Mains connection for heat pump controller PCB
In this case, the heat pump is operated using two electricity tariffs (two consumption meters).
A continuous power supply ensures the operation of the internal electric back-up heater and the control PCB of the heat
pump via its own electricity meter.
The power from the additional, blockable power supply for the compressor is supplied via a second electricity meter and can
be suspended by the power supply network operator at peak times. The duration and frequency of the outage is determined
by the power supply network operator or must be clarified with them.
