Nibe FIGHTER 1240 - Heating Curve Settings

Settings
FIGHTER 1240
8
The heating control system of the FIGHTER 1240 is
controlled by the outside temperature. This means the
supply temperature is regulated in relation to the cur-
rent outdoor temperature.
The relationship between the outside temperature and
the flow temperature is set using the control system,
also see section Settings — Basic setting.
The diagram is based on the dimensioned outdoor
temperature in the area and the dimensioned supply
temperature of the heating system. When these two
values meet, the heating control’s curve slope can be
read. This is set under menu 2.1, Curve coefficient.
