▪ The outdoor unit is connected in series with the gas boiler.
▪ For each room with heat pump convectors: The heat pump convectors are
directly connected to the gas boiler.
▪ For each room with underfloor heating: A shut-off valve (field supply) is installed
before the underfloor heating. It prevents hot water supply when the room has
no heating demand.
▪ 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).
INFORMATION
To increase comfort and performance, we recommend to install the valve kit option
EKVKHPC on each heat pump convector.

▪ How many rooms are heated by the heat pump system?
▪ Which heat emitter types are used in each room and what is their design leaving
water temperature?
