the temperature increase of the collector is expected to enable charging in the higherpriority storage tank soon. As soon as T conditions are met, the priority storage tank is charged. If the rise in temperature falls below the set value, then the charging of the lower-priority storage tank is enabled again.

Setting range: from 1°C to 10°C/default setting: 3°C

4.8. - Pump delay

Waiting time before activation of additional pumps

This function prevents multiple primary pumps from being switched on simultanously. When a primary pump is activated, no additional pump can be activated for this time span. After this waiting period has passed, and when the conditions are met, another pump can be switched on.

Settings range: 10 to 200 seconds / Default: 10 seconds

Menu „6. - Protective functions“ can be used to activate and set various protective functions.

The menu is closed by pressing “esc” or selecting “Exit”.

Protections

5. - Protections / Protective functions

Caution

This does not under any circumstances replace the safety facilities to be provided by the customer!

5.1. - System protection

Highest Priority Protection

System protection prevents overheating of system components by automatic shutdown of the solar pump. If “SProt Ton” is exceeded at the collector, the pump is switched off and stays off. The pump is activated again when the temperature drops below “SProt TOff”.

System protection - Settings range: ON / OFF / Default setting: On SP T on - Settings range: 60 °C to 150 °C / Default setting: 120 °C SP T off - Settings range: 50 °C to T on minus 5 °C / Default setting: 115 °C

Caution

When system protection is on, the temperature in the idle collector will be very high, thus the pressure in the system will rise and can damage your system. Pay close attention to the instructions of the system manufacturer.

5.2. - Collector protection

Collector protection prevents overheating of the collector. The pump is switched on to transfer heat from the collector to the storage tank. If “CP Ton” is exceeded at the collector sensor, the pump is switched on until the temperature reaches “CP Toff” or the temperature “CP Tmax storage” is exceeded in the storage.

Collectorprotection - Settings range: On / Off / Default setting: Off CP T on - Settings range: 60°C to 150°C / Default setting: 110°C CP T off - Settings range: 50°C to T on minus 5°C / Default setting: 100°C CP Storage S(x) Max - Settings range: 0°C to 140°C / Default setting: 90°C

Danger

When collector protection is active, the storage is heated up to „CP Storage S(x) Max“ beyond Tmax S2 (see „4.2. - Tmax S1“ on page 15) which can result in scalding and system damage.

In hydraulic systems with solar when the recooling function is activated excess energy from the storage tank is fed back into the collector. This only takes place if the temperature in the storage tank is higher than the value “Recool Tsetpoint” and the collector is at least 20°C cooler than the storage tank and before the storage tank temperature has dropped below the value “Recool Tsetpoint” (Hysteresis 10°C). In systems with two storage tanks the setting applies to both storage tanks.

Recooling - Settings range: On, Off / Default setting: Off Rückkühl Tsoll - Settings range: 0°C to 99°C / Default setting: 70°C

5.3. - Recooling

Caution

Energy is lost via the collector when Recooling is active! Recooling should only be activated as exception, when little or no heat is used, e.g. when the residents are on vacations.

System protection has a higher priority than collector protection. Even when the switch on conditions for collector protection are present, the solar pump will be switched off when SP T on is reached.

Caution

This function causes energy to be lost via the collector! It is normally not activated for solar systems with antifreeze. Observe the operating instructions for the other system components!

Protective functions

A two-stage frost protection function can be activated. In stage 1 the controller switches the pump on for 1 minute every hour if the collector temperature drops below the set value “Frost stage 1”. If the collector temperature drops further to the set value “Frost stage 2” the controller switches the pump on continuously. If the collector temperature then exceeds the value “Frost stage 2” by 2°C, then the pump switches off again.

Frost protection setting range: on, off/default setting: off Frost stage 1 setting range: from -25°C to 10°C or off/default setting: 7°C Frost stage 2 setting range: from -25°C to 8°C (must be lower than stage 1) / default setting: 5°C

5.4. - Frost protection

If the seizing protection is activated, the controller switches the relay in question and the connected consumer on every day at 12:00 (setting “daily”) or weekly on Sundays at 12:00 (setting “weekly”) for 5 seconds in order to prevent the pump and/or the valve from sticking after an extended stationary period.

Setting range: daily, weekly, off/default setting: Off

5.5. - Seizing protection

5.6. - Collector alarm

If this temperature is exceeded at the collector sensor when the solar pump is on a warning or error message is triggered. A warning message is shown in the display.

