1) In heating operation, defrost operation is performed when TE sensor satisfies any condition in A zone to D
zone.
2) During defrosting operation, it finishes if TE sensor continued 12°C or higher for 3 seconds or continued
7°C
≤
TE < 12°C for 1 minute. The defrost operation also finishes when it continued for 10 minutes even if
TE sensor temperature was 7°C or lower.
3) After defrost operation was reset, the compressor stopped for approx. 40 seconds and then the heating
operation starts.
