LG SxS GR-B207 - Temperature Compensation Circuits

1-10. Temperature compensation and over-cool/weak-cool compensation circuit
1. Temperature compensation at freezing room, cold storage room
1) GR-P247, L247, P207, L207
2) GR-C247, B247, C207, B207
u Temperature compensation table by adjustment value (difference value against current temperature)
Ex) If changing compensation resistance at a cold storage room (RCR1) from 10 kΩ (current resistance) to 18 kΩ
(modified resistance), temperature at the cold storage will increase by +1°C.
