CONTENTS REMARKS
6. SUPER FRZ. (Quick Freezing)
1) Comp. and F-fan are ON (about 150 minutes) regardless of F-sensor.
2) F-fan runs at 14V for the first 90 min., then at 12V for the rest time.

Temperature Control of Refrigerator Compartment (RC)
INPUT Control Object
1. REF SET. button
2. R-sensor
1. COMP
2. R-FAN
CONTENTS REMARKS
1. Temperature modes change by pushing the button.
2. R-fan are controlled by ON / OFF point of each mode.
3. RC [ON / OFF] DIFF : 0.35C
( RC middle OFF point : 0.3C)
4. RC [Low -> (Low-Mid) -> Mid -> (Mid-High)] DIFF : 1 degree respectively
5. Prevention of weak/poor-refrigeration
1) When weak refrigeration is sensed, comp. is ON regardless of F-sensor.
2) When R-sensor reaches R-fan OFF point, comp. is controlled by F-sensor and
R-fan turns OFF.
3) Sensing point of weak refrigeration : R
-sensor OFF point of each mode + 7C
4) Termination point : Same as R-sensor OFF point of each mode
