Recess-mounted installation device compatible with the standard industry series, which perfectly fits in any environment thanks to 2 different finishes. All functions are available through the convenient touch-screen display, with an intuitive graphical interface that guarantees simple programming and excellent ergonomic use. It features two temperature-control modes: differential and integral proportional. This feature reduces the boiler switch-on times with respect to the difference between the room temperature and the set temperature. In this way it is possible to optimize consumption and keep comfort at optimum levels.
