Müller KNX 24711 Room Temperature Controller with Air Quality, Temperature and Humidity Sensor GS 41.12 KNX RAL 9005

Maintaining a comfortable and healthy indoor climate in KNX building automation often requires multiple separate sensors and controllers, leading to complex wiring and configuration. The Müller KNX 24711 solves this by combining room temperature control with integrated air quality, temperature, and humidity sensing in a single flush-mounted device. It measures temperature, relative humidity, and volatile organic compounds (VOC) to provide a CO2 equivalent signal, enabling demand-based ventilation control. The controller supports heating, cooling, and ventilation functions with PI, 2-point, or PWM control, and offers Comfort, Standby, Night, and Frost Protection operating modes. A button allows manual presence/absence override. Configuration is done via ETS software. The housing is jet black (RAL 9005) plastic, designed for standard flush-mounted boxes.
