VVM 240

VVM 240 is equipped with an outdoor temperature
controlled automatic heating system. This means the
flow temperature is regulated in relation to the current
outdoor temperature.
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.
