Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as
the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an
NRTL-listed power supply, many AHJs accept non-listed SELV devices.
Verify with your local AHJ before specifying.

The SK20-THC-VOC-2B is a KNX room sensor that measures temperature, humidity and VOC air quality and includes an integrated room temperature controller (RTR). The VOC sensor tracks mixed-gas air quality, a good basis for air-quality based ventilation control. Absolute humidity, dew point and enthalpy are calculated on board.
The complete white plastic unit measures 71 x 71 x 25 mm (2.8 x 2.8 x 0.98 in) and flush-mounts on a standard in-wall box. Two binary inputs accept local contacts, and the sensor runs on KNX bus power with no auxiliary supply.
Key Features

- Relative humidity 10 to 95 %, accuracy ±3 % (20 to 80 %); calculates absolute humidity, dew point and enthalpy
- VOC mixed-gas air quality measurement
- 2 binary inputs
- White plastic housing 71 x 71 x 25 mm (2.8 x 2.8 x 0.98 in), flush mount on standard in-wall box, IP20
- Integrated bus coupler and RTR; bus powered, no auxiliary supply; ETS application HLK305
