QMX3.P74 Room Operator Unit KNX with Sensors for Temperature Humidity CO2 Segmented Backlit Display Touchkeys, White S55624-H106

The QMX3.P74 is a KNX room operator unit featuring a triple multisensor that measures temperature, relative humidity, and CO2 concentration, paired with a segmented backlit LCD in a white enclosure.

The CO2 sensor measures from 400 to 10,000 ppm, enabling automated demand-controlled ventilation through the KNX bus. PID temperature control with PWM and modulating outputs covers heating, cooling, and combined HVAC modes. Three independently adjustable CO2 and humidity thresholds drive fan stages and 1-3 point positioning signals for comprehensive indoor air quality automation. Operating modes can be adjusted via KNX or the panel touchkeys.

Educational Facilities: Schools deploy the QMX3.P74 to automatically boost ventilation when classroom CO2 exceeds thresholds, improving student alertness and concentration.

Healthcare Facilities: Hospitals and clinics use it to maintain sterile air quality in patient wards and treatment areas.

Corporate Offices: Businesses install it for energy-efficient demand-controlled ventilation in workspaces and meeting rooms.

Certification Support: The three-sensor data feed supports WELL building certification and ESG reporting targets for sustainable building management.