Collector alarm - Settings range: Off, On / Default setting: Off Collector alarm - Settings range: 60 to 299 / Default setting: 115°C Delay - Settings range: 1 to 60 Minuten / Default setting: 1

6.2. - Speed control

6.2.1. - Variant

6.2.2. - Type of pump

The following speed variants are available here:

Off: There is no speed control. The connected pump is only switched on or off with full speed. Variant V1: After the purging time the controller switches to the set max. speed. If the temperature difference T between

the reference sensors (collector and storage tank) is less than the set value, then the speed is decreased by one stage after the control time elapses. If the temperature difference between the reference sensors is greater than the set value, then the speed is increased by one stage after the control time elapses. If the controller has adjusted the speed of the pump down to the smallest stage and the T between the reference sensors is T off, the pump is switched off. Variant V2: After the purging time the controller switches to the set min. speed. If the temperature difference T between the reference sensors (collector and storage tank) is greater than the set value, then the speed is increased by one stage after the control time elapses. If the temperature difference T between the reference sensors is below the set value, then the speed is decreased by one stage after the control time elapses. If the controller has adjusted the speed of the pump down to the smallest stage and the T between the reference sensors is Toff, the pump is switched off. Variant V3: After the purging time the controller switches to the set min. speed. If the temperature at the reference sensor (collector) is greater than the setpoint to be set subsequently, then the speed is increased by one stage after the control time expires. If the temperature at the reference sensor (collector) is less than the setpoint to be set subsequently, then the speed is decreased by one stage after the control time expires.

Setting range: V1,V2,V3, off/default setting: off

Variant V4:

When the primary storage is loaded, speed control works as in V3. When the secondary storage is loaded, speed control works as in V2.

Settings range: V1,V2,V3, Off / Default: Off

The type of speed controlled pump must be entered here.

Standard: Speed control for standard pumps. 0-10V: Speed control of e.g. High efﬁ cency pumps by 0-10V signal. PWM: Speed control of e.g. High efﬁ cency pumps by PWM signal.

This function should only be activated by a specialist. Depending on the pump and pump stage used, the minimum speed should not be set too low, because otherwise the pump or the system may be damaged. The information provided by the relevant manufacturer must also be observed! If in doubt, the min. speed and the pump stage should generally be set to high rather than too low.

Caution

The anti-Legionella function is switched off at delivery. Whenever heating-up has been carried out with the anti-Legionella function switched on, an information message with the date appears on the display.

During the anti-Legionella function the storage tank is heated up over the set value “Tmax S(X)”, which can lead to scalding and damage to the system.

Danger

This anti-Legionella function does not provide complete protection against Legionella, because the controller is dependent on sufﬁ cient energy being fed in, and it is not possible to monitor the temperatures in the entire range of the storage tanks and the connected piping system. To provide complete protection against Legionella bacteria, it must be ensured that the temperature is raised to the necessary temperature, and at the same time there must be water circulation in the storage tank and piping system by means of other additional energy sources and external control units.

Special functions

6.18. - Heat quantity Constant ﬂ ow

When the heat meter mode „Flow rate“ is selected, an approximated heat quantity is calculated using the values the user has to enter. These are type of glycol/AntiFreeze, glycol portion and ﬂ ow rate. These values are put into correlation with the temperature data of collector sensor and storage sensor. If necessary a correction value for T can be set: Since for the heat meter the collector and the storage temperature are used, a difference to the ﬂ ow respectively return ﬂ ow temperature can be compensated by changing Offset T accordingly. Example: Displayed collector temp. 40°C, measured ﬂ ow temperature 39°C, displayed storage temperature 30°C, measured return tem- perature 31°C = results in a correction value of -20% (displayed T 10K, real T 8K = -20% correction)

VFS

When the mode VFS is selected, the direct sensor with combined temperature and ﬂ ow measurement is used.

Caution

The heat quantity measured in the mode “Flow rate” is a calculated approximation for function control of the system.

This determines the ﬂ ow rate in litres per minute that is used for the calcualtion of the heat quantity.

Settings range: 0-100 l/min / Default setting: 5 l/min

6.18.6. - Offset ∆ T

Correction value for temperature difference

Since for the heat meter the collector and the storage temperature are used, a difference to the ﬂ ow respectively return ﬂ ow temperature can be compensated by changing Offset T accordingly. Example: Displayed collector temp. 40°C, measured ﬂ ow temperature 39°C, displayed storage temperature 30°C, measured return tem- perature 31°C = results in a correction value of -20% (displayed T 10K, real T 8K = -20% correction)

Settings range: -50 to +50% / Default setting: 0%

6.18.7. - VFS (X)

Caution

To prevent damage to the VFS sensor it is strongly recommended to install it into the return ﬂ ow. If it is necessary to install in the ﬂ ow, it is imperative not to exceed the maximum temperatures of the sensor! (0° C to 100°C and

-25°C to 120°C short term)

Special functions

6.19. - Sensor calibration

Caution

May only be started by a specialist during commissioning! Incorrect settings may cause malfunctions.

Starting the commissioning help guides you in the correct order through the basic settings necessary for commissioning, and provides brief descriptions of each parameter in the display. Pressing the “esc” key takes you back to the previous value so you can look at the selected setting again or adjust it if desired. Pressing the “esc” more than once takes you back to the selection mode, thus cancelling the commissioning help.

6.20. - Commissioning

May only be started by a specialist during commissioning! Observe the explanations for the the individual parameters in these instructions, and check whether further settings are necessary for your application.

