1.5 Glossary of used terms and conceptions

In case of unfamiliar terms in the document, you can find the explanation here.

ALTERNATIVE SOURCE: The heat source is used for systems with solar collectors,

fireplaces and wood stoves when we either do not have a heat source on hand at any moment or an automatic switch through the signal from the controller of the device (i.e. in a wood stove) is not possible.

ADDITIONAL SOURCE: The external heat source found alongside the device (i.e.

oil/gas/pellet/external heater furnace) or internal heat source (electrical flow heater) which is factory integrated in certain types of devices. The spare or additional source can be used as “assistance” to the device under the so-called bivalent point when the capacity of the device does not suffice for maintaining the desired temperature. It can be used alongside the device alternatively (the either-or system) – the switch is automatic.

BACKUP SOURCE: A function, which turns on the selected additional source in the event

of an error or a remote shutdown. The device operates in antifreeze mode. The device will turn off following the confirmation of an error or interrupt signal from the remote off.

The flow heater which is installed in the device and turns on in the case of device

malfunction (in the so-called antifreeze programme). This ensures temporary operation for bridging the time until an authorised person from the service company arrives and corrects the error.

HEATING WATER: The liquid which flows inside the heating system (pipelines, floor, wall

and radiator heating). DHW: The water intended for sanitary use (cleaning, showering, washing ...). HEAT PUMP (HP): The device which takes energy from the environment, uses electric

energy to drive the device and releases heat from space heating and DHW. In the text

below the term ‘device’ will be used for the heat pump. HW: The device takes heat from the earth. AW: The device takes heat from the air. WW: The device takes heat from groundwater. Parameter NORMAL: The desired temperature of heating in the Normal mode of

operation. Parameter ECO: Lowering the desired temperature in the Eco mode of operation. Parameter COMFORT: Raising the desired temperature in the Comfort mode of operation. Operator: Is a natural or legal person who has real control over the technical operation of

the products and equipment covered in the directive (EU) No. 517/2014; a member state

can impose operator obligations on the owner in clearly defined and specific cases.

2 General facts about the heat pump

2.1 What is a heat pump

A heat pump is a device which uses renewable energy sources (air, earth and water) and enables us economical and ecologically friendly heating and cooling of the building as well as heating DHW. Whether it is intended for internal or external installation depends on the device itself. Heat pump operation:

HEAT SOURCE

HEAT PUMP

HEATING SYSTEM

The device takes heat from the environment or source (groundwater, earth, air) and transfers it to the water in the heating system. This is achieved with the process of evaporating the coolant in the evaporator which is a heat exchanger especially designed for this task. This coolant is compressed in the compressor in the next circuit to a higher pressure which makes the temperature of the coolant rise to a temperature higher than the temperature of the heated water. This coolant then condenses in the water-cooled condenser where the heat taken from ground water/earth/air and electrical energy needed for the operation of the compressor are transmitted to the heating water. The heating water can be heated up to 65 degrees Celsius and more through this process (depending on the operating conditions of the device); this makes the devices suitable for renovating older heating systems.

4 Quick settings

NOTE

The parameters of the TERMOTRONIC controller were set according to project documentation of the heating/cooling system, recommendations of the manufacturer of the device and your requests by the authorised contractor for commissions at commission. At handover, the contractor for commissions is obliged to thoroughly present you with the possible ways of the device’s operation and explain the setting modes of the parameters important for the user.

The basic function of the device is space heating and heating the DHW . The controller of the device calculates the optimal needed temperature of the heating water to achieve the desired air temperature of the room in dependence on the outside temperature.

Setting the temperature of heating/cooling The temperature in the heated/cooled room is controlled in two stages, by setting the temperature:

1. of the room with the spatial corrector or thermostat and

2. the heating/cooling water in the accumulator and heating/cooling circuits on the controller TERMOTRONIC.

NOTE

In case despite the change in the setting of the temperature with the spatial corrector or thermostat after a longer period of operation of the heating/cooling circuit (in floor heating this could last up to 4 days) the desired room temperature was not achieved, check the heating water temperature settings. For settings see chapter 4.2.

4.1.1 Setting room temperature with the spatial corrector KT-2

The spatial corrector KT-2 enables an advanced and very easy settings of room temperature and basic functions of the device.

