For more information about connecting the electrical wiring to the unit, see:
-
"9.2 Connections to the outdoor
-
"9.3 Connections to the indoor
▪
For each room with heat pump convectors: The heat pump convectors are
connected as follows:
-
Warm water → Indoor unit
-
Cold water → Outdoor 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 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.
