7.4 Special functions
Pre-infusion
Our software permits measure
configuration so that the relative delivery
of the COFFEE measures through
volumetric control is preceded by pre-
infusion. Delivery of the coffee measure
after time 1 (ON) is suspended for a time
2 (OFF) and is then resumed for the
completion of selection.
On pressing one of the volumetric control
measure keys, the normal delivery cycle
is preceded by a short timed water jet in
order to dampen the coffee pellets before
actual delivery stage.
This function ensures the optimum use of
the coffee pellets.
