program.
NOTE.- In each sub-screen corresponding to each of the eight possible programmes for
automatic start up and close down, the upper line shows the start up condition and the
lower line the close down condition.
6. Examples of programming:
a) Starting and stopping every day.
b) Starting on Monday and stopping on Tuesday.
c) Starting on Monday and stopping on Friday.
d) If the premises close for one or more days each week, the simplest way of programming
is to create an automatic on and off program for each day of activity during the week.
e)
To do this put the machine in Standby Mode (2.1) at the end of the day.
NOTE: The machine always obeys any on-off programme there is on the sub-screens (from F1 to
F8). To cancel any programming carried out, go through points 1 to 4 of this section,
selecting in the position corresponding to the day for starting and stopping the following
symbol: ------- (do not forget to confirm the change made as described in point 4 of this
section).
If the machine is on standby waiting for an automatic start, the power supply is cut and
returns after the programmed start time, the machine will remain on standby and will have
to be started according to point 2.1
Standby Mode (2.1)
In the case of making a coffee (in programmed portions) when there are less than 5
minutes remaining before an OFF programming, 5 minutes will be added from the minute
