DISPLAY OF BOILER WATER TEMPERATURE AND PRESSURE ON DISPLAY 48
This display normally shows the temperature of the water in the boiler in °C. To check the corresponding pressure, just press
the button 43 beside the display (for not more than 5 seconds). The pressure value should correspond with the pressure shown
on the pressure gauge 44. If there are differences, contact the service center.
DISPLAY OF NUMBER OF COFFEES SERVED ON DISPLAY 48
This display also makes it possible to know the number of coffees served. The display shows the total number of impulses per
type of coffee (manual, single strong, normal, weak coffees; double strong, normal, weak coffees).
To access other data on the display, proceed as follows: press button 43 for about 8 seconds, until the value of the boiler
programmed temperature appears flashing, then release the button. Give one impulse again on button 43; the display will show
three dashes (---). If the buttons of the first unit are pressed, the total number of impulses through the push buttons of all the
units will be shown.
E.g.: If the "single strong coffee" button is pressed, the display will show the total number of coffees served by all the units.
If button 43 is pressed again, the display will show the code "CA"; this code indicates the access to count resetting. To delete
the counted values, press button 40. After this operation all the counting is reset and returns to the temperature value.
Emergency operation
(provided in case of failure of electronic control unit)
To set the emergency operation, press button "E" on panel 91.
This will light up the red led on the button itself.
Now, if button "1" is pressed, the first serving unit is activated.
If button "2" is pressed, the second serving unit is activated.
If the "THE" button is pressed, the hot water solenoid is activated.
The three buttons ("1", "2", "THE") work with the typical ON/OFF mode.
Pressing the button the first time activates serving; if it is pressed again, serving stops.
In this state, the pressure adjustment in the boiler is regulated by the mechanical pressure switch, while the level of the water in
the boiler is adjusted manually through the relative manually controlled valve 28.
When water is added to the boiler through this valve 28, always check the level on the visual level indicator 31, which must not
rise above 3/4 of maximum level and must not drop below the minimum level.
The display shows the time (hour-minute) and day of the week.
