KNX – the Worldwide STANDARD for Home and Building Control
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 strongly advises against the use of such cable, that does not fulfill the requirements - because neither the correct transmission nor the installation length of the cable (maximum 1000 m within a TP segment) can be guaranteed.
* create only one application program, not two.
* create one top-level parameter switching between the two parameter sets
* make the user parameters dependent on this parameter, being visible only if the setting is 'user'
* same for the manufacturer parameters
If you don't want to expose the manufacturer parameters to normal users, make the top-level parameter inaccessible (HiAcces = LoAcces = none).
Yes. The system has proved itself over many years, all over the world. It has been in-stalled in more than 100,000 homes, offices and buildings. Operation of the simple system platform is fail-safe and is based on SELV (safety extra-low voltage). A central processing unit is not necessary. If one of the components is removed, the entire system remains fully functional. You can depend on KNX.
With KNX , you can truly feel safe. All kinds of surveillance sys-tems can be integrated into KNX: for example, a movement detector in the entry area, indoor movement detectors in corridors, window and door monitoring and smoke detectors throughout the whole house. When you are leaving the house and would like to know, for example, whether all the windows are closed and all the lights are off, a central display next to the front door will tell you everything at a glance. When you are away, the system will simulate your pres-ence by automatically controlling lights and blinds in accordance with your everyday routine.
KNX costs less than you might think. No more, for example, than a good kitchen. The costs depend on what components you install, similar to the standard and optional features on a car. Not every model has to be top of the line.
Particularly in the long term, KNX makes good financial sense. Though the initial investment in the planning and construction phase may be higher than for a conventional solution, the ongoing costs in the operating phase are far lower. In other words: KNX pays for itself.
Yes. Because you can install KNX step-by-step, in accordance with your personal priorities. For example, minimise costs with selected functions like lighting control, blinds control or security functions. Other applications and functions can then be easily and conveniently added later.
Even if you are not looking to implement an KNX solution right at the start, be sure to allow for a bus line in your plans. The cost is minimal, the benefit immense. Because that is the only way of ensuring cost-effective networking of your building at a later stage – without having to tear open walls to do it.
No. Its operational controls simply offer you far more possibilities than a conventional solution. Those controls can be customary switches or a remote control. But KNX can be operated just as easily via movement detectors, displays, a PC, telephone, mobile, and/or TV, and even automatically by means of a built-in contact switch, e.g., one that switches off all the lighting in the house when the door is closed.
There are many. KNX allows you to operate all kinds of functions using one single system, either individually or in tandem: for example, shutters & blinds, lighting, or heating. KNX makes living and working simpler. For instance, you can save your favourite settings and retrieve them again and again at the touch of a button. On those long winter evenings, for example: dimmed lights, closed blinds and just the right temperature. One touch of a button and KNX takes care of it all for you. Whether by push-button switches or remote control.
