8 – BREWING UNIT CONTROL
8.1 – CCREMONA - CREMONA HC "V - V PID"
These models are equipped with automatic, continuous delivery
brewing units with solenoid valve and programmable coffee dosing,
microprocessor-aided sealed digital brewing control, control board
with 4 different coffee-dose selection positions, a stop button for each
brewing unit and a timer-aided hot-water delivery system.
9 – COFFEE DOSE PROGRAMMING DIRECTIONS FOR
THE CREMONA - CREMONA HC "V - V PID MODELS
17. UNIT CONTROL:
Key function:
A. 1 normal cup of coffee.
B. 2 normal cups of coffee.
C. 1 "large" cup of coffee.
D. 2 "large" cups of coffee.
E. Brewing unit stop/continuous delivery.
The "P" (E) button is designed for continuous delivery and delivery stop.
The machine therefore has a double function:
By pressing the "P" (E) button, the equipment is run as a semi-
automatic machine.
By pressing the 4 selection buttons, the machine is operated throu-
gh electronic dosing.
By holding the "P" (E) button pressed for over 10 seconds, the
machine will enter the programming phase, as signalled by the
low frequency flashing of the LED belonging to the unit on which
programming is being carried out.
Release the programming button (the LED will continue to flash) and
press the button relating to the unit on which you wish to program-
me coffee dosing; at this stage delivery will start; once the desired
dose has been reached, press any button of the unit concerned to
interrupt delivery; the dose will be stored in the memory and the
machine will exit the programming phase (the LED will stop flashing
and switch off).
1. This operation should be repeated on the remaining selection
buttons for the various groups.
2. The same operation needs to be repeated if you wish to incre-
ase or decrease the set dose.
3. By programming the first unit to the left, the programming ope-
ration will be also accomplished on the various groups.
N.B. The programming phase is signalled by the flashing LED of
the unit on which programming is being carried out.
10 – HOT WATER DOSE PROGRAMMING DIRECTIONS
By holding the "P" (E) button pressed for over 10 seconds, the
machine will enter the programming phase; release the program-
ming button (the LED will continue to flash) and press the hot-water
delivery switch (15); hot water delivery from the tap (13) will
start; once the desired dose has been reached, press the hot water
delivery switch to stop water supply. The LED will switch off, the
dose will be stored in the memory and the machine will exit the
programming stage.
11 – HOW TO SET THE UNIT BREWING COFFEE
TEMPERATURE BY MEANS OF THE PID (16)
The PID (16) has been set by the producer of this machine on a
temperature of 95°C. In order to change the temperature please
proceed as follows:
- press the button (F) ; as soon as the display shows the writing
"PRG" press the button (G) ;
- as soon as the display shows the brewing unit temperature, help
yourself with the buttons (F) and (G) in order to set the desired
temperature, starting from a min. of 80C° up to a max. of 133C°.-
after 3 sec. from pressing the last button, the inserted temperature
is memorized and the display shows the set temperature.
NB: if the temperature is set too high, once a coffee request is
made, the display starts to flash. The PID (16) is already set by the
producer on the right temperature for an excellent espresso.
During heating and coffee distribution, the temperature can oscil-
late (+/- 10/12°C).
Also, a warning has been inserted: after 108°C the PID's display
shows the temperature but intermittently; this is normal and it warns
the user that the coffee will not be good if made with such high
temperature.
12 – COFFEE DELIVERY
To obtain coffee delivery, press the selected button on the brewing
unit (17); the LED in the "P" (E) button will switch on, after which
coffee delivery will start and will be automatically interrupted once
the previously set amount has been reached. Delivery stop will be
signalled by the related LED switching off.
Delivery or selection deletion may be interrupted by pressing any
key on the brewing unit (17).
The "P" (E) button, besides interrupting supply or aborting selec-
tion, is also designed for continuous delivery, which means that the
dose is not previously set, but the unit will continue to deliver coffee
until the button is pressed again to interrupt delivery from that unit.
If the coffee is too finely ground or too much coffee is placed in
the filter, when you press one of the 4 control selectors (A, B, C,
D) coffee delivery will not start; after 45 seconds the machine will
be automatically blocked and the LED will switch from a fixed to a
flashing light state.
To restart the machine, remove the filter-holder and replace the cof-
fee contained in the filter, tpress the ON/OFF switch (1), in order
to turn off the machine and subsequently restart it.
N.B. We recommend a maximum delivery of 60 seconds.
N.B. To avoid the automatic block of the machine, if within 10
seconds coffee delivery has not yet started, press one of the selector
buttons to cancel the command, replace the coffee contained in the
filter and repeat the delivery operation.
