INNOVATIVE FEATURES14
The innovative features
Energy Saving – (for VOPOS and SFU)
SMART DEFROST
Automatically detects the presence of frost on the evaporator and
initiates defrost only when necessary, maintaining, at the same time,
efficient operation of the refrigerator and reducing consumption
compared to traditional timed defrost.
For refrigerators at positive temperature, the SMART DEFROST lets
you switch from 3 days to 1 defrost in a defrosting every 3 days.
INTELLIGENT ENERGY SAVING
The ruleset is incremented by a default value (+1 / +2 ° max) when
passed an operating time with percentage of use compressor that
exceeds the threshold parameterized.
The restoration is set for early detection of a percentage lower than
the threshold allowed.15
The innovative features
Energy Saving – (for VOPOS and SFU)
NIGHT & DAY
During the night, if the nature of the stored product allows, you can
raise the temperature set a default value (+1 °C / +2 °C max).
During the activation of the night set , the lights are switched off in
vain.
THERMOSTATIC FAN CONDENSER (CAPACITOR)
The condenser fans are thermostat controlled with reference to the
probe installed at the exit of the condenser and the set point of
consensus.
Consumptions are minimized turning off the fan when the temperature
is below the set of consensus. In this way you can also optimize the
thermodynamic efficiency of the refrigerator in an environment of low
temperature.
ALERT “DOOR OPENED” DOOR OPENED
Scrolling message alerts you that the door is opened. If the opening
time is prolonged, it activates the buzzer.16

The innovative features
Static control of humidity (with a specific probe)
SMARTCLIMA
Inside the refrigerated compartment is implemented the humidity control in the neutral
zone with dehumidifying action of the static operating refrigerator.
This is an important feature for pralines without actuators.22
The innovative features
Automatic controller set-up of the probes (Self Configuration)
GENIUS
It is an automatic procedure to configure the operating parameters of the refrigerator,
with particular reference to the temperature sensors installed.
Allows you to avoid / correct the frequent errors of inversion probes being installed.
With this function, the controller will also be able to determine the defrost mode to
implement.

Testing of the refrigerator functioning through simulation
techniques (Hardware in the Loop)
Smartfreeze, in collaboration with university researchers, has developed a system that
allows you to emulate the operation of all components of a refrigerator, in order to test,
so fast (up to 15 times more), the behavior of the VOPOS controller.25 25
