Wall apparatus for controlling utilities

A method for installing an apparatus (1) for controlling utilities that can be installed at an internal cavity (2) of a wall in which the electrical connection cables to said utilities are present, wherein said method comprises the following steps:

• providing a wall support (6) having a through opening (7) for realizing a connection from and to said electrical cables;
• superposing said support (6) with an access mouth of said cavity (2) and fixing the support (6) to the cavity (2) through a fixing means (8);
• providing an electronic display device (5) for displaying graphical symbols and mounting it on the support (6) through a reversible connection means (9) in which said electronic device (5) extends completely outside the cavity (2);
• characterized in that the step of providing the support (6) envisages the fixing means (8) for fixing said support (6) being configured to fix said support (6) in at least two different fixing positions and displaced with respect to said cavity (2);
• said steps of superposing the support (6) with the cavity (2) envisage displacing the support (6) with respect to the cavity (2) so that the surface dimensions of said electronic device (5), after being mounted on said support (6), cover said mouth according to the shape and size of said cavity (2);
• said step of fixing the support (6) to the cavity (2) envisages using the fixing position corresponding to the superposing position of the support (6) on the cavity (2), said step of providing said electronic display device (5) comprising a sub-step of realizing a display screen (14) facing the outside and having a surface area such as to define an outer perimeter edge of the apparatus (1).
