The Intra-Sewi KNX TH-L-Pr sensor for the KNX building bus system detects brightness and the presence of people in rooms. Additionally, it measures the temperature and humidity of the air and calculates the dew point. Via the bus, the internal sensor can receive external values of temperature and humidity and further process them with its own data into a total value (mixed value, e.g. room average). Integrated PI-regulators control ventilation (humidification/dehumidification according to humidity) and heating/cooling (according to temperature).

The Intra-Sewi KNX TH-L-Pr sensor can send a warning to the bus as soon as the comfort field according to DIN 1946 is left. Action variable comparators can compare and output variables that have been received via communication objects.

All measured values can be used to control limit-dependent switching outputs. The states can be connected through logical AND gates and logical OR gates.
