11. Defrost control
In heating operation, defrost operation is performed when TE sensor temperature satisfies any
condition in A zone to D zone.
The defrost operation is immediately finished if TE sensor temperature has become 12°C or more, or
it also is finished when condition of 7°C
≤
TE < 12°C has continued for 1 minute. The defrost operation
is also finished when defrost operation has continued for 10 minutes even if TE sensor temperature
has become 7°C or lower.
After defrost operation has finished, the compressor and the outdoor fan start heating operation after
stopped for approx. 50 seconds.
