Sensor for measuring the air quality, 230 V
Sensor for measuring the air quality for WS 170 L/..R.., WS 170 K.. and WR 600 ventilation units, rated voltage 12 V - 25 V AC or 12 V - 36 V DC
Sensor for measuring air quality and air humidity with a linear output signal of 0-10 V. For WS 170 KB.., WR 310/WR 410, WS 320 and WS 470 ventilation units. Depending on VOC and humidity levels, a potential-free switching contact can also be used and its switching point set using a potentiometer. If a potentiometer is completely turned to the right, the respective measurement values are not analysed (VOC and/or humidity). Rated voltage 12 V – 25 V AC or 12 V – 35 V DC
External VOC sensor for decentralised and centralised Trio ventilation units
Internal VOC sensor for decentralised and centralised Trio ventilation units
