When the guest presses the master on/off switch at the bedside, which enables the guest to turn on and off each of the lighting elements (armatures, spotlights, leds, bulbs, etc.) in the room from one or more (unlimited) points with the help of light switches, first of all (which is controlled by the system) ) that turns off all the lights that are on (Sleep mode), in the meantime, each lighting element can be turned on and off from its own switch without the need to press the master on/off switch again, and when the master on/off switch is pressed again, all the illuminations are turned on (Wake up mode). It is a system that increases the comfort of the room, where each lighting element can be turned on and off from its own switch without the need to press the master on/off switch again. The master on/off switch can be placed at more than one point (eg bedside and room entrance). The system remembers its last position during the mains-generator or generator-network trips; the same lighting situation is placed, the guest is not left in the dark. 16A relays are used, there are 4x16A and 8x16A panel unit models, more than one panel unit can be used together.
