Detection area: rectangular. At a mounting height of 3 m: - Approaching the detector from the front, max. 20 m x 3 m (max. 10 m x 3 m per side). - Approaching the detector from the side, max. 30 m x 3 m (max. 15 m x 3 m per side). With integrated KNX bus coupler. Installation height 27 mm. With 4 channels. For dimming/regulating brightness to a defined value within a designated detection area. HVAC function for controlling heating and/or cooling systems as well as ventilation systems within the designated detection area. Detector application with 2-stage shutdown function. Detector application with integrated monitoring function. Constant light controller with up to 2 independent channels. Constant light controller with a maximum of 2 outputs for brightness-dependent dimming/regulating of two light bands in the room. Integrated object-room temperature controller. 10 freely programmable IR channels (blue and/or white) including 5 logic channels (logic gates, gate, delay, and stairwell light). Evaluation via internal brightness sensor. Weighting of up to 2 external brightness values and the internal brightness sensor is possible. The programming button can be activated with the IR remote control 6010-25. Ceiling mounting on suspended ceilings with spring clips, on solid ceilings in surface-mounted housing 6131/39, or on VDE flush-mounted boxes with spacer ring for VDE flush-mounted boxes 6131/38. Suitable for suspended ceilings with a panel thickness of 9 to 25 mm. Cut-out dimensions: Ø 68 mm. Not compatible with British Standard and VDE flush-mounted boxes.
