Room adjustment example at room 20 (with heat curve 40)
The ROOM value (marked as (20) below ) is used to lift or lower the heat curve (keeping the same inclination)
with 3 degrees / step. This means that the indoor temperature will change approx 1 degree per step up or
down on room value change. The Room value should be considered as a reference to make the basic heating
adjustment more intuitive, and may not always reflect actual indoor temperature.

General guideline for adjustment:
Provided that the heat curve is initially adjusted for the heating system, the following general & simplified rec-
ommendations can be used as guideline:
If the outdoor temperature is warmer than -5°C and the indoor temperature is not as desired, change the
ROOM setting one step up or down to change the indoor temperature ~1 degree up or down.
If the outdoor temperature is lower than -5 degrees and the indoor temperature is not as desired (but it was OK
at warmer out door temperatures), change the HEAT CURVE setting 1-2 degrees up or down to change the in-
door temperature approximately 1 degrees up or down.
If the temperature is as desired in general, but not 5/0/-5 degrees out door temperatures, the heat
curve can also be fine-tuned just around these temperatures. In many cases an increase of 1-2 degrees may be
suitable at these out door temperatures to compensate for effects by wind and unstable weather conditions.
By adjusting the heat curve & room setting correctly (as low as possible provided that the desired indoor tem-
perature still can be kept), the savings efficiency and life time of the heat pump is maximised.
