the amount relative to a selection is generally
cashed after the machine has sent the “successful
selection”signal.
If you enable this function, which is disabled by default,
the cash signal is sent at the start of the dispensing
cycle.

For every single selection key you can set the water
dose (expressed in cc - FB - In or “wheel strokes” es ac-
cording to models) for every single product composing
the selection.

mixErs
For every single selection key you can set the duration of
the mixing cycle for every single water dose composing
the selection.
The duration can be set in two different modes:
absolute
i.e. not depending upon the opening time of the solenoid
valve. the duration of the mixing cycle is set in tenths of
a second for instant models and in volumetric counter
pulses for espresso models.
relative
i.e. by way of difference, either in excess or in default,
compared to the closing time of the solenoid valve.
the duration of the mixing cycle is always expressed in
tenths of a second.

You can set (IN - FB - Milker - not used on this model)
the flow rate value of every single solenoid valve in cc/s
(the cc/s value set by default is supplied by the selection
dose table) to enable the user to calculate the cc that
shall be dispensed.

on instant models. Intermittence is programmable on a
percentage basis with reference to every single dispens-

be dispensed for prebrewing for every single espresso
coffee based selection (programmable from 0 to 20 cdv:
pulses of the volumetric counter, 20 by default).
p
rEssurizaTioN
this function is intended to set up for every single
espresso coffee based selection whether to provide
for pressurization or not, i.e. the hydraulic pressure of
the upper piston on the coffee dose during the brewing
cycle.
It is recommended to disable this function in case of fine
grinding on double espresso coffee selections.

pErcENTagE
this function is intended to modify the outlet water tem-
perature (maximum about 208°F) by acting on the flow
rate of the cold water that has been added.
Use the scrolling buttons to move the cursor on the dis-
play to a higher flow rate (colder water) or to a lower flow
rate (hotter water).