By pressing the key or the display displays the currently set room temperature. The temperature is marked by an orange border. By pressing the key or again you adjust the desired room temperature. You confirm the change by pressing the OK button, although, the change auto-saves in 8 seconds.

C/W ALL I D8-PV Cooling Silent mode >Language EN <

Page 16

6.2018

NOTE

The space corrector influences the whole heating circuit and not the temperature of the individual room. The desired room temperature where the spatial corrector is located in the reference temperature for all other rooms of the heating circuit controlled by this spatial corrector. Before raising the temperature of heated water or the desired room temperature on the spatial corrector make sure the valves on the heat sources in the room where it is too cold for you, are completely or sufficiently opened. If the temperature of other rooms is too high or too low open or close the valves for floor heating or radiators where the deviations from the desired temperature take place.

NOTE

For maintaining the correct operation of the heating system you have to choose a suitable operating mode - winter (heating and DHW) or summer (DHW and cooling only in certain models). For choosing the mode see chapter4.3.

NOTE

A detailed description of the settings and additional functions (weather report, DHW, operating mode, information about the state of the device ...) see the manual for the spatial corrector KT-2.

4.1.2 Setting room temperature with the spatial corrector KT-1

The spatial corrector KT-1 enables basic settings of room temperature.

By pressing the key or the LED display displays the currently set desired room temperature. By pressing the key or again you adjust the desired room temperature. By pressing the keys you adjust the values by 0.5 °C. The change is confirmed automatically.

Quick setting: By pressing and holding the key the temperature setting changes in steps of 1 °C.

NOTE

The space corrector influences the whole heating circuit and not the temperature of the individual room. The desired room temperature where the spatial corrector is located in the reference temperature for all other rooms of the heating circuit controlled by this spatial corrector. Before raising the temperature of heated water or the desired room temperature on the spatial corrector make sure the valves on the heat sources in the room where it is too cold for you, are completely or sufficiently opened. If the temperature of other rooms is too high or too low open or close the valves for floor heating or radiators in the rooms where the deviations from the desired temperature take place.

NOTE

You can find a detailed description of settings and additional functions in the manual for the spatial corrector KT-1.

Page 17

6.2018

4.1.3 Setting the room temperature with a room thermostat

For setting the room temperature with a room thermostat consult the manual which come with the thermostat or consult the installer.

NOTE

In case the thermostat is turned on all this time and the heating system does not heat/cool the space to the desired temperature, check the settings of temperatures of the heating system on the device.

NOTE

For choosing the function of heating or cooling an appropriate thermostat has to be installed which allows both functions.

NOTE

4.2 Setting the temperature of heating water

Upon start-up the control of the heating water temperature of your heating system was set to Heating curve mode which ensures the most energy efficient operation of the device. In case the automatically calculated temperature of the heating water (in accordance with the external temperature) is insufficient for ensuring the comfort of living in the rooms, the temperature of the heated water can quickly be raised or lowered by changing the parameter of cooler/hotter (C/W). The values of the parameter C/W are adjusted in the menus 1. Circuit 2. Circuit 3. Circuit or

4. Circuit depending on which temperature you want to change. If you want to change (raise/lower) the temperature of the heated water for the whole building or heating system, change the parameter C/W in the menu Heating.

NOTE

Upon start-up the heating water temperature control was set to Heating curve mode. The authorised contractor for commissioning noted your heating water settings of the heating circuits into chapter 11.

By setting the parameter C/W you set the number of temperature steps (one temperature step equals 1 °C) for which you want to raise or lower the temperature of heated water. You perform the settings in the following steps:

Press key (MENU) in the basic menu.

In the user interface, use the key and choose menu 1. Circuit and press the key

(ENTER).

Page 18

6.2018

The first line has the parameter C/W

selected.

To set the parameter press key (ENTER).

* * appear along the chosen parameter. The keys and change the value of the

parameter C/W. This raises or lowers the temperature of heated water.

Each pressing of the key raises/ lowers the temperature of the heating circle for one temperature step (<, >). To confirm the settings press key

(ENTER).

After conformation the controller calculates the new temperature setting for the heating circuit or heated water according to the external temperature (in case of weather control). For returning to the basic view press the key

(MENU) twice.

For advanced changing the temperature of the heated water control mode of the heating system see chapter 5.1.

