Motion sensor (PIR)

When operating with a motion sensor, the unit must be switched on. This activates the ventilation unit fans if there are people in the room. If the `Manual´ operating mode is selected, the unit runs in manual mode after movement is registered. If the `Auto/time´ operating mode is selected, the unit runs in sensor mode after movement is registered (demand-controlled). The overrun time can be adjusted (5...12...120 min).
