6.5.6 Heating curve
The heating curve generates the flow temperature setpoint, which is used to maintain a
certain flow temperature level depending on the prevailing weather conditions. The
heating curve can be adjusted in different ways, thus matching the heat output and the
room temperature to individual needs.

720 1020 1320 Heating curve slope
When the heating curve slope is raised, the flow temperature increases as the outside
temperature drops. Or, in other words, if the room temperature is not correct at low
outside temperatures but correct at higher outside temperatures, the heating curve
slope must be readjusted.
Increasing the slope: Raises the flow temperature, especially when the outside
temperature is low.
Decreasing the slope: Lowers the flow temperature, especially when the outside
temperature is low.
Note!
The set heating curve is based on a room temperature setpoint of 20 °C. If this
setpoint is changed, the heating curve adapts automatically to the new value.
