Can I set the VELUX skylight to close automatically after a predefined period?

Yes, the VELUX ACTIVE app can be used to define a period after which the skylight will automatically close (i.e. time-based bathroom ventilation). To define the period, press the control centre icon (3 dots) in the upper corner of the room screen and set a timer. At the timer timeout, the window will automatically close. Automated control will resume automatically at the beginning of the next ACTIVE scheduled automation.
