Product code: 30302201
The KNX-sensor Temperature-Humidity-Climate SK02-TFK is used to measure the air temperature and humidity in dry interior spaces.
- 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.
