With KNX, a house provides a significant contribution to looking after itself: motion detectors activate lighting as necessary. Windows and doors left open by accident are signalled using magnetic contacts and can be closed automatically. In addition, when the windows are open, the heating system reduces output. Using the Berker KNX bus system, your house can learn to adapt to changed environmental conditions. Actuators are selected according to the resources they are to switch or control. This allows e.g. switchable lamps, socket outlets or fixed-location consumers to be operated with switch actuators. The Berker KNX System so contains a special actuator type for each application.
