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
