FIGHTER 640P is equipped with outdoor temperature con-
trolled automatic devices. This means the flow temperature
is regulated in relation to the current outdoor temperature.
The relationship between outdoor temperature and flow
temperature is set with the “Heating curve selection” and
“Heating curve offset” knobs.
The diagram is based on the dimensioned outdoor temper-
ature in the area and the dimensioned flow temperature of
the heating system. When these two values “meet”, the
heating control's curve coefficient can be read.
Set the “Heating curve offset” accordingly. A suitable value
for underfloor heating is -1 and for radiator systems -2.
To read the calculated flow temperature, go to channel
selection 10.
Also see the section “Room temperature”.
