The room controller directly affects the supply air tem-
perature controller.
Figure 26: PID controller
NOTE
The PID controllers are preset and need normally no adjustment. Changes (if required) may only be carried out by
qualied personnel.
Control output:
50 %: no heating or cooling demand
50 ... 100 %: heating demand 0 ... 100 %
50 ... 0 %: cooling demand 0 ... 100 %
- Heating: min. supply air temperature
min. supply air temperature Recommendation:
Keep the default settings. The factory settings ensure highest possible performance
and highest comfort.
Adjustment range: 8 °C ... 20 °C
Default setting: 16.5 °C
NOTE
If the min. supply air temperature is undershot during heat pump standstill in winter, the PTC elements will be activated
to min. power to avoid draughts (PTC function On). In this case, a setpoint decrease can be recommended.

- Heating: max. supply air temperature
max. supply air temperature This parameter enables limiting the maximum supply air temperature during heating
operation. It has signicant inuence on the unit performance coefcient. The lower
the temperature is set, the higher the efciency is. However, the efciency depends
on different factors (e.g. outdoor temperature, building standard) and can not be
generalized. The maximum supply air temperature is limited to 52 °C to avoid dust
carbonization.
