Two-stage small room fan with electric internal shutter and fully automatic humidity control, DN 100. This version features automatic humidity control and is barrier-free, with automatic switch-on and switch-off via a humidity sensor.

It can be operated without a switch and can also be operated via a separate switch as an option.

The switch-on delay can be set in stages using easily accessible buttons (only for control via switch): 0, 50, 90, or 120 seconds. The switch-off delay is adjustable in stages via easily accessible buttons: 8, 17, or 25 minutes. The run-on time is adjustable to 0 minutes only for control via a separate switch. The set time is indicated by LEDs during setting. It features a concealed intake with an electrically operated internal shutter and is not speed controllable.
