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
