10. Defrost control

<SP56 only>

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 continued 5°C £ TE < 12°C for

80 seconds. The defrost operation also finishes when it continued for 15 minutes even if TE sensor tem- perature was 5°C or lower.

3)After defrost operation was reset, the compressor stopped for approx. 40 seconds and then the heating operation starts.
