These controllers are available in six different versions, allowing you to select the one that best suits your specific functionality needs.
There are models with or without an LCD display, with or without buttons, a version that only contains sensors, and a fully integrated version.
The new controllers feature built-in PI control for temperature and hysteresis control for humidity or air quality. Some models include our "Green Leaf" LED, which illustrates how to use energy efficiently within the environment, raising user awareness of the environmental impact of their installation and providing important energy usage information to the building's maintenance personnel or owners.
All models in this new series are for surface mounting and are powered via the bus, without requiring any additional power supply.
The QMX3 provides an elegant and highly functional solution that complements Siemens' current portfolio.
