![CDATA[The square presence detector (PIR) for ceiling mounting indoors covers an area of 360° with a range of 9x9 m (81 m²) at a mounting height of 3 m. It is designed for the KNX bus system and has three light channels and two presence channels for controlling heating, air conditioning and ventilation systems (HVAC). The adaptive light measurement supports various lamp types, including LEDs, fluorescent and incandescent lamps. Operation can be switched to fully or semi-automatic, and dimmable lighting is available with a stand-by function. The brightness switching value is adjustable, and the run-on times and detection sensitivities can be adjusted. In addition, the detector enables scene functionality and offers an "eco plus" function for easy energy saving settings.]]>
