Operation:
Ac V • : if pressed, activates the 230V solenoid valve
Dc V1 • : activates the 24V solenoid valve for draining
Dc V2 • : activates the 24V steam dispensing solenoid valve
Dc V3 • : activates the 24V milk frothing solenoid valve
Dc V4 • : activates the 24V solenoid valve for milk circuit cleaning
Dc V5 • : activates the 24V hot water dispensing solenoid valve
Indicators
Tank • : indicates the status of the water tank level sensor. If activated,
the sensor signals that the level has been reached
Clean • : if activated, it indicates that the milk carafe is in the CLEAN position.
Milk • : if activated, it indicates that the milk carafe is in the MILK
dispensing position
Pres • : if activated, it indicates that the milk carafe is inserted
Operation:
Boil1 • : if pressed, this activates the coffee boiler. The boiler is deactivated
either by pressing the button again or automatically after 5 seconds. The
temperature is indicated in the corresponding window at the bottom
Boil2 • : if pressed, activates the steam/hot water boiler. The boiler is
deactivated either by pressing the button again or automatically after 5
seconds. The temperature is indicated in the corresponding window at
the bottom
Pmp1 • : activates the hot water dispensing pump. The pump is
switched off by pressing the button once more
Pmp2 • : activates the hot water/steam dispensing pump. The pump is
switched off by pressing the button once more
Indicators
p/s • : indicates moment by moment the water fl ow rate in the turbine, expressed in pulses per second. When
coffee pump 1 is switched on and the coffee solenoid valve is on (AcV on the previous screen) the value must be
no lower than 10 p/sec. When hot water/steam pump 2 is switched on and the drain solenoid valve is on (DcV5
on the previous screen) the value must be no lower than 5 p/sec.
50 Hz • : indicates the mains electricity voltage frequency.
DTray • : indicates the status of the tray level sensor. If activated, the sensor signals that the level has been reached

Operation:
Grind • : if pressed, activates the coffee grinder. To stop it, press the
button again. If the coffee grinder is not stopped, it will grind for 200
pulses; the corresponding countdown appears in the window.
BTEST • : if pressed, activates the coffee grinder. To stop it, press the
button again. If stopped, the no-coffee test is run. At the end of
the test, 2 values will appear in the "instantaneous threshold" and
"reference threshold" windows: if “instantaneous threshold” is less
than the “reference threshold” the system considers that the coffee
grinder is empty
