Design and materials

Theben's KNX room controller: a 4-inch touch screen on the wall of a room. It has up to 6 pages with 8 functions on each: lights and dimmers, RGBW and tunable white, blinds, scenes, the thermostat, the air conditioning and audio. Up to 8 temperature controllers set the mode, the temperature and the fan stage. It measures the temperature, the humidity and the light of the room, and a proximity sensor wakes the screen when someone comes near. You can put your own background pictures on it from a micro SD card.

  • Brushed metal or silky matte

    Four brushed finishes: aluminium in grey or black, brass and stainless steel. Six silky-matte finishes: aluminium painted in several layers and sealed, for a soft feel.

  • Black glass on a metal body

    The glass covers the whole front. The finish you pick is the body around it, 11 mm deep on the wall.

  • The room on one screen

    Swipe between the pages: the lights, the LED strip, the curtains, the air conditioning and the scenes.

Where it goes

By the door of the room, at 1.4 m to the centre, in place of the switches and the thermostat; away from the supply grille and direct sun. Besides the KNX bus, it needs a 12 to 30 V DC supply.
