3.3 Electrical connection
Note: Earthing is required for protection against short-circuits inside the unit. Always
provide a good earth connection.
Before connecting the unit, verify that the supply voltage matches the required voltage of the
heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit breaker.
An auxiliary electric heater and water pump (max. 5 A / 240 V) can be connected to the
terminal block below. This allows the water pump or electric heater to be controlled by the
heat pump.
