„P14 : Supply air flow rate offset „
Use this parameter to adjust the supply air flow rate during com-
missioning. The offset relates to standard ventilation. The offset
is converted internally as a percentage for the other fan stages.
Example
- Nominal flow rate (stage 2) : 125 m³/h
- Offset : 25 m³/h
