1-5. Temperature Diagram
; The actual inner temperature varies depending on the food status, as the indicated setting temperature is a
target temperature, not actual temperature within refrigerator.
; Refrigeration function is weak in the initial time.
Please adjust temperature as above after using refrigerator for minimum 1 ~ 2 days.
* Features are model dependent
( Below is RN-271 model )
Refrigerator Dial Mode
MIN: 5 ~ 8℃
MID: 2 ~ 5℃
MAX: -1 ~ 2℃
Vegetable compartment
: 1 ~ 5℃
Freezer Mode
LOW: -17 ~ -19℃
MID: -19 ~ -22℃
HIGH: -22 ~ -25℃

- Features are model dependent ( Below is RN-271 model )
<'COVER M/FLOW DUCT AS': Air Duct Device in the Refrigerating Compartment>
- Temperature is controlled by "PCB Volume" assembled with "Dial Knob".
- 12step(0step ~ 11step) mode of successive temperature mode
- Each model is diffrent using range.
RN_271 Model: step 0 ~ step 10
RN_331 Model: step 1 ~ step 11

A. COMP and FAN will be controlled by the on/off condition of each mode.
B. Temperature Difference of Refrigerator each step :
C. Temperature of Refrigerator at Mid-'Dial Knob' OFF point :
- RN_271 Model : -3.16℃,
- RN_331 Model: -3.83℃
D. Refrigerator ON/OFF Temp.
Difference: 8.0C
E. Temperature of Freezer Control
-It will be only controlled by using “KNOB F LOUVER” in the Freezer Comaprtment.
- Turn 'DIAL KNOB'
- R sensor
