摘要： Terminal apparatus, e.g. a ceiling diffuser, of a ventilation duct via which terminal apparatus the incoming air is directed into a room space or corresponding, and in which ceiling diffuser the flow aperture leading into the room space is adjustable in height, and for which adjustment the terminal apparatus comprises an actuator (6), such as an electric motor. The invention is implemented in such a way that two alternative functions are integrated into the terminal device, in the first function of which the ceiling diffuser maintains a constant throw length, and in the second function a constant air volume, and in that these functions can be selected with a switch connected to the actuator.
