Indoor unit

The task of the indoor unit is to distribute the heat from the heat pump to
the heating system and the hot water cylinder. The circulation pump in
the indoor unit module is RPM controlled, and will automatically
decrease in speed when demand is low. This decreases energy
consumption. When the heating demand is higher during cold outdoor
temperatures, an additional heat source - a booster - may be required.
This booster heater is integrated, it is controlled by the user interface in
the indoor unit. Please note that when the heat pump is running, the
booster heater will only provide the heating output that the heat pump

Hints on energy saving

• Use the normal heating mode, thus the heating system will use the
least energy. Set the desired room temperature according to your
personal comfort needs.
• Open the thermostatic vents fully in all rooms. Increase the
temperature setting on the control only when the desired room
temperature has not been reached for some time. Close the
thermostatic valve in a specific room, only if that room is warmer than
the others.
• If there is a room controller installed, this can be used to set the
optimal room temperature. Avoid influence of external heating (i.e
sunlight or wood stove). Otherwise unwanted fluctuations in the
room temperature may occur.
• Avoid placing big objects e.g. a sofa in front of the radiators
(minimum 50 cm distance). This will block the circulation of the
heated air in the room.
Vent the room correctly
Open the windows fully for a short period instead of leaving them ajar.
Leaving the windows ajar will let the heated air out of the room constantly
without increasing the air quality. Close the thermostatic valves or lower
the heating setting on the room controller while the room is vented.

cannot produce itself. When the heat pump is able to provide all the
heating needed, the booster is automatically turned off.
Pre plumbed cylinder
Heat pump AW OR connected to indoor unit Pre plumbed cylinder
provides a complete installation for both heating and domestic hot water
(DHW), since the indoor unit contains a domestic hot water cylinder.
Switching between heating and DHW is managed by an internal 3-way
valve. The integrated booster in the indoor unit will turn on if needed.
