Adjustment - Orcon HRC-EcoMax Series Installation Manual

6. Adjustment

6.1 DIP switches
The DIP switches on the printed circuit board are used to adjust the air volume for
each ventilator. The upper row of DIP switches controls the extractor ventilator and
the lower row controls the supply ventilator. Because both ventilators can be set inde-
pendently, it is possible to create a difference in the amount of air. This can be used
when a negative or positive pressure is desired.
