Integration of the heat pump in the heating system 8.15.5
Electrical connection of mono energy heat pump heating systems
Fig. 8.43: Connection diagram of a WPM EconPlus heat pump manager with mono energy systems with one heating circuit and domestic hot water preparation
The contactor (K20) for the immersion heater (E10) of mono energy systems (HG2) should be dimensioned according to the heat output and must be supplied by
the customer. It is controlled (230V AC) by the heat pump manager via terminals X1/N and J13/NO 4.
The contactor (K21) for the flange heater (E9) in the domestic hot water cylinder should be dimensioned according to the heating output and must be supplied by
the customer. It is controlled (230 V AC) by the heat pump manager via the terminals X1/N and J16/NO 10.
