8.15.2 Integration of the heat pump in the heating system
Electrical connection of monovalent heat pump heating systems
Fig. 8.34: Connection diagram heat pump manager with monovalent systems with two heating circuits and domestic hot water preparation.
The four-core supply cable for the output section of the heat pump is fed from the heat pump meter via the utility company's contactor (if required) into the heat
pump (3L/PE~400V,50Hz). The system must be protected according to the power consumption data on the type plate using a 3-pole miniature circuit breaker with
C characteristic and common tripping for all 3 paths. Cable cross-section according to DIN VDE 0100.
The three-core supply cable for the heat pump manager (N1) is fed into the heat pump (device with integrated heat pump manager) or to the future mounting lo-
cation of the wall-mounted heat pump manager. The supply cable (L/N/PE~230 V, 50 Hz) for the heat pump manager must have a constant voltage. For this rea-
son, it should be tapped upstream from the utility blocking contactor or be connected to the household current, because otherwise important protection functions
could be lost during a utility block.
