Install the auxiliary relay(s) according to good en-gineering practice.

– In case of heat pump indoor units with built-in controller:if space is available, plug the auxiliary relay onto the top hat rail in the control box of the heat pump. otherwise install the relay in an external housing (to be provided on site).

– In the case of heat pump outdoor units with wall-mounted controller or for connection of a dual system via the hydraulic module:Install the relay in an external housing (to be provided on site).

CautIon For information on unit-specific connections,

please refer to the operating manual for your heat pump.

After the expansion board is installed on the circuit board and connected, close the housing of the heat-ing and heat pump regulator…

Switch on the control fuse of the “wall regulator” or connect unit to power supply for “built-in regula-tor”. The expansion board is activated automatically and associated functions are enabled.

CautIon Before making any settings in the software, always

check the hydraulic integration.

electricalintegrationofthephotovoltaicfunction

The inverter of the photovoltaic system, depending on the available photovoltaic yield, must be able to output a switching signal for external use via a multifunctional relay.

If a floating switch contact is available at the inverter, this can be used directly.

The switch signal must be applied to the expansion board at the SWT input. If the switch contact is closed, the photovoltaic function is active.

t-Diff. Max Maximum storage tank temperature difference

If this storage tank temperature is reached, the circulation pump stops. In the case of the collector protection function, this temperature is increased by 5 k. If the actual temperature in the storage tank exceeds 95 °c, the circulation pump is generally deactivated and – if possible – it is discharged via the collector (for example, while shaded during the evening hours or at night).

Position Position of the second heat gen. 3

Tank ZWE3 is integrated directly in-to or on the heating or hot water storage tank

Integrated ZWE3 is integrated in the heat generator (= heat pump or associ-ated hydraulic component).




SupplyingexternalpowerSourceS

you can supply energy from an external tank to the heating circuit and to the hot water charging circuit if the temperature is sufficient.




The screen switches to the “Service” menu. here, select the menu field “settings”…

Scroll to menu field “temperatures” and select…

The screen switches to the “temperatures” menu…

tee Heating temperature of external energy source Heating

If the temperature in the external energy source (tank) is higher by the set value than the current heating set temperature, the heat pump is switched off. The energy from the tank is mixed with mixing circuit 2 (Set-ting: “charge”) and 2hg 3 (Setting: “Boil-er”) into the heating system based on the set value.

tee DHW temperature of external energy source Domestic Hot Water

If the temperature in the external energy source (tank) is higher by the set value than the current hot water set temperature, the heat pump is switched off. The energy from the tank is mixed with mixing circuit 2 (Set-ting: “charge”) and 2hg 3 (Setting: “Boil-er”) into the hot water system based on the set value.



notICe The value set under “TEE dhW” should not be

below 5 k, in order to prevent delays in heating of the hot water.

Save settings or cancel. Return to menu “Settings”.


controlbypreSetfixedvalue

due to the expansion board the heating and heat pump controller is extended to include the control function according to preset fixed value.

With this control function, individual return setpoint temperatures (fixed value) can be set. This is done us-ing an external third party controller by means of 0-10 v signal at the “Analog In”-input.

notICe The “control according to preset fixed value”

only affects the heating circuit (unmixed).

In the menu “Settings”, activate and select the menu field “System settings”…

The screen switches to the “System settings” menu. here, scroll down and activate the menu item “set-ting hc”. Select “Analog In”…

confirm “Analog In” selection…

Scroll to bottom of menu. Save settings. Return to menu “Settings”.

An external 0-10 v signal can now be used to preset the following return setpoint temperature as fixed values:

10 Volts 50°C Fixed value 9 Volts 45°C Fixed value 8 Volts 40°C Fixed value 7 Volts 35°C Fixed value 6 Volts 30°C Fixed value 5 Volts 25°C Fixed value 4 Volts 20°C Fixed value
