2. FUNCTIONS 2-4. Function of Low Ambient Temperature (RT) INPUT CONTROL OBJECT RT - R HTR - COMP A. Condition of LOW RT - RT sensor below 19℃ - When the RT sensor is over 20℃, the system comes to be “General Operation Mode”. - When the RT sensor is between 19°C to 20°C, the system keeps the previous mode. B. Control - When the temp of RT sensor is between 14°C to 19°C, COMP on/off temp is 3°C UP - When the temp of RT sensor is below 14°C, COMP ON/OFF temp is 4°C UP 2-5.
2. FUNCTIONS 2-7. Time Saving Function INPUT CONTROL OBJECT ”FAST KEY” Buzzer A. How to Save - 1 min : Click FAST KEY one time on MAIN PCB. - 30 min : If you press FAST KEY continuously, you can reduce 30 minutes on each 2.5 seconds with buzzer. B.
2.FUNCTIONS 2-8. Control of R-sensor OFF Point INPUT CONTROL OBJECT ”J1” , “J2” On Main PCB Control Resistance of R sensor OFF Point - When the refrigeration of refrigerator is poor or weak though Fan and COMP are working continuously, the following actions are recommended for service. (1) Resistance (R25) : Default resistance (31.4Kohms) (2) Resistance (R26) : Cut the “J1” off to reduce basic resistance by 1.5°C.
2. FUNCTIONS 2-9. Error Display INPUT CONTROL OBJECT Sensor Error LED Lamp - ERROR DISPLAY - If appliance has any errors, LED on the Main PCB is flickering. - If the appliance is normal (no error), LED IS off. A.