Deviations in the temperature values displayed, for example due to cables which are to long or sensors which are not positioned optimally, can be compensated for manually here. The settings can be made for each individual sensor in steps of 0.8°C (temperature) resp. 0.2% of the measuring range of the VFS / RPS sensor (ﬂ ow rate / pressure) per step.

Offset Sensor Settings range: -100 ... +100 / Default setting: 0

Caution

All of the settings that have been made can be reset, thus returning the controller to its delivery state.

6.21. - Factory settings

The entire parametrisation, analyses, etc. of the controller will be lost irrevocably. The controller must then be commissioned once again.

6.22.6. - Unmount

To prevent damage to the SD card or loss of data, please unmount the card before removing it from the controller.

With some solar systems, especially with vacuum tube collectors, it may occur that the measurement value acquisition at the collector sensor occurs too slowly or too inaccurately because the sensor is often not at the hottest location. When the start help is activated the following sequence is carried out: If the temperature at the collector sensor increases by the value speciﬁ ed under “Increase” within one minute, then the solar pump is switched on for the set “Purging time” so that the medium to be measured can be moved to the collector sensor. If this still does not result in a normal switch-on condition, then the start help function is subject to a 5-minute lockout time.

Start help setting range: on, off/default setting: off Purging time setting range: 2 ... 30 sec./default setting: 5 sec.

Increase setting range: 1°C....10°C/default setting: 3°C/min.

Malfunctions

If the controller detects a malfunction, the red light ﬂ ashes and the warning symbol also appears in the display. If the error is no longer present, the warning symbol changes to an info symbol and the red light no longer ﬂ ashes. To obtain more detailed information on the error, press the key under the warning or info symbol.

Possible error messages: Notes for the specialist:

Sensor defective Means that either the sensor, the sensor input at the controller or the connecting cable is/

was defective. (Resistance table see „B.2. - Temperature resistance table for Pt1000 sensors“ on page 5)

Collector alarm Means that the collector has fallen/fell below the temperature set under menu „5.6. - Collec-

tor alarm“ on page 18

Restart Means that the controller was restarted, for example due to a power failure. Check the

date&time!

Time & Date This message appears automatically after a mains failure because the time&date have to

be checked, and reset if necessary.

System protection Collector temperature overshot the set temperature, the solar pump was switched OFF to

prevent damage due to excessive heat.

Collector protection Collector temperature overshot the set temperature, the solar pump was switched ON to

prevent damage to the collector due to excessive heat.

Recooling Excessive heat was radiated via the collector to protect the system.

Frost protection The solar pump was switched on to prevent damage to the collector.

Frequent on / off When the solar pump is switched off and on more than 5 times in 5 minutes, this message

is displayed.

No ﬂ ow This message is displayed when the solar pump is running and for 5 minutes the dT >=50°C

Pressure: Failure This message is displayed when pressure monitoring is activated and the limits Pmin or

Pmax are exceeded.

SD card error This message is displayed when an SD card is detected, but cannot be read or written on.

Danger

Do not try to deal with this yourself. Consult a specialist in the event of an error!

Malfunctions and Maintenance

If the mains voltage is switched on and the controller still does not function or display anything, then the internal device fuse may be defective. In that case, open the device as described under C, remove the old fuse and check it. Exchange the defective fuse for a new one, locate the external source of the error (e.g. pump) and exchange it. Then ﬁ rst recommission the control- ler and check the function of the switch outputs in manual mode as described under „3.2. - Manual“ on page 14

Danger

Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the power supply and secure it against being switched on again! Check for the absence of power!

Only use the supplied spare fuses or fuses of the same design with the following speciﬁ cations: T2A / 250V .

Z.2 Replacing the fuse

Z.2.1

Performing maintenance:

- Check the date and time (see „6.24. - Time and date“ on page 34)

- Assess/check plausibility of analyses (see „2. - Statistics“ on page 13)

- Check the error memory (see „2.4. - Message log“ on page 13)

- Verify/check plausibility of the current measurement values (see „1. - Measurement values“ on page 13)

- Check the switch outputs/consumers in manual mode (see „3.2. - Manual“ on page 14)

- Possibly optimise the parameter settings

Z.3 Maintenance

Caution

In the course of the general annual maintenance of your heating system you should also have the functions of the controller checked by a specialist and have the settings optimised if necessary.

Fuses T2A / 250V

The service values (see „8. - Service values“ on page 36) include not only current measurement values and operating states, but also all of the settings for the controller. Save the service values at least once after commissioning has been successfully completed (see „6.22.4. - Save conﬁ guration“ on page 34).

In the event of uncertainty as to the control response or malfunctions the service values are a proven and successful method for remote diagnosis. Save the service values (see „8. - Service values“ on page 36.) at the time that the suspected malfunction occurs. Send the service value table with a brief description of the error to the specialist or manufacturer.

In programs with pools, the charging of the pool, e.g. for winter operation, can be switched off using a simple function. To do this, simply press and hold the “esc” key down for several seconds on the diagram/overview screen. A message appears on the display as soon as the pool is switched off or when the pool is switched on again.

To protect against loss of data, record any analyses and data that are particularly important to you (see 2.) at regular intervals.
