Switching on and off

Once the mains fuse has been switched on, the LEDs of the selected operating mode and ventilation level light up on the wired room air controls → Operating keys, displays, LEDs.

PP 45 RC /PPB 30 RC radio-controlled ventilation units have 3 LEDs on the inner housing.

Select “ventilation level 0” to switch off the ventilation units.

To save energy, the LEDs are dimmed if not used for 5 minutes. Set value can be changed with commissioning software.
