KNX bus system

More comfort, more safety, even more energy savings: The demand for building management systems is continually increasing.

Whether in a single family home or in an office complex: The demands for comfort and usage for the management of air conditioning, lighting and access control are growing. At the same time, an efficient contact with energy is becoming more and more important. A high degree of comfort and safety with low energy consumption, however, can only be achieved through the intelligent control and monitoring of all products used. This implies, however, more cabling as well to connect the sensors and regulators with the control and monitoring stations. This required cable leads to more planning and installation work, an increased fire risk and rapidly increasing costs.

The answer: KNX – the world’s only open standard for home and building system technology

In order to route the control information to all of the components of the building automation, you need a system that handles problems with isolated solutions: It must guarantee that all of the components communicate in the same language. In short, a system like the KNX bus is required, which works independent of the manufacturer and the application. This standard is based on more than 15 years of experience in this market, among other things, with the previous systems from KNX: EIB, EHS and BatiBUS. It is possible to exchange information through the KNX transfer medium that all devices are connected with (through drilled two-wire line, radio, 230V network or IP / ethernet). Bus devices can either be sensors or actuators that are needed to control the building automation, for example for: lighting, shading / curtain systems, security systems, energy management, heating, ventilation and air conditioning, alarm and surveillance systems, interfaces to maintenance and building surveillance, remote control, meter reading, audio and video controls, household appliances, etc. All of these functions can be controlled, monitored and secured through alarms through a uniform system without requiring additional control centers.

Everywhere where KNX is used, architects, planners, installation companies – and above all the building owners and users – have clear benefits.

• Low energy costs, which leads to considerable energy savings
  Lighting and heating are only turned on when you need them- this is controlled, for example, through a time profile or presence detector. This saves energy and money. Additionally, the lighting can be automatically controlled depending on the intensity of the daylight: This is how a determined minimum brightness is guaranteed at each work space and the energy consumption is reduced (only light sources that are really required stay in operation).

• Time savings
  All linked devices connected with a single bus save considerable planning and installation time. A single manufacturer and application independent engineering tool software (ETS) allows for the planning, installation and configuration of all KNX certified devices and systems. Since the tool is independent of the manufacturer, the system integrator can combine products from different manufacturers with different communication media (two-wire line, radio, 230V network or IP/Ethernet) into a single system.

• Flexibility and ability to adjust to future developments
  A KNX installation can easily be adjusted to new applications and can be updated without any problems. New components can simply be connected to the existing Bus installation.
