Surface-mounted device for switching and dimming 8 independent lighting groups. A maximum of 64 DALI participants can be connected to a DALI control output. In conjunction with 4 connectable light sensors LF/U 2.1, the device can be used as a light controller for constant light control. In this function, the device can be a key component in energy-efficient building automation. The device also has a staircase light and a master/slave function. Extensive fault messages, e.g. about electronic ballasts and lamp errors, are transmitted on the KNX.
Thanks to its surface-mounted housing, the DALI light controller can be used as a central device in the false ceiling or in the underfloor area.
