5.4.4 Setting the wall compensation
In case of unfavourable conditions at the installation site (installation
at the exterior wall, chimney, etc.), there may be deviations in temper-
ature between the temperature measured by the thermostat and the
actual room temperature. This difference in temperature can be com-
pensated with the wall compensation by setting an offset value.
Example: The difference between the measured and the controlled
temperature is 2°C, i.e. the room temperature is regulated 2°C too
high: Offset value -2°C.

5.4.5 Adjusting the controller behaviour
With suitable heating systems the PD controller is characterized by
a short setting time, scarce maximum overshooting and therefore a
high control accuracy.
With over or under engineered heating systems a hysteresis con-
troller is characterized by scarce shift frequency and small tempera-
ture deviations.
