Trimming the heating system
To obtain a heating system balance and obtain an even and comfortable indoor temperature,
you must adjust your heating system according to the example below.
⚠
Adjust the heating system during the winter to obtain the greatest possible output.
Trimming must be carried out over a few days as the inertia in the heating system
⚠
causes the indoor temperature 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.
Open all the heating system's radiator valves fully.
Leave the heat pump's ROOM value set at 20°C. See the "Instructions – Setting the ROOM
value" section for further information.
Note the temperature in the reference room at different points in time over a 2 hour
period.
Adjust the ROOM value so that the reference room reaches your required indoor tem-
perature of 20-21°C. Remember that other rooms will have different temperatures during
trimming, but these are adjusted later.
If the ROOM value must be adjusted more than °C upwards or downwards the CURVE
value must be adjusted instead. See the "Instructions – Adjusting the CURVE value" sec-
tion for further information.

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 great-
est and adjust the curve at the corresponding value (CURVE , CURVE 0, CURVE -). See the
"Instructions – Adjusting a specific part of the heat curve" section for further information.
9
When the reference room has an even temperature of 20-21°C over a 2 hour period, you
can adjust the radiator valves in the other rooms so that their indoor temperatures are
the same temperature or lower than the reference room.
