4-1-4) Restoration of Previous Settings Upon Power Failure
1) If the panel display is reset upon instant power failure, it will trigger nonsense calls at the call center.
To prevent this, the following measure is implemented into the unit. Upon the power supply, it initializes
the unit or brings back its previous settings based on the Freezer temperature.
2) Upon the initial power on, it checks its Freezer temperature. When it is lower than +5 , it is to be
considered as an instant power failure and it brings back all its previous operation functions (Power
Freeze, Power Cool, Vacation, Freezer Settings, Fridge Settings, Ice Type, Child Lock, etc) related to
the panel display.
3) When it is higher than +5 , it is to be considered as a long-period power failure and it will initialize the
panel display (Freezer: -20 , Fridge: 3 , Cubed).
