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 temperature between
the temperature measured by the thermostat and the actual room temperature.
This difference in temperature can be compensated 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.
Offset value adjustable from –3 °C ... +3 °C. Setting with ▲or ▼. Confirm the
value with OK. Cancel with ESC.
5.4.5 Adjusting the controller behaviour
With suitable heating systems the PD controller is characterized by a short set-
ting time, scarce maximum overshooting and therefore a high control accuracy.
With over or under engineered heating systems a hysteresis controller is cha-
racterized by scarce shift frequency and small temperature deviations.
