9-2) Temperature Control Function

When the system power is initally engaged, the default set temperature are -4℉for the freezer and 38℉ for the set refrigerator, respectively. The numbers shown on the digital display panel stand for the actual compartments temperatures. When the compartment temperatures go down, so do the numbers on the display panel, and finally they reach the set temperatures. Once the system is stabilized, the display temperatures are the set temperature.

1) Freezer Temperature Control.

To select a set temperature, press the Freezer Temp. button. The display shows the set temperature from -14℉to 8 ℉ in sequence.

2) Refrigerator Temperature Control.

To select a set temperature, press the Fridge Temp. button. The display shown the set temperature from 34℉ to 46℉ in sequence.

note) Because of the temperature sensor sensivity, the refrigerator can be under and/or over cooled when the air flow is blocked by stored foods. (Temperature range of the sensor : 15℉∼80℉)

In the event of a power failure, if the freezer temperature is maintained lower than 41℉, the last selected set temperature and functions memorized in EEPROM will be restored when the power is on.
