In this instance the heat pump is operated on two tariffs
(two consumer meters). A permanent supply for the se-
condary consumers (circulation pumps, controller,
etc.) must be ensured via a meter. The low tariff sup-
ply for the compressor and the auxiliary heating is ef-
fected via a second meter and can be interrupted by the
power company at peak times.
