SK07-TTHC-4B 
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 and air quality
Detecting of component temperature and temperature control to prevent condensation and structural damage
Evaluation of external switches and push buttons for switching functions

Functions:
