▪ For more information about connecting the electrical wiring to the unit, see
"8.2 Overview of electrical connections for external and internal
actuators"[480].
▪ For each room with heat pump convectors: The heat pump convectors are
directly connected to the indoor unit.
▪ 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 remote controller of the heat pump convectors.
▪ 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
remote 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.
