The defrosting inhibit period is set as shown in the diagram below. When defrosting has
finished once, the inhibit period is newly set, based on the outdoor temperature when the
compressor was started. During this period, the defrost signal is not accepted.
(2) If the difference between the room and outdoor temperatures is large when defrosting is
finished, the maximum compressor speed (WMAX) or (WMAX2) can be continued for 120
minutes maximum.
(3) The defrosting period is 20 minutes maximum.
(4) When operation is stopped during defrosting, it is switched to auto refresh defrosting.
(5) Auto refresh defrosting cannot be engaged within 15 minutes after operation is started or
