self-calibrating, in an elegant plastic housing, for determining the CO
ducer converts the measurand to a standard signal, which is directly presented visually by five coloured LEDs (traffic light indica-
tor). An additional signal tone sounds when the warning levels are reached (can be switched on via DIP switch). 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, and
improving well-being. The CO