NOTE

The temperature of heated water can be raised or lowered for no more than

four temperature steps.

The heating and individual circuits settings are separated from the cooling, this

is why all settings for heating remain unchanged with the change of the mode into cooling. The same is true for parameter settings in the menu Cooling,

1. Circuit, 2. Circuit, 3. Circuit, 4. Circuit and Heating, which are separated so as to maintain all settings when changing the heating Mode (winter/summer).

For heating curve you can choose various temperature modes of operation

with setting daily and weekly schedules. See chapter5.4.

NOTE In case of radiator heating for a significant change, change the parameter C/W for 2 or 3 temperature steps at once but only for 1 temperature step in case of floor heating. Please note that the responsiveness of the heating system in the case of radiator heating is quicker than in the case of floor heating. By changing the parameter C/W several hours can pass (in the case of floor heating) before the heating system responds properly and you can feel the change of the adjustment.

4.3 Setting the temperature of DHW

Once the temperature of the DHW falls below the set temperature minus the parameter Hysteresis (example: DHW setting is 50,0 °C, Hysteresis setting is 5,0 °C  DHW heating will start at 44,9 °C), the controller switches the device from space heating to heating DHW. Heating DHW has priority over other modes of operation. Setting the temperature of DHW is performed in the following steps:

Press key (MENU) in the basic menu.

In the user menu choose the menu DHW with the key and press the key (ENTER).

In the menu DHW in the first line the parameter DHW is chosen. To set the parameter press key

(ENTER).

* * appear along the chosen parameter. The keys and change the value of the parameter DHW. This raises or lowers the

temperature of DHW.

To confirm the settings press key (ENTER).

Next to the set parameter you can again find the symbols > <.

For returning to the basic view press the key

(MENU) twice.

NOTE

The actual reached temperature of heated water in the DHW depends on the adequacy of the DHW, pipelines, flow and ventilation of the system.

NOTE

For controlling the temperature settings of DHW in the tank you can set different modes of operation (ECO, Comfort), daily and weekly schedules. See chapter 5.4.

4.4 Changing the operational mode - winter/summer mode

The mode of operation - winter or summer, is chosen according to season. In the time when you do not need heating or want to cool the rooms, switch to summer operating mode. In case heating is needed, switch to winter mode. The choice can be automatic or manual.

NOTE

If you do not switch into the summer mode operation in the summer, this can result in higher energy consumption. The operational costs will be increased for two reasons:

The main circulation pump will switch on from time to time to check whether

the need for heating has arisen.

The additional source could also be turned on (for the protection of the heating

system) if the temperature falls below a certain point, i.e. 12 °C – this depends on the start-up settings.

NOTE

The cooling function is only provided by reversible and WPG + passive models of the devices.

The function of the device according to the chosen mode of operation: Mode

NOTE

In the winter mode (heating and DHW) the heating system works only for heating the heating water of activated circles and DHW. By using the built-in external switch we can launch manual switch on/off of the cooling mode of the device.

4.4.1 Changing the operating mode

Changing the operation from winter to summer mode is performed in the following steps:

Press key (MENU) in the basic menu.

In the user interface, use the key and choose menu Mode.

To confirm the settings press key (ENTER).

For returning to the basic view press the key

(MENU) twice.

NOTE

Setting the AUTO mode allows an automatic switch of the operating mode after the external temperature at 9 PM is higher or lower than the temperature of the switch (12 °C) for 3 days. This setting can be changed with the parameter Temp. mode in the menu Mode.

4.5 Setting the cooling temperature

In the operating mode (Summer, AUTO) which enables cooling you can adjust the temperature of cold water for the cooling circuits. The controller only enables the mode of controlling the temperature of cold water with maintaining constant temperature.

NOTE For setting the cooling of the building the Summer or AUTO Mode must be chosen.

NOTE

If the installer set the parameter (371) in chapter 11 Buff. to constant, always make sure the Cooling menu in 1. Circuit, 2. Circuit, 3. Circuit or 4. Circuit has the parameter Normal set to a value at least equal to or lower than the value of the circuit with the lowest setting.

To confirm the settings press key (ENTER).

For returning to the basic view press the key

(MENU) twice.

NOTE

The cooling and individual circuits settings are separated from the heating, this

is why all settings for cooling remain unchanged with the change of the mode into heating.

