Overview
The WRF04I detects movement in rooms and switches a relay contact, so lights can be turned off or the temperature reduced when a room is empty. It suits homes, offices and corridors. It uses a passive infrared sensor with 80 detection zones, covering about 7 x 5 m at 2.8 m distance. The relay has an 8 second follow-up time. It can be fixed straight to the wall, on a flush EU box or in a surface mounting frame.
