KNX is the Worldwide Standard for Home and Building Control.
KNX is communication protocol for intelligent buildings.
KNX is an "open bus", it allows to link age an electric closet every kind of KNX components switchs, dimmers, relays, meteo station, clock program, ...
The demand for building management systems is continuously increasing. They need more convenience,People need more safety and higher energy savings.
Whether in a single-family house or in an office complex, the demand for comfort and versatility in the management of air-conditioning, lighting and access control systems is growing. At the same time, the efficient use of energy is becoming increasingly important. More convenience and safety coupled with lower energy consumption can however only be achieved by intelligent control and monitoring of all products involved. This however implies more wiring, running from the sensors and actuators to the control and monitoring centers. Such a mass of wiring in turn means higher design and installation effort, increased fire risk and soaring costs.
In order to transfer control data to all building management components, a system is required that does away with the problems of isolated devices by ensuring that all components communicate via one common language: in short, a system such as the manufacturer and application domains independent KNX Bus. This standard is based upon more than 20 years of experience in the market, amongst others with predecessor systems to KNX: EIB, EHS and BatiBUS. Via the KNX medium to which all bus devices are connected (twisted pair, radio frequency, power line or IP/Ethernet), they are able to exchange information. Bus devices can either be sensors or actuators needed for the control of building management equipment such as: lighting, blinds / shutters, security systems, energy management, heating, ventilation and air-conditioning systems, signaling and monitoring systems, interfaces to service and building control systems, remote control, metering, audio / video control, white goods, etc. All these functions can be controlled, monitored and signaled via a uniform system without the need for extra control centers.
KNX is approved as an International Standard (ISO/IEC 14543-3) as well as an European Standard (CENELEC EN 50090 and CEN EN 13321-1) and Chinese Standard (GB/Z 20965).
KNX is therefore future proof. KNX products made by different manufacturers can be combined
– the KNX trademark logo guarantees their interworking and interoperability. KNX is therefore the world´s only open Standard for the control in both commercial and residential buildings.
According to VITY’s Products
VIMATY touch panel range can directly drive through one twisted pair all KNX components without additional interface. For home application, all the infrared audiovisual devices can be directly driven by VIMATY touch panel or through MBC controller if RS232, VCA or contact closure is needed.
With CUSTO LAN EIB MBC gateway controller, it is possible to control KNX components through IP or Web with TACTUM touch panel series or by a standard computer.
Do not required controllers and relays usually used between touch panels and electric power components anymore. Save up wiring, space and increase reliability. VIMATY touch panels are technically very interesting, they have a direct connection for KNX 2 wires bus to control any EIB modules of the market (HAGER, SIEMENS, MARTEN, ABB, JUNG, THEBEN, GIRA, BERKER, SIEDLE, ...).
