  • Page 6: Description

    Description Description The Sensor KNX AQS/TH-B-UP measures CO 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 vealues (mixed values, e. g. room average). The KNX AQS/TH-B-UP offers two push buttons that may be used for changing the ambient temperature (target value), for switching between operating modes or as free programmable bus push buttons.
