Energy Saving
20.1 Description
A series of technical innovations allows a substantial
reduction in energy consumption.
t
reduction of heat loss through insulation of the boil-
ers;
t distribution of power among the groups based on
operation via electronic control;
t
possibility to program reduced consumption or night-
time shutdown of the machine;
t self-learning of daytime working routine
t possibility to program the operating temperature of
the groups and boiler.
20.2 Energy savings programming
To achieve substantial energy savings, you can
activate the Energy Saving function when the machine
is not in use, for example at night.
In this phase the machine is not turned off, but is
placed at a lower temperature (programmable).
To program the machine's energy saving function,
refer to chapter "28 Programming".
20.3 Programming of group stand-by
The system lets you achieve further energy savings
setting two or more periods, during the days of operation,
when the functions of one or more delivery groups are
reduced (stand-by).
The configuration of these periods can be carried out
in two ways:
t manual programming: setting of stand-by start and
end time of the delivery groups involved only in 2
periods;
t
self-learning: the system, during the first week of
work, monitors the use of the machine and then au-
tomatically processes and sets the times and groups
involved in the stand-by (only if enabled as shown in
chapter 28 Programming);
to program the stand-by of the groups, please refer
to chapter "28 Programming".
