TIP: Voltage measurement:
The output voltage of the supply
air fans can be measured in the
set operating stage via GND
and S.
The controller has three, manually and freely definable operating stage, which can be
adjusted via the potentiometer on the circuit board via a potentiometer (with Phillips
screwdriver, Ø 3 mm; see Fig.1).
All three potentiometers S1, S2 and S3 are turned to the left stop as delivered. The
potentiometers must be adjusted to local requirements.
The airflow rate of the extract air fan can deviate in relation to the supply air fan in the
range of ±20 % via the potentiometer OS (offset for extract air fan).
