For more information about connecting the electrical wiring to the unit, see:
-
"9.2 Connections to the outdoor unit"
-
"9.3 Connections to the indoor 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 user interface integrated in the indoor unit decides the space operation
mode.
▪
The heating or cooling demand signals of each heat pump convector are
connected in parallel to the digital input on the indoor unit (X12M/15 and
X12M/22). The indoor unit will only supply leaving water temperature when
there is an actual demand.
INFORMATION
To increase comfort and performance, we recommend to install the valve kit option
EKVKHPC on each heat pump convector.
