In this case, the heat pump is operated using two electricity tariffs (two consumption meters).
A continuous power supply ensures the operation of the compressor and the controller PCB of the heat pump via its own
electricity meter.
The power from the additional, blockable power supply for the internal auxiliary electric heating is supplied via a second elec-
tricity 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.
