Heating control mode
• In
Outside temperature compensation control mode
only summer
mode, setback mode (depending on the selected type of setback)
and adjustment of the outside temperature (by reduced heating
requirements due to good insulation) can result in shutdown of the
heating circuit pump.
– Room adjustment can be set in the
Adjusting the heating curve
menu. Room adjustment influences the two outside temperature
controlled operating modes. Room influence is only available if a
room controller is installed in a suitable reference room.

Outside temperature compensated (optimised heating curve)
The heating curve provides an economic and convenient operation of
the heating system with outside temperature compensated control. The
operating system will based on the settings automatically calculate the
best possible heating curve. This results in a curve that is slightly bent to

The system temperature only applies during outside temperature compensated control without base
point. The system temperature is the flow temperature that is reached at the lowest outside temperature
and will therefore influence the slope of the heating curve.
The end point only applies during outside temperature compensated control with base point. The end
point is the flow temperature that is reached at the lowest outside temperature and will therefore
influence the slope of the heating curve. When the base point has been set to a value above 30°C the base
point is the minimum value.

Room temperature deviation equivalent to the setting is adjusted by a parallel offset of the heating curve
(only if a room controller is installed in a suitable reference room). The higher the setting value, the greater
