OPERATION AND FUNCTIONS
.
3- 3 Temperature Control of Refrigerator Compartment (RC)
1. fridge set button
2. super cool
1. Temperature modes change by pushing the button.
Low Low -Mid
2. R-fan are controlled by ON / OFF point of each mode.
3. RC [ON / OFF] DIFF : 0.5
( RC middle OFF point : 1.3
( If RT≤ 13
C , R-S OFF point increases by 2℃ and
4. 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 + 7
4) Termination point : Same as R-sensor OFF point of each mode
5. Control point of each mode
