2. FUNCTIONS

A. "TEMP" Button of the Panel

- Temperature control of Refrigerator compartment

- 5 step mode of successive temperature mode

- Initial mode by power input: step 3 (NOR)

- Temperature will be set if the button doesn't get pressed again within 5 sec.

- Whenever pressing "TEMP" button, setting is repeated in the order of
"NOR" → "MAX-NOR" → "MAX" → "MIN" → "MIN-NOR" (LED DISPLAY ON)

B. Temperature of Refrigerator Control

- COMP and FAN will be controlled by the on/off condition of each mode

- Temperature Difference of Refrigerator each step :

C. Temperature of Refrigerator at "NOR" OFF point:

-3.7℃
D. S-Cool (Quick REfrigeration) Mode

- Press "S-Cool" Button of the Panel and make "S-Cool" LED on.

- Comp & Fan are on until R-sensor reaches to "Over Refrigeration OFF Point", -9.5℃

- After the reach of -9.5℃, Step 5(MAX) mode continues.

- When "S-Cool" mode lasts for about 40 minutes, it returns to general operation mode.

E. Temperature of Freezer Control

-It will be only controlled by using “KNOB F LOUVER” in the Freezer Comaprtment.

- COMPRESSOR

- FAN
