Heating control system
The indoor temperature depends on several factors.
During the hot season, solar radiation and heat given
off by people and equipment are sufficient to keep the
house warm. When it gets colder outside, the heating
system must be started. The colder its gets, the hotter
the radiators must be.
This adjustment is made automatically, however the
basic settings must first be made on the boiler, see the
section Room temperature - Default setting.
The Curve coefficient is set using menu 2.1 and with
the Offset heating curve knob.
If you do not know the correct settings, use the basic
data from the map opposite.
If the required room temperature is not obtained, read-
justment may be necessary.
NOTE!
Wait one day between settings so that the tem-
peratures have time to stabilise.
Readjustment of basic settings.
