Pre-infusion and Sti
♦
STI
This function is common to all “coffee” cycles. It permits adjusting
when in the piston cycle the infusion starts, it is particularly
effective for the “1 cup” cycles. The “1 cup” quality is therefore
improved and more regular, therefore programming of all the
“coffee” key settings can be done by the PP mode.
Settings for 1 or 2 cups are done separately.
STI = 00 is the factory setting (ideal setting in 95% of cases)
(00 setting includes a small amount of pre-infusion)
STI = +01 to +100: infusion starts later (less pre-infusion)
STI = -01 to -100: infusion starts earlier (more pre-infusion)
STI = > 60 cancels the effect of the STI.
♦
Tamping level
There are four tamping levels.
A number gives the intensity of the tamping force; the higher the number, the more force is applied.
Level
Setting range
Default value
1
0,6 to 1,4
0,8
2
1,5 to 2,5
2,0
3
2,6 to 4,0
3,5
4
4,1 to 6,5
6,0
When exiting this setting, the machine automatically carries out self-check phases 1 and 2 to recalculate the
piston parameters generated by the new tamping values.
In general:
A small dose of ground coffee infused by a small quantity of water needs heavy tamping: Level 4
A large dose of ground coffee infused by a larger quantity of water needs light tamping: Level 1.
