At basic setting the climate system "heating curve" and
"temperature" (heating curve offset) must be changed.
Further information on how to set the heating curve can
be found on page 49.
Setting automatic heating controls with diagram
The diagrams are based on the dimensioned outdoor
temperature in the area and the dimensioned supply
temperature of the climate system. When these two val-
ues "meet", the heating control's curve slope can be
read. This is set under "heating curve“ in menu 1.9.1.