In the case of floor, ceiling or wall cooling appropriate settings and protection

have to be ensured in order not to cause surface condensation.

For controlling the temperature settings of cooling water you can set different

temperature modes, daily and weekly schedules. See chapter 5.4.

The response of the cooling system in convector cooling is faster than in floor,

ceiling or wall cooling.

4.6 Switching on the additional heat source

In case the heating capacity of the device is not sufficient for covering thermal losses of the building under given weather conditions, you can increase the capacity by switching on the Additional source. The device has a Backup source, a flow electric water heater fitted as standard which can function as an additional heat source by activating the parameter Additional source. Basically, the controller is set to activate the additional source which operates parallel to the device if the external air temperature falls below -7 °C. This setting is set according to the building at commissioning and can be changed later. Before setting the parameter we advise consulting the contractor for commissioning.

NOTE

In case you would like to use an oil/gas/pellet furnace or external electric heater as auxiliary heat source, you have to ask the contractor for commissioning to perform the setting.

Activating the additional source manually is performed in the following steps:

In the first row, after switching on the Backup source, the main display will display the information about the status of the device Heating+AdHeater.

NOTE

From an economic standpoint we advise using the additional source only if necessary because using it means higher heating costs. This is why we recommend to switch the auxiliary heat source from constant back to Need when there is no more need for additional heating capacity.

4.7 Manual activation of the additional heat source

In case the device has a malfunction or heating with the device is not possible for whatever reason, we recommend activating the additional source- the flow electrical water heater which will take over the heating of the heating and DHW.

5.1 Heating settings

NOTE

When setting or changing the desired heating water temperature, check whether parameter 371 is set to constant, chapter 11. In this case the following values have to be set: Normal and Correction in the menus Heating and 1. Circuit have to be equal and higher than the setting of desired values in the mixing circuits (2. Circuit, 3. Circuit and 4. Circuit), if they are active. In case one of the circuits (2. Circuit, 3. Circuit or 4. Circuit) is direct, it can have the same setting as 1. Circuit.

NOTE

In mixing heating cycles, the controller uses the highest set or calculated temperature of heating cycles for calculating the needed temperature.

The heating temperature thus consists of the set or calculated temperature of heating cycles and factory parameter settings Avt. Corr.

In weather controlled heating you can set three parameters:

► Normal: With this parameter, you set the desired return heating water temperature at an

outside air temperature of -18 °C.

► Standby: With this parameter you set the desired temperature difference between the

current desired temperature of the Return and the temperature of the return when the heating of the heating circuit or device turns on again.

► Correction: With this parameter you set the incline of the weather controlled heating curve

outside temperature 15 °C. It is mainly important for transitional periods because the weather controlled heating curve can be too low at this time, depending on the building and desired comfort.

The parameters Normal, Standby and Correction can be changed to the desired values with keys

5.1.1 Heating water control mode

The controller of the device enables two ways of controlling the temperature of heating water at the exit of the device or the entry into individual heating circuits:

a) Heating Curve: Setting the desired temperature of heating water according to external

temperature.

b) Constant: The temperature of heating water is kept constant regardless of the external

temperature. The control mode of the heating water suitable for individual buildings depends on various factors such as the type of building, its size, make of heating system ...; this is why the control mode for heating water temperature is set by a qualified person at commission (the authorised contractor for commissions) nevertheless, you can change the setting later. The recommendation of the device’s manufacturer is, if acceptable from the standpoint of comfort, etc., to set the heating water control mode to heating curve; this is why the present document regards this setting as the default setting - the setting set at commission. Heating curve means a more efficient operation of the heating system because by with higher external temperature the desired temperature of heated water is lowered, which means a more efficient operation of the device; for more information, see section 5.1.2.

Control modes for heating water have to be set separately by type in menus:

Here it is necessary to take account the NOTE (chapter 5.1)! The method of adjustment is the same in all cases and is described on the example of heating curve in section 5.1.2 and for the example of control at constant temperature in section 5.1.3.

5.1.1.1 The change in heating control heating curve - constant temperature

You can switch the heating control from heating curve to control by maintaining constant temperature in the following manner:

Press key (MENU) in the basic menu.

Choose the menu Heating or use the key to choose the desired Circuit. To set the parameter press key (ENTER).

