MACHINE PARAMETERS
Water dose
The water dose (expressed in cc - FB - IN or “flow-meter
pulses” according to the models) can be set for each
selection button and therefore for each product assigned to
such selection.
Whipper Control
The whipping time can be set for each selection button, for
each water dose that composes such selection.
The duration can be set in two different modes:
Absolute
i.e. independent from the solenoid valve opening time. The
whipping duration is set as tenths of a second for Instant
models and as volumetric counter pulses for Espresso
models.
Relative
i.e. based on the difference, plus or minus, from the
moment the solenoid valve closes.
The whipping duration is always expressed in tenths of a
second.
Solenoid valve settings
It is possible to set (IN - FB) the water flow rate of the single
solenoid valves expressed in cc/s (the default value setting
in cc/s is indicated in the selection dose table) to calculate
the amount of water to be dispensed.
Powder dose
The powder dose expressed in grams can be set for each
selection button, for each product that composes such
selection.
For correct conversion of product dose values, the flow rate
of the single doser units, expressed in gr/s, can be set to
calculate the amount of powder to be dispensed; the same
function can be set also for the grinder.
Selection status
Each single selection button can either be enabled or
disabled.
Button-Selection
Permitting the association of a selection number, indicated
in the the selection dose table, to a button in the direct
selection keypad.
Checking selection number

of the boiler, expressed in °C.
After selecting the boiler, press the confirm button “ ”, the
temperature value on the display will start blinking and can

Tank
The machine water supply can be from the mains or from
an internal tank.
With this function it is possible to define whether the
machine water supply is from the mains (tank = 0FF), from
the tank with water level sensor (tank = ON) from the tank
without water level sensor (equipped base cabinet). With
this last option, also the coffee grounds counter for the tray
is excluded.

the confirm button.
Buzzer

board, the machine emits a sound signal when the button
are pressed and at the end of the selection.
Setting the regeneration counter
It is possible to display the message
“Replace water filter” after a programmable number of
selections. If set in the programming menu, it is possible to
reset the message with the door closed through a pass-
word, after replacing the filter.
Automatic wash
Option of setting the time when automatically cleaning the
mixers and rotating the brewing units installed. When
setting the time to 24.00 the function is disabled (default).
