These devices makes it possible to have a very simple setting from 4 up to 8 light preset scenes that can be altered anytime. Light scenes come up through different brightness of various electrical lighting fixtures. Depending on the use, the optimal light conditions for various needs can be memorized and recalled by the push of a button. The presets can be entirely set higher or lower through pushbuttons BRIGHTER and DARKER. The transition from one preset to another goes slowly sliding.

In multi-purpose rooms, restaurants, hotel lobbies etc., light as a formly element is simply to use. By push of a button the stored light presets can be retrieved and therefore can be exactly reproduced anytime. By using only part of the control buttons, one can create a control set with limited control possibility, for example, only the buttons for PRESETS and OFF, so it is not possible for unauthorized persons to change the stored values.

The installations are composed of one or various, parallel control tableaus, the control devices and any various dimmer devices which are combined according to the control devices. 10V dimmable electronic ballasts will be controlled directly by the control devices without dimmer devices.

Through Scene Switch Modules pure switching functions can also be integrated into individual light presets, e.g. a ventilator/fan is switched ON by preset 3.

Additional to the control tableau, an infrared or radio remote control with all functions of the tableau can be used.