Choose the Heating curve parameter by pressing and press the (ENTER) key.

* * appear along the chosen parameter. By pressing the key adjust the value of the

Heating curve parameter into Const. temperature and confirm the settings by

pressing the key (ENTER).

For returning to the basic view press the key

(MENU) twice.

5.1.2 Weather controlled heating – heating curve

Weather controlled heating means water temperature in the heating system is adjusted to the current air temperature. The lower the outside temperature, the higher the heat of the buildingand as a result a higher temperature of heating water is needed in the heating bodies (floor, wall or radiator heating ...) to compensate for the losses.

The opposite is true in case of higher outside temperatures. In this case the heat losses are lower and a lower heating water temperature is needed in the heating bodies to compensate for the losses.

The weather controlled heating curve shows that the temperature of the return (heating water returning to the heat pump from heating bodies) depends on the temperature of air outside the building. The lower the external air temperature, the higher the calculated needed temperature of the return.

The weather controlled heating curve

The appropriate heating temperature setting is essential for ensuring the desired comfort. It depends on the characteristics of the house and heating bodies as well as the project temperature. The table below lists the recommended settings which can help you decide on the appropriate parameters of the weather controlled heating.

5.2 Operating mode

The controller of the device enables heating of the heating water/ cooling of the cooling water, heating/cooling of the circuits and DHW in four different operational modes:

Normal applies to heating/cooling. DHW applies to the heating of DHW. ECO. COMFORT.

These different ways of operation can later be used with setting timetables.

The parameter ECO is used for more economical operation. During hating the temperature of the heating water is reduced, during cooling the temperature of cooling water is increased. In this operating mode you will save on costs but at the expense of comfort. The parameter COMFORT is used for the operation which means greater comfort - a raising of heating water temperature for the set value in the heating mode; in the cooling mode it means the opposite - a lowering of cooling water temperature.

In case you want to change the entire system to ECO or COMFORT operation, you can perform the adjustment in the menu mode where you change the parameter Operation AUTO to Operation

ECO or Operation COMFORT.

5.3 Setting the cooling system

You turn on the cooling mode by entering the menu mode and changing the parameter mode Winter to mode Summer (see chapter 4.4).

To turn on the cooling according to schedule you have to set the operating schedule for

cooling in the menu Cooling. The display and settings of the Cooling menu are enabled

only if the conditions of the mode’s operation listed in the section 4.4 are met (chosen mode

+ reversible heat pump or passive cooling).

For setting the parameter Schedule see chapter 5.4.

5.3.1 Active cooling (only in reversible models)

Cooling can be set for every parameter described in the table below separately.

In case of active cooling we recommend the following cooling settings:

PARAMETER COOLING

Cooling, 1. Circuit, 2. Circuit, 3. Circuit, and 4. Circuit

Floor, wall, ceiling [°C] Convector heating [°C]

Normal

19,0–20,0 12,0–15,0

Standby

2,0 3,0–4,0

NOTE

In mixing heating circuits we adjust the adjustable temperature of the supply pipe; in direct heating circuits and on the device we adjust the temperature of the return.

NOTE

Active cooling works in the area set in the menu Cooling with the parameters T.out.max. - external temperature above which the active cooling can operate actively

and the parameter Min - external temperature until which the active cooling can operate.

Parameters T.out.min and max. For setting active cooling.

To set the parameter press key (ENTER).

T.out.min 20.0°C max 40.0°C

Min.Diff. 2.0°C Checking TP 2400

Page 33

6.2018

5.3.2 Passive cooling

NOTE

Passive cooling is only possible with devices of the WPG type.

Passive cooling uses the coolness of the groundwater or earth this is why we cannot set

the desired temperature of cooling water. Cooling is activated when at least one of the heating circuits is active.

Passive cooling will work if the difference between the supply and return temperature of the

source is higher than the parameter Min.diff. which is set in the Cooling menu. In case the temperature difference is smaller the pump turns on periodically for the time set in the parameter Checking TP and will operate for the set time in the parameter for for the period until the difference between the supply and return temperature of the source is higher than the one set with the parameter Min.diff. The submersible pump turns on periodically so that the controller can acquire information about the actual temperature of ground water from the sensors built into the device (source). Based on this information it checks whether passive cooling is possible or not.

The operating indicator of the circulation pump for passive cooling is the ► sign on the

display of the regulation.

