ARCUS 30301057


Product code: 30301057
The KNX-Sensor Temperature/Humidity/Climate SK01-TFK-KFF is used for temperature and humidity detection especially in airflows in ventilation and air conditioning ducts. The integrated KNX bus coupler does not need additional auxiliary supply. The temperature-humidity probe is enclosed in a sheath tube outside the casing.
Price (Excluding GST)


    The transducer with the bus coupler is enclosed in a durable, sealed, glass ball-reinforced plastic casing which fulfils protection degree IP65.

    Several controllers are available in the application software HVAC, Continuous, (PWM) for the temperature, and a two-position controller is available for humidity. Additional functions include frost alarm, temperature and humidity limits, minimum/maximum value and update. The climate controller displays absolute humidity (g/kg), dew point temperature (C), enthalpy (kJ/kg) and comfort according to DIN 1946.

    The sensor is configured with ETS (KNX Tool Software) and the application program. Controlling functions such as HVAC, switching threshold and various adjustment parameters are parameterised with ETS.

  • Areas of Application:

  • In air-conditioning ducts in heating technology
  • Decentralized heating regulation for constant KNX-Valves or electro-thermal valves
  • Decentralized ventilation controller
  • Dew point controller and alarm for cooling ceilings or winter gardens
  • Dew point alarm for identification of possible mould build-up in cellars
  • Shows saved maximum and minimum values on external displays
  • Room temperature controller with options Comfort/Standby/Night/Frost Protection
  • Direct set point presetting and display of current set point via KNX-Bus
  • Various disable options for the controller
