Trimming must be carried out over a few days as the inertia in the heating system causes the indoor tempera-
ture to change slowly.
1. Choose one of the house’s rooms as a reference room for the indoor temperature, where the highest temperature is required,
20-21°C.
2. Place a thermometer in the room.
3. Open all the heating system’s valves fully.
4. Leave the heat pump’s ROOM value set at 20°C. See Service instructions, Important parameters for more information.
5. Note the temperature in the reference room at different points in time over a 24 hour period.
6. Adjust the ROOM value so that the reference room reaches your required indoor temperature of 20-21°C. Remember that other
rooms will have different temperatures during trimming, but these are adjusted later.
7. If the ROOM value must be adjusted more than 3°C upwards or downwards the CURVE value must be adjusted instead. See Service
instructions, Important parameters for more information.
8. If the indoor temperature varies several degrees despite trimming, a specific part of the heat curve may need adjusting. Check at
what outdoor temperature the variation is greatest and adjust the curve at the corresponding value (CURVE 5, CURVE 0, CURVE -5).
See Service instructions, Important parameters for more information.
9. When the reference room has an even temperature of 20-21°C over a 24 hour period, you can adjust the heating system´s valves in
the other rooms so that their indoor temperatures are the same temperature or lower than the reference room.

Customer information
After installation and test operation, the customer must be informed about their new heat pump installation. In the User guide there is a
checklist regarding the information that the installer must give the customer.
The serial number must always be given for warranty matters. The serial number is on the type plate, which is
attached to the heat pump and control unit.
