Parallel displacement of heating curve

Readjustment of room temperature setting, especially in plants without room sensor.
Produces a parallel displacement of the heating curve in order to achieve a better
match of heat generation and heat consumption.
Setting range
-4.5...+4.5
By changing the value entered, all room temperature setpoints will be appropriately
raised or lowered. This allows the room temperature setpoints to be matched to the
effective room temperatures.
If a nominal room temperature setpoint of 20 °C adjusted on the controller always
produces a room temperature of 22 °C, displace the heating curve downward by 2 °C.
Each setpoint readjustment, be it via the setting value or the operational level, is a
parallel displacement of the heating curve.
