Display and knob (encoder)
The display of the electronic board can be viewed through the glass of the viewing
aperture on the front panel of the appliance.
Upon activation, all of the LED of the display light up for approximately three seconds, and
then the name of the board, S61, appears. Subsequently (if the on/off command switch is
in the closed position and the summer/winter selector is in the correct position for the
operating mode required), the appliance begins to operate.
During correct operation the display shows, alternately, the following information

temperature, inlet water temperature and the difference between the two water
temperatures.
