KNX combined controllers and sensors from Siemens
The QMX3 range of mounted controllers offers a combined sensor and controller in an easily installed wall-mounted device. The devices include high-quality temperature, CO2 and humidity sensors, as well as integrated PID controllers to control these measured variables. Some units have an LCD display.
Versions with a CO2 sensor can display the actual air-quality status either via a colour-change LED or on the LCD, depending on project requirements. Lighting and blinds can be controlled from the same unit, so no additional devices are required for total room automation control.
The wall-mounted option means installation is not dependent on any given wall box. The units use the KNX open communication protocol.
