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.

If this collector temperature is exceeded, the collector protection function starts. here targeted cycles are used to try to lower the temperature at the collector, provided the storage tank temperatures allow this. In this case the heating and heat pump controller may overheat the storage tank by 5 k to the set “T-diff. max”
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).

Charge mixer serves as charger mixer, possibly for a boiler
Discharge mixer serves as a control mixer, possibly for floor heating
Cool mixer serves as a control mixer for passive cooling function (on-ly for B/W devices)

This section is used to set a minimum op-erating duration for heating the swimming pool.
This may be necessary if a return flow is in-tegrated to prevent the system from con-tinuously switching between swimming pool and another supply type with a higher prior-ity.

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.

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:
