Supply/extraction airfl ow adjustment
Settings
Date and hour
In the case that in the building is a chimney,
gas oven or any apparatus which needs com-
bustion air and there is no additional supply
air opening for this, it is necessary to adjust
the unit in the way that the combustion is not
affected. It is necessary to add a
supplementary air supply equal to the extract
airfl ow due to the natural draught of the
chimney.
This feature can be used also to balance
once the installation is fi nished the two air-
fl ows.
Example:
• Minimum calculated airfl ow = 90 m
• Supply airfl ow necessary = 99 m
g Potentiometer position 5 = +10%
The adjustment is made on the
supply airfl ow compared with
extraction airfl ow.
Adjust date and hour (automatic time chan-
ge between summer and winter time can be
activated.