NOTE

Passive cooling works in the area set in the menu Cooling with the parameters T.out. min - external temperature above which the passive cooling can operate actively and

the parameter Max - external temperature until which the passive cooling can operate.

Parameters T.out.min and max for setting active cooling.

To set the parameter press key (ENTER).

NOTE

Parameters for passive cooling must be set lower as the setting for active cooling!

5.4 Schedules

5.4.1 Operating mode

Every function (heating, cooling, 1. Circuit, 2. Circuit, 3. Circuit, 4. Circuit, DHW, pool, silent operation and circulation) can operate in several ways. Setting the operation mode for individual functions are performed in the schedule for this function. In heating, cooling, mixing circuits, heating of DHW and swimming pool heating there can be 4 different types of operation:

► OFF: Heating/cooling is disabled. ► HEA of COL: Operation in the heating or cooling mode (parameter Normal). ► ECO: In this mode the controller maintains the temperature which is lower by the value of

the ECO parameter than the set temperature in the parameter Normal. In case of cooling

the temperature set in this mode is higher by the value of the ECO parameter than the set

temperature in the parameter Normal. In this mode operation is more economical.

► COM: In this mode the controller maintains the temperature which is higher by the value of

the COM parameter than the set temperature in the parameter Normal. In case of cooling

the temperature set in this mode is lower by the value of the COM parameter than the set

temperature in the parameter Normal. In this mode operation is less economical,

depending on the setting it can also be more comfortable.

In circulation of DHW two operation settings are possible:

► OFF: Circulation pump is disabled. ► CIR: Circulation pump is truned on.

Devices of the WPLV type enable two additional operation modes set in the menu Mode with the parameter Silent mode:

► NRM: Normal operation in the heating or cooling mode. ► LOW: Lowered operation mode in the heating or cooling mode. Lower noise level but also

lower heating or cooling capacity.

5.4.2 Setting operation schedules

NOTE

The easiest way to set the timetable is via the web application for remote control Cloud (cloud.KRONOTERM.com). For the use of the web interface see Instructions for use

Web interface. The schedule enables daily settings of 6 operation mode switches. Below is a description of heating with an example of a daily schedule.

Heating is turned off (OFF) from 00:00 to 02:00.

ECO

Page 35

6.2018

The heating is turned on at 02:00 in the COMFORT mode (in this mode the temperature is higher than the temperature set in the parameter Normal by the COM parameter). The heating is turned on at 07:00 in the ECO mode (in this mode the temperature is lower than the temperature set in the parameter Normal by the ECO parameter). At 1:00 PM the operating mode switches to COMFORT. AT 5:00 MP the operating mode switches to Normal (the temperature set or calculated in the parameter Normal). At 9:00 PM the heating turns off (OFF).

You perform the settings in the following steps:

In the menus Heating, Cooling, Circuits, choose the parameter Schedule with the key . When

the symbols > < appear next to the parameter Schedule, press the key (ENTER).

The day blinks which the schedule refers to. Choose the day you would like to set the schedule by using

keys or . When you choose the day press the key (ENTER).

The time when the switch-over will be performed blinks. By pressing the key (ENTER) confirm you want to set the time. Symbols XXXXX start

blinking over the time. Set the desired time with the key of the switch-over (in 15 min). To confirm the set time press key (ENTER). The symbols

XXXXX stop blinking over the time.

By pressing you can access the field for choosing the mode of operation. This field starts

blinking. By pressing the key (ENTER) confirm you want to set the mode of operation. Symbols XXX start blinking over the operating mode. Use

keys or to choose the suitable mode of operation along the set time. To confirm the

operating mode press key (ENTER). Symbols XXX no longer blink over the operating mode.

NOTE

Once you have set the operating mode it continues to be used until a new one is set. I.e. if you set the heating to OFF on Monday and you do not set anything for the following days, the heating will be OFF for all the following days as well because there was no change of operation mode.

