Touch Pure CO2 Tree

The Loxone Touch Pure CO2 Tree features five touch points on a glass surface to control the most important functions of a room. When a button is touched, an audible click confirms the action.

The large center touch zone is ideal for controlling the lighting, while the corner zones are suitable for controlling music and shading. It is based on the Loxone switch standard. The buttons can also be freely used for other applications.

It also features a controllable orientation light and the integrated sensor measures temperature, relative humidity and CO2.

Please note that there is a certain delay when measuring humidity due to the housing. The Room Climate Sensor is better suited for a fast detection of changes in humidity.
