Special Programs
When you first start the appliance
If the freezer and defrost sensors are warmer than –5ºC, then the automatic test starts. The below
listed components will be tested respectively with 5 second intervals.
• Radyal fan for 5 seconds
• Drain heater for 5 seconds
• Defrost heaters for 5 seconds
• Evaporator fan motor for 5 seconds
• Compressor for 5 seconds
After 5 seconds, the appliance will start to run.
Defrost algorithm
Defrosting activates after 55 hours of total running time of refrigerator or 18 hours of total compressor
running time. Up to below mentioned reasons running times might decrease to 12 hours for refrigerator
or 15 hours for compressor.
• Amount of ice formed,
• Number of times the door is opened and closed,
• Duration the door remained opened,
• Sudden usage change ,
• Sudden Cooler Compartment temperature increase,
• Sudden Freeze Compartment temperature increase,
Freezer Defrosting time
Under normal conditions, defrosting period ends when the defrost sensor measures 8ºC. But if the
defrosting period exceeds 37 minutes, then the defrosting mode completion temperature will be rised
to 15ºC.
Cooler Defrosting time
The cooler defrost and the freezer defrost are operated parallel except those below.
If the cooler defrost sensor does not feel 5°C three times during a particular period of time.
•Defrost will be activated after the refrigerator works max 9 hours. According to the conditions of
usage, the defrost might be activated (due to mentioned those below) after the compressor works
min 5 hours.
•Consisted ice amount,
•Door open-close,
•Sudden usage variance,
•Cooler sudden temperature rise,
Delay of the compressor run
Compressor will be started after 5 minutes of defrost mode.
Low Voltage Program
In case of supply voltage lower than 170 V for more than 5 seconds, the low voltage program will stop
the compressor, evaporator fan motor, condenser fan motor and also the super freezing super cooling
functions. If this situation happens during the defrost mode, then the appliance will stop during
defrosting.
When the supply voltage reaches a value greater than 180V, the appliance will start again from the
defrost mode.
If the appliance was not stopped during the defrost mode, then will be stopped for minutes more for
compressor secure start-up and will be started from the last setted program.
When the electricity is off
• All the parameters and functions will be kept in the memory (except the child lock function)
• When the electricity is on if the defrost sensor measures <5ºC then the compressor will be started
after 5 minutes.
• The appliance will be started with the last program setted.
