RATION:
The compressor serves to compress the gas in the
thermodynamic circuit in order to generate the nec-
essary cooling capacity to chill the appliance com-
partments.
The compressor is managed by the Main PCB with
the aid of a relay and a triac that trips, in parallel
with the relay, only at the time of compressor power-
on and power-off to protect the relay from electrical
arcing when the contact is opened and closed. The
compressor

ture. The refrigerator compartment temperature is
controlled by a mechanical damper located on the
multiflow unit. The damper enables cold air from the
evaporator coil to cool the refrigerator compartment.
Temperature adjustment is performed in accordance
with specific rules if the following conditions occur:
•
Temperature detected by PCB sensor (on the
board) is between two values parameterised in
the EEPROM memory;
•
The time that has elapsed from the last time the
door was opened is greater than the relative pa-
rameter stored in the EEPROM memory;
•
The compressor power-on time is lower than the
parameter stored in the EEPROM;
The freezer compartment temperature is adjusted
by the electronic PCB. To set a lower temperature
tur n the knob clockwise, turning the knob
counterclockwise gives a higher temperature. The
refrigerator compartment temperature depends on
the adjustment of the freezer compartment tempera-
