Supply/extraction airflow (dis)balancing
In the case that in the building is a chimney, gas oven or any apparatus which needs
combustion 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 airflow due to the natural draught of the
chimney.
This feature can be used also to balance once the installation is finished the two
airflows.
Example:
•
Minimum calculated airflow= 90m3/h
• Supply airflow necessary= 99 m3/h
→ Potentiometer position 5 = +10%

airflow.

The remote control allows:
- Adjust the airflows (1

speed)
- Timer for adjusting the filter maintenance period (6, 9, 12 or 15 months) (factory
setting 9 months)
- Adjust the balance of supply / extraction airflows
5.1 Adjustment of the airflows
To adjust the airflow turn the potentiometer carefully clock wise with a small screw driver.
The potentiometer has 16 positions (from 0 to F). To each of these positions are assigned
an output voltage to the fans. As higher the output voltage as higher the airflow and
viceversa.

Adjustment of the filter maintenance period
It is possible to set the period to 6, 9, 12 or 15 months (9 months factory setting). The
filter clogging depends on the pollution of the area where the unit is installed. We
recommend checking the time in which the filter clogs and adjusting this period. It is
advisable to do this after the second filter change. Of course, after the installation, the
extract air is dusty and not representative. During the second filter check, if you notice
that the filters are clean you can increase the time (12 or 15, months), if you notice that the
filters are very dirty you should decrease the time (6 months).
Open the box and adjust the timing as shown. To do this, set the micro contacts 1 and 2
as shown in the drawings below to adjust the month.
