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 adjus-
ted instead. See Adjusting CURVE values 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 Adjusting a specific part of the heat curve 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
radiator valves in the other rooms so that their indoor temperatures are the same temperature or lower
than the reference room.
