(0.5 seconds), until the switch is closed (i.e. door closed).
。
(8) Power failure with memory: this refrigerator is designed with power failure with memory.
Specific status prior to power failure will be kept when the refrigerator goes into power failure;
power failure with memory: defrosting status, refrigerating, variable temperature and freezing
temperature gear setting, quick-freeze, quick-cooling, intelligent. Power failure without memory:
compressor protection, quick-freeze time, quick-cooling time.
(9) Control of refrigerator lamp: when the refrigerator door opens, its lamp lights; when it is closed,
the lamp is off. The refrigerator lamp automatically lights off when the refrigerator door keeps
open for more than 7 minutes.
(10) Fan/Damper control: when refrigeration is activated in the freezer compartment, the freezer
fan and compressor work at the same time. When the refrigerator door opens, the freezer fan
and damper stop working immediately. The compressor is under normal control with
compartment temperature until the refrigerator door is closed or the fan and damper return to
normal control after 7 minutes.
(11) Initial power-on status: the temperature of refrigerator compartment is set to be 3
℃
, -18
℃
for
the freezer compartment and
“
BeverageCooling
”
for the my zone temperature compartment
when the refrigerator is initially powered on. The refrigerator will not start up if the refrigerator,
my zone temperature and freezer temperature are between the starting temperature and the
stopping temperature. It starts when the temperature returns to that at the starting point.
(12) Display control: The display lights off if the refrigerator door is closed and the button is not

press the "My zone" button 5 times, then press "Lock" button for 1 times. The display
board displays "T2", began forced defrost.
Defrosting exits when the defrosting sensor
temperature reaches 12
℃
. The power of defrosting is 180W (rated voltage 220V). The
deviation shall be within 10W.
