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.
E
Adjust the heating system during the winter to obtain the greatest possible
output.
E
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 tempera-
ture, where the highest temperature is required, 20-21°C.
2
Place a thermometer in the room.
3
Open all the heating system's radiator valves fully.
4
Leave the heat pump's ROOM value set at 20°C. See section "7.2 Instructions –
Setting the ROOM value" for further 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 differ-
ent 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 section "7.3 Instructions –
Adjusting the CURVE value" for further 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 tempera-
ture the variation is greatest and adjust the curve at the corresponding value
(CURVE 5, CURVE 0, CURVE -5). See section "7.4 Instructions – Adjusting a spe-
cific part of the heat curve" for further information.
9
When the reference room has an even temperature of 20-21°C over a 24 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.
