Individual heat pump - Heating only
In a heating system with a single heat pump that is only used for heating, terminals 17 and 18
with the "External control signal/remote switch" function are used for the connection of the heat
pump.
Single heat pump - heating system and domestic hot water
In a heating system with a single heat pump that is used for heating and domestic hot water,
terminals 9 and 12 with the "Room thermostat" function are used for the connection of the heat
pump.
The heat pump controls the domestic hot water tank: Loading times of the tank, control of the
3-way valve and the feed flow set points depend on the settings that the user entered on the
control panel of the heat pump.
Therefore, the 3-way valve and the temperature sensor for the domestic hot water tank
must be connected to the heat pump.