The alternative source function is used for using the heat from the solar collectors (SSE) or for using heat from the biomass DHW s. All settings for the alternative source can be found in the menu Alternative source. Heating the storage buffer tank or DHW begins when the temperature of the alternative source reaches the set temperature difference (parameter Dif.Min.) between the alternative source and the buffer tank or DHW. Heating the buffer tank is performed until the set temperature in the menu Alternative source. The DHW has heating priority (parameter Prior. DHW.). When the temperature in the DHW is reached (parameter Set.Temp.) it is followed by the heating of the buffer tank. After the temperature of the buffer tank is reached the heating of the DHW is turned on again until the temperature set in the parameter Max.Temp in the menu Alternative source is reached. If the temperature of the alternative source is still higher than the temperature in the buffer tank, heating of the buffer tank continues until the parameter Max. Temp. (The maximum temperature of the buffer tank), set in the menu Alternative source. When the buffer tank and DHW reach the maximum temperature, heating with the alternative source stops. In case the temperature of the alternative source reaches the temperature of protection (parameter protection), a signal turns on which can control the users to lower the temperature of the alternative source.

NOTE

We recommend keeping the settings set by the authorised contractor for commissions.

5.7 Programme for drying screeds

The controller has a built in function of gradual drying of screeds which is especially important for new buildings and before installing flooring. Before using the programme for drying screeds you have to consult the contractor for screeds. According to his requirements you can use the standard programme or adjust it. The programme for drying screeds is located in the menu mode.

5.7.1 Standard programme

This programme consists of 8 steps and is normally adjusted for all systems of floor heating. Before activating this programme you have to set the maximum allowed temperature of the return water, i.e. 30 °C.

Steps 1-4: Heating Step 5: Maintaining the reached temperature Steps 6-8: Cooling

Steps 1 to 4 mean the heating phases which last 24 hours each (parameter Step). The needed maximum temperature of return water (parameter Maximum) is reached in four equal steps which start with 20,0 °C (parameter Initial). For finishing each step the time limit of 24 hours must be met. If the temperature of individual steps is reached sooner, the device maintains this temperature for the remaining time. In step 5 we maintain the maximum reached temperature at this level for additional 264 hours (parameter Duration). After this time the following step is possible. Steps 6 to 8 are cooling phases performed in equal steps as the heating, only in reverse order. Each step lasts 24 hours - which is a total of 72 hours, in this time the temperature of the return water falls from maximum temperature to 20,0 °C (parameter Final). When this programme finishes completely, the device returns to normal operation.

Example:

The maximum temperature of return water is 300 °C.

Steps 1 to 4: 20,0/23,3/26,6/30,0 °C – in 96 hours Step 5: 30,0 °C – constant temperature for 264 hours Steps 6 to 8: 26,6/23,3/20,0 °C – in 96 hours

In the user menu choose the menu Mode with the key and press the key

(ENTER).

Choose the Screed drying parameter by pressing and press the (ENTER)

key.

5.11 PV signal

The PV signal can be turned on in the menu mode with the parameter D8-PV. It allows factory and user settings:

► The factory control setting enables the control of the temperature operating mode. This

means that in the case of the winter mode (heating) you can turn on cooling. The parameter is set to D8-PV Cooling. It is most often used in combination with photovoltaic systems.

► The user control setting with parameters D8-PV Increase 1, 2, 3 ... enables the parameters

listed below to raise various operating modes and with it to change the temperature of the mode:

a) Increase 1: Comfort mode for the buffer tank. b) Increase 2: Comfort mode for the DHW. c) Increase 3: Comfort mode for the circuits. d) Increase 4: Comfort mode for the buffer tank and circuits. e) Increase 5: Comfort mode for the DHW and circuits. f) Increase 6: Comfort mode for the buffer tank and DHW. g) Increase 7: Comfort mode for the buffer tank, DHW and circuits.

5.12 Silent operation mode

Devices of the WPLV type enable two additional operation modes set in the menu Mode with the parameter Silent mode: The setting NRM switches the mode of operation into normal heating or cooling mode. The setting LOW lowers the parameters of power and noise of the device in the heating or cooling mode. The time and day of operation for these two parameters can be adjusted in a similar manner as the schedule. The lowered frequency of operation of the device means that the compressor and ventilators will operate with a lower power and consequently the operation of the device will be less noisy and its heating capacity will be correspondingly lower.

In the menu Mode use the key to choose the parameter Silent mode. When the symbols > < appear next to the parameter

Silent mode, press the key (ENTER).

The day blinks which the schedule refers to. Choose the day you would like to set the

schedule by using keys or . When you choose the day press the key (ENTER).
