▪ For each room with heat pump convectors: 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
▪ For each room with underfloor heating: The desired room temperature is set via
the external room thermostat (wired or wireless).
▪ The user interface integrated in the indoor unit decides the space operation
mode. Mind that the operation mode on each external room thermostat and
controller of the heat pump convectors must be set to match the indoor unit.
INFORMATION
To increase comfort and performance, we recommend to install the valve kit option
EKVKHPC on each heat pump convector.
Configuration
Setting
Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]
Number of water temperature zones:
▪ #: [4.4]
▪ Code: [7-02]
If the heat emitters selected for each room are designed for different leaving water
temperatures, you can use different leaving water temperature zones (maximum
2).
In this document:
▪ Main zone = Zone with the lowest design temperature in heating, and the highest
design temperature in cooling
▪ Additional zone = Zone with the highest design temperature in heating, and the
lowest design temperature in cooling
CAUTION
If there is more than one leaving water zone, ALWAYS install a mixing valve station in
the main zone to decrease (in heating)/increase (in cooling) the leaving water
temperature when the additional zone has demand.
Typical example:
Room (zone)
Living room (main zone)
