Caution,
1.To protect each fan motor and compressor from abnormal current, over current relays<51C1,2>, <51F1~3>are
installed.
Therefore, do not change factory set value of over current relays.
2.Do not change factory set value of all timers.
3.This timer <TCZ> installed because the power supply breaker may operate if two compressors start at the same time.
