Pcb Control Functions
12 R-sensor - When refrigerator is over-cool or weak-cool, it is adjusted the
off point adjusting option option condition by R42 and R43(after deleting j7)
13 Functions of low 1) Low temp.: RT SENSOR ≤ 24ºC
temperature
2) Hysteresis DIFFERENCE: 1ºC
1- Mode of low temp. : RT SENSOR ≤ 24ºC
2- Mode of general temp.: RT SENSOR ≥ 25ºC
3- Mode of just before control : 24≤RT-S<25ºC
ex) 1- Mode of general control when is arriving to 24ºC
2- Mode of low control when is arriving to 25ºC
3) Control
1- When comp. is on, R-s HTR is off
2- The comp can't be on whiting 30 min after comp. off
3- At general temp. Mode of RT error, R-s HTR is off
4- At low temp. mode, R-s off point increase
2 degrees (ex) -0.5 to 1.5 C
4) R-s heater initial Operation
1- R-s heater turn on and off four times for 8 sec.
