eTR is a series of switches and room controllers. The devices are installed instead of normal switches – on the wall or over a switch box. Thanks to communication via the international building bus standards KNX or Modbus and integrated room climate functions, the eTR series makes residential and commercial buildings smart. Intuitively understandable symbols and large touch surfaces make it easier for young and old to operate the building technology, e.g. setting the room temperature, lighting or sun protection. The use of real glass and details, such as the perfect finishing of the edges, emphasize the design claim.
