How Does KNX Work?

The KNX bus line is the main central nervous system for all automatons. It is a green cable which is installed in addition to the conventional mains supply during a new build or renovation project.

All of the various building technology elements are then connected to one another vis the main KNX bus line in accordance with the KNX standard for building automation.

The cable system is then managed by such things as sensors, detectors, parameters, etc. — which can then be conveniently controlled by end users with a laptop, smart phone or tablet device.

The KNX bus is routed in parallel to the electrical power supply to all devices and systems on the network linking:

• Sensors (e.g. push buttons, thermostats, anemometers, movement) gather information and send it on the bus as a data telegram.
• Actuators (dimming units, heating valves, displays) receive data telegrams which are then converted into actions; and
  Controllers and other logic functions (room temperature controllers, shutter controllers and other)
• System devices and components (e.g. line couplers, backbone couplers).
