The world-wide standard for home and building control Install intelligent room automation flexibly and future-proofed Multifunctional, based on KNX room operation devices for the individual requirements of all disciplines in rooms Intuitive operation for the entire room automation Room control units QMX3 with regulation features are available in six device versions, which are designed to work together, for controlling HVAC and electrical applications. They regulate the temperature, humidity and the carbon dioxide (CO2) concentration in the room in an energy-efficient way based on specific requirements. Customizable pairs of buttons cover electrical requirements with switching, dimming and scene features. Thus scenes, which simultaneously trigger several different actions in the room, can be programmed for various working situations and changed at any time, for scenes like Meeting, Presentation, Break or Unoccupied Room. Simple installation optimizes costs They cover an extremely wide range of room automation requirements. Bundling all functions in a single device serves to reduce to a minimum the effort required for installation and configuration. The room control units with regulation features can easily be integrated in a KNX system via the included bus connector. Wall mounting even allows for flexible positioning of the devices in the room. Attractive design with intelligent technology An LCD display and touch keys round off the design. Room users are informed of energy-efficient and comfortable air quality regulation via an LED indicator. U niform device range for multifunctional room requirements A ttractive design for wall mounting – not bound to frame lines F ast, highly precise measurement and regulation increase the level of comfort and energy efficiency in the room S implified and intuitive operation due to scene control via LCD display

Application examples Room temperature regulation with operation Key* 1 Room control unit QMX3.P34 Electromotive valve actuator AP 562/02 *Possible combination of components This application is recommended for smaller offices with a single heater. The room control unit measures and regulates room temperature and sends the regulation signal to the valve drive actuator via KNX bus. In addition to this, window contacts and presence detectors influence the regulation behavior of the room control unit and increase the room‘s energy efficiency. For example, if the room is unoccupied or if the window...
