Pressure control
The underpressure can automatically be adjusted to the current outside temperature to create a higher
underpressure when the outside temperature is low and a lower underpressure when the outside temperature is
high.
Example
Pressure setting:
20 Pascal
Compensation pressure:
-0.3Pa/°C
Starts outside temperature:
20°C
Current outside temperature:
10°C
Calculated pressure:
23 Pascal
Current outside temperature:
30°C
Calculated pressure:
17 Pascal
