KNX interconnects all the components in the electrical installation to form a networked system and thus guarantees the transparency and utilization of information across the installation. In this system, all users “communicate” via a single bus cable. Thus it is possible to integrate all the different functional subsystems within the building into a seamless solution.

Complete product range

The ABB i-bus® KNX product range includes components covering the complete spectrum of applications found in today’s buildings, ranging from lighting and shutter control to heating, ventilation, security, energy management, and many more.



ABB i-bus® KNX ensures optimum lighting of industrial and office buildings as well as private dwellings. The lighting requirement is monitored and controlled. In addition, subsystems (such as for example 1 – 10 V lighting control, DALI) and their interfaces are supported.

Heating, ventilation and air-conditioning

heating_buildings_292x196ABB i-bus® KNX intelligent building control integrates the heating, air-conditioning and ventilation to a coherent and efficient climate control. Measured temperature values in the rooms are recorded and supplied to the heating and climate control to generate the optimum temperature and air quality.


shading_buildings_292x196Sensor controlled roller shutters, windows and blinds with sun position controlled louvres allow for optimal lighting conditions and contribute to an improved climate control in the room.

Security and safety

security_buildings_292x196The combination of ABB security technology components (e.g. smoke detectors, window contacts) and the ABB i-bus® KNX devices (Security Terminals and Security Module) provide optimum building monitoring and warning against unauthorized entry. Furthermore, emergency call stations allow immediate notification if help is required. Technical detection alarms (water, smoke, gas) can also be integrated.

Energy management

energymgmt_buildings_292x196ABB i-bus® KNX is designed to reduce building operating costs and to employ the required energy according to demand and as economically as possible. The diverse control and interface solutions of the ABB i-bus® KNX intelligent building control system are particularly suited to this task.

User operation

useroperation_buildings_292x196Clear representation of the control processes in a building is a prerequisite for comfortable and safe operation. States are visualized with the versatile control, signaling and operating devices. User entries are made using buttons, on the touch panel or on a computer.
