SK30-THC 
KNX-Sensor used for measuring and controlling indoor air parameters

Applications:
Detection and control of room temperature and humidity
Decentralized control for steady KNX-valves or thermal actuators
Decentralized ventilation control depending on humidity
Evaluation of external switches and push buttons for switching functions

Functions:
Air temperature ( sensor in the housing ) also weighted with external temperature
Humidity ( sensor in the housing )
Calculated values absolute humidity, dew point temperature and energy content ( enthalpy )
Control functions for heating and cooling applications ( can be combined )
Setpoint temperatures for Comfort, Standby, Economy and Protection, selectable via KNX HVAC objects
Setpoint change via objects
Storage of minimum- and maximum-temperature
Heat- and frost-alarm
Limits for temperature and humidity
Fan control by humidity limits and external inputs
Detecting of dew point temperature and alarm / regulation at risk of condensation
Adaptation for setpoint and maximum temperatures
Controller output 0…100% or programmable PWM for thermal actuators
Valve rinse function
Second temperature controller as auxiliary controller
Two binary inputs / outputs ( floating )
The current state of the temperature controller can be indicated by LED’s.
Four logic blocks for the logical link between internal and external signals.
