Selecting ventilation level

The ventilation level is selected

• automatically when operating with the Auto sensor or Auto time automatic programme or
• manually at a control unit in Manual operating mode, Eco mode supply air or Eco mode exhaust air.

If the ventilation unit is running in an automatic programme and the ventilation level is changed on a control unit, the unit switches back to the automatic programme once the timer Duration of ventilation level has elapsed. The Off ventilation level also has a time limit.

In a manual operating mode, the ventilation unit runs continuously in the selected ventilation level until it is changed manually.

If the set humidity value limit is reached, excess humidity protection automatically switches to intensive ventilation.
