An aesthetic part and an electronic section? What does it mean?

Vitrum consists of two elements: a glass masking plate (an eye-catching designer item that can be customized) and an electronic sub-assembly (Vitrum’s hi-tech wireless heart).

First the electronic section is secured to the wall, then the glass décor plate is snap-fitted onto the electronic section.

Thanks to this two-section structure, the user can change the appearance of Vitrum at any time after installing the system. The appearance of the control units can thus be modified simply  by purchasing new finishing panels to suit the new home décor
