Product code: 30303201
The KNX-sensor Temperature-Humidity-Climate SK03-TFK is used to measure the air temperature and humidity in dry interior spaces and fits within 55x55mm frames such as Gira.
- The integrated KNX bus coupler does not need additional auxiliary supply. The transducer with the bus coupler is enclosed in a plastic casing which fulfils protection degree IP20.
- 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.
