QMX3.P44 Room Operator Unit KNX with Sensors for Temperature Humidity Segmented Backlit Display Touchkeys White S55624-H143

The QMX3.P44 is a KNX room operator unit featuring a dual NTC/humidity multisensor and segmented backlit LCD display in white. It simultaneously measures ambient temperature and relative humidity, transmitting both values to the KNX bus for precise indoor climate control. The integrated bus coupling unit simplifies installation.

PID temperature control supports PWM and modulating output for heating, cooling, or combined operation. Three independently adjustable switching thresholds manage fan stages and positioning signals based on configured humidity targets. Operating modes can be switched via KNX or the touchkey panel.
