KNX bus system info


International Standard

As the international ISO/IEC 14543-3 standard, KNX is today’s worldwide leading open standard for home and building system technology. Solar protection, heating, alarm system, ventilation, lighting or support electronic devices are only examples for the multitude of areas in a building that can be monitored and controlled using KNX. Ideal energy management is possible by networking.

Because all sensors (e.g. brightness sensors) and actuators (e.g. lights, awnings) are networked via the databus, the system is very amenable to conversion and expansion. How sensors and actuators react with each other (e.g. what inside temperature and what brightness are relevant for an awning) is configured by software and can be changed at any time. Extensions and additions are possible without any problems.

The common standard generates new networking opportunities; all KNX-certified products are mutually compatible. Detailed information about KNX, both for investors and for planners and architects is for instance available on
