QMX3.P34 Room Operator Unit KNX with Temperature Sensor Segmented Backlit Display Touchkeys White S55624-H105

The QMX3.P34 is a bus-powered KNX room operator unit with an NTC temperature sensor and a segmented backlit LCD that delivers a clear numeric readout of measured and setpoint temperatures. Touchkeys provide local climate control while the integrated bus coupling unit connects natively to KNX PL-Link and S-Mode.

PWM and PID algorithms cover heating, cooling, and combined modes with adjustable radiated and floor heating parameters. Comfort, Pre-Comfort, Energy Saving, and Protection modes switch via KNX or local touchkeys. Three adjustable CO2 and humidity thresholds drive multi-stage fan and positioning outputs for demand-controlled air quality.

Conference rooms and training spaces choose the QMX3.P34 for its clear segmented display showing current and setpoint temperatures at a glance. Healthcare and laboratory zones rely on the numeric readout for rapid zone condition checks.

Schools deploy it for local teacher adjustment with facility manager override via KNX. CO2 and humidity threshold outputs drive damper actuators in high-occupancy areas, sustaining healthy air quality without a standalone IAQ controller.
