The SK10-TTHC-KFF is an IP54/65 KNX duct sensor for temperature and humidity in ventilation ducts, with an extra input for an external PT1000 temperature probe (not included). It lets one device report duct air conditions and an additional temperature point, such as a nearby coil or pipe.

It measures temperature and relative humidity, calculates absolute humidity, dew point and enthalpy, and includes an integrated room temperature controller (RTR). The device is bus powered and configured in ETS with the HLK305 application.

Key Features

  • Duct temperature/humidity probe for ventilation ducts
  • 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
  • Input for a second, external PT1000 temperature probe (not included), -50 to +400 °C (-58 to 752 °F)
  • Integrated KNX bus coupler and room temperature controller (RTR)
  • IP54/65 plastic module housing, 72 x 64 x 40 mm (2.83 x 2.52 x 1.57 in)
