  • Individual scenes
    Presettings and the triggering of actions can be combined in individual scenes so that they can be called up at the touch of a button. For example, a living room can be prepared for a cosy evening of television within seconds - with the right lighting mood, lowered blinds, the ideal room temperature or even the right music.
  • Air conditioning & heating
    Thanks to the Smart Home System, the optimal room temperature can be controlled individually and according to actual needs. In this way, the temperature control can be adapted to the personal daily routine so that, for example, the bathroom is already preheated in the morning after getting up or not all rooms are heated during the day when you are absent.
  • Blind control
    With the blind control, blinds, shutters and awnings can be raised and lowered and the position for appropriate shading of the rooms can be set.
  • Lighting control
    With the lighting control, illuminants can be switched, controlled and dimmed. In addition, the color and color temperature of the lighting can be adjusted.

What distinguishes Busch-RoomTouch®?



The control element with display only requires a standard switch box for installation. Thanks to its extremely flat design (11 mm), the control element fits perfectly into modern interior design.
