• This parameter allows the operator to
program the time of pre-brewing of
water with the coffee. Each group can
have a different programming.
• Pre-brewing has only two values to be
adjusted for each group. The time (in
seconds) for which the brewing valve
is open during the pre-brewing cycle
and the time (in seconds) for which
the brewing valve is closed during the
pre-brewing cycle; during this time the
pump is active. Once the pre-brewing
cycle is over, the normal brewing cycle
will continue until the end.
