The Sensor KNX AQS/TH-UP gl measures CO2 concentration, temperature and humidity and calculates the dew point. The sensor can receive external measured values via the bus and process them with the own data to overall values (mixed values, e. g. room average).

The KNX AQS/TH-UP gl provides switching outputs with adjustable threshold values. The switching outputs and further communication objects can be linked by AND and OR logic gates. Additionally, an integrated actuating variable comparator can compare and output values that are received via communication objects.

Integrated PI controllers allows for control of a ventilation (depending on CO2 concentration and air humidity) and a heating/cooling system (depending on temperature).

The KNX AQS/TH-UP gl can emit a warning to the bus as soon as the area of optimum comfort (according to DIN 1946) is left.
