c Heat pump convectors (+ controllers)
▪ For more information about connecting the electrical wiring to the unit, see
"9.2 Connections to the outdoor unit" [
4
91].
▪ For each room with heat pump convectors: The heat pump convectors are
directly connected to the outdoor unit – or to the external backup heater kit, if
there is one.
▪ For each room with underfloor heating: Two shut-off valves (field supply) are
installed before the underfloor heating:
- A shut-off valve to prevent hot water supply when the room has no heating
demand
- A shut-off valve to prevent condensation on the floor during cooling operation
of the rooms with heat pump convectors.
▪ 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 connected to the outdoor 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 outdoor unit.
INFORMATION
To increase comfort and performance, we recommend to install the valve kit option
EKVKHPC on each heat pump convector.

Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]

6.2.3 Multiple rooms – Two LWT zones
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
