Energy Saving System - Astoria STORM BARISTA ATTITUDE SAEP 2GR Use And Maintenance Manual

Energy Saving System

2.9
The machine is equipped with software that man-
ages the automatic stand-by system during breaks, the
night Energy-saving feature and the smart temperature
adjustment.
This allows saving a considerable amount of energy
during night breaks, whilst maintaining the machine in
a condition that permits a quickly return to operation.
Moreover, the software only distributes the power
where and when needed, thus allowing energy to also
be saved during normal operation.
If provided for in the programming, the software
automatically puts into stand-by one or more groups
when the workload decreases, also preparing them for
full capacity when needed.
Three choices are provided:
• : manual standby activation
• : programmed operation
• : self-learning management
For Energy saving activation see par. 7.13 on page 16.
2.9.1 Coffee heating unit
Each dispensing group is fitted with a thermally-
insulated coffee heating unit (1) for dispensing hot water
for coffees.
Heat is provided by an
electric heating element
(2). The heating unit in-
cludes a temperature sen-
sor (3) and a safety ther-
mostat (4).
The temperature sensor
(3) regulates and stabilises
the water temperature in-
side the coffee heating
unit. The safety thermostat (4) intervenes in the event
of a heating system malfunction. If the temperature
reaches 150°C, the safety thermostat intervenes by dis-
abling the heating element and reporting the problem
on the display.

The totally insulated steel services heating unit (5)
is used to produce steam for hot water, milk frothing
produced by the cappuccino maker, and to heat/froth
beverages.
The heating unit's water is heated by an electric heat-
ing element (6).

2.9.3 Dispensing group
The dispensing group (A) is made up of a metallic
block which is hooked onto the coffee heating unit (B).
The functions of the group are summarised as follows:
• When the motor pump and solenoid valve (C) are
activated, which are located on the side of the group,
this allows cold water to enter the heating unit (D),
and consequently the hot water in the heating unit is
carried towards the group to be dispensed (E);
• The electric cartridge heating element (F) which is in-
stalled inside the group, is controlled by the electronic
control unit and heats the group at a programmed
temperature;
• The temperature sensor (G) detects the group's tem-
perature and sends it to the electronic control unit;
• The safety thermostat (H) cuts in to prevent any risks
if there is a failure in the electronic system.
