FIGHTER 1140
The heating control system on the FIGHTER 1140 is
controlled by the outside temperature. This means the
flow temperature is regulated in relation to the current
outdoor temperature.
The relationship between the outside temperature and
the flow temperature is set using the control system,
also see section “Heating control system - Basic set-
ting”.
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 on menu 2.1 “Curve coefficient”.
