Siemens QMX3.P34

The Siemens KNX Room Controller is an advanced device designed for precise climate control in modern buildings. Featuring a built-in temperature sensor, this controller ensures optimal comfort and energy efficiency. The backlit segment display and touch buttons provide a user-friendly interface for easy operation.

This versatile controller supports PWM and/or modulated signal (PID algorithm) for heating, cooling, or combined modes. Users can select operating modes via the KNX bus or directly on the display, including Comfort, Pre-Comfort, Energy Saving, and Protection modes. The device also allows for parameter selection for slow and fast radiator heating, as well as slow and fast underfloor heating.

Integrated with a bus coupler, the controller offers three independent settings for regulating CO2 concentration, relative humidity, and air quality. It features outputs for 1-, 2-, or 3-speed fans (humidity and CO2) and 1-, 2-, or 3-state outputs (humidity and CO2). Setpoint adjustments for room temperature, relative humidity, and CO2 concentration can be made via the KNX bus.

This controller is ideal for applications in residential, commercial, and industrial buildings where precise climate control and energy efficiency are paramount.
