In this instance the heat pump is operated on two tariffs
(two consumer meters). A permanent supply (2) for the
secondary consumers (auxiliary heating, circulation
pumps, controller, etc.) must be ensured via a meter.
The low tariff supply (1) for the compressor is effected
via a second meter and can be interrupted by the power
company at peak times.
