The integrated KNX bus coupler does not need additional auxiliary supply. The temperature is measured by a pendulum room probe.

Application areas include building automation, air conditioning and ventilation systems, clean room systems, greenhouses and large rooms and halls with high ceilings. The transducer with the bus coupler is enclosed in a durable, sealed, glass ball-reinforced plastic casing which fulfils protection degree IP65.

Using an additional external PT1000 Probe, a second temperature reading can be taken and used directly with the dew point regulator. 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 parameterized with ETS.

Areas of Application:

  • Recording the temperature and relative humidity outdoors/damp room areas
  • Decentralised heating regulation for constant KNX-Valves or electro-thermal valves
  • Decentralised 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
