The SK07-THC-4B is a flush-box KNX controller module that installs behind the switch design of your choice and reads an external HTU21 temperature/humidity element, sold separately. It includes an integrated bus coupler and room temperature controller (RTR).

With the HTU21 element connected, it measures temperature and relative humidity and calculates absolute humidity, dew point and enthalpy. Four binary inputs/outputs are provided. The module is bus powered and configured in ETS with the HLK305 application.

Key Features

  • Connection for external HTU21 temperature/humidity element (not included)
  • Temperature -25 to +80 °C (-13 to 176 °F), ±0.4 °C (±0.72 °F) between 5 and 60 °C (41 to 140 °F); 0.02 °C (0.04 °F) resolution
  • Humidity 0-100 % RH, ±3 % RH between 20 and 80 % RH
  • Calculates absolute humidity, dew point and enthalpy
  • 4 binary inputs/outputs
  • Behind-the-switch module, 50 x 50 x 20 mm (1.97 x 1.97 x 0.79 in), for standard flush-mounted boxes; IP20
  • Bus powered; ETS application HLK305
