7.7.4 Extra heating capacity
If a situation arises where the domestic hot water heat pump is not able to provide enough hot
water, it is possible to activate an auxilary electrical heater. About twice as much water can now
be heated in the same period of time. You can set the temperature to which the electrical heater
is to heat the water.
The electrical heater can be activated manually on the control panel.
Only use the electrical heater if necessary. The electrical heater consumes more energy than the
compressor.
7.7.5 Photovoltaic function
The domestic hot water heat pump can be controlled by a signal from a solar photovoltaic (PV)
converter or an energy meter, either as simple start/stop via a potential free contact or by a
variable signal.
Using the variable signal option, a certain output (DC or mA) from the (PV) inverter or the
energy meter corresponds to a given amount of excess power for use in the domestic hot
water heat pump. This excess power can be used to activate either an electrical heater, the heat
pump or both.
