egant plastic housing, for determining the CO
urand to a standard signal, which is directly presented visually by five coloured LEDs (traffic light indicator). Available in device
versions CO2 AP for direct wall mounting, CO2 UP for mounting on in-wall flush boxes and CO2 AP-A as a floor-mounted device
with a metal support.
The room sensor is used in classrooms, training rooms and convention centres, offices, hotels, apartments, shops, etc. and is
used for easy and quick evaluation of the indoor climate. This enables energy-saving room ventilation on an as-needed basis,
thereby reducing operating costs and improving well-being. The CO
