▪ For the additional zone:
- The heat pump convectors are connected as follows: Warm water → Indoor
unit; Cold water → Outdoor unit
- The desired room temperature is set via the controller of the heat pump
convectors. There are different controllers and setups possible for the heat
pump convectors. For more information, see:
The installation manual of the heat pump convectors
The installation manual of the heat pump convector options
The addendum book for optional equipment
- The heating or cooling demand signals of each heat pump convector are
connected in parallel to the digital input on the indoor unit (X2M/35a and
X2M/30). The indoor unit will only supply the desired additional leaving water
temperature when there is an actual demand.
▪ The user interface integrated in the indoor unit decides the space operation
mode. Mind that the operation mode on each controller of the heat pump
convectors must be set to match the indoor unit.
