Thanks to a temperature probe suitably positioned on the steam spout and connected to the STlVAP input,
the temperature of the liquid heated by the steam is measured.
So by pressing the AUTOSTEAM key in position K6GRx key the EVVAP is activated until the temperature set
in the Programming for Simulation is reached (see paragraph below).
The display shows
Steam
It can nonetheless be interrupted early by pressing the steam key again.
Steam can continue to be dispensed when the temperature programmed is reached, by keeping the steam
key pressed.
If the temperature is not reached within a time-out of 120 seconds, steam dispensing ends automatically.
The system permits the contemporary dispensing of coffee, tea and steam.
If two or more of these are dispensed concurrently, the display shows the related indications alternately.

When powered, the dosage function detects the status of the level probe situated in the boiler and, if neces-
sary (water shortage), it arranges for the filling phase to be performed by energising the filling solenoid valve
EVlIV and the PUMP until the boiler contains the right amount of water.
(programmable Time-out envisaged on the filling phase - see TECHNICAl lEVEl Programming)
When the system is started, the level check and adjustment is enabled after approximately 6
seconds.
Every time the level probe situated in the boiler fails to detect the presence of liquid for 3 seconds, the filling
phase is started by energising the filling solenoid valve EVlIV and the PUMP. When the probe detects the
presence of water for 3 consecutive seconds again, the filling phase stops by de-energising the filling sole-
noid valve EVlIV and the PUMP.

The filling phase does not affect the possibility of performing both coffee or tea selections and a new
programming of the same. Only the triggering of the Time-out combined with the filling phase inhibits
the functioning of the keyboard and actuators.
