2-1 Defrost operation
(AE-X08BE/X08BE-C/X10BE/X10BE-C/13BE)
(1) Overview
Defrosting begins during heating if the conditions for
compressor operation time and outdoor heat
exchanger temperature are met.
When defrosting begins, the indoor and outdoor fans
stop. Defrosting stops when the temperature of the
outdoor heat exchanger goes above approximately
5˚C or defrosting time exceeds 13 minutes.
2) Defrosting
If the compressor operation time is more than 20
minutes in the heating mode and the outdoor air
temperature and outdoor heat exchange temperature
satisfy the defrosting conditions, the defrosting
operation is started.
When the outdoor sheat-exchanger temperature
reaches approx. 5°C or above or when the defrosting
time exceeds 12 minutes, the defrosting operation is
quit.

(3) During defrosting
When defrosting begins, the compressor stops.
Approximately 1 minutes later, the compressor
reactivates in the refrigeration cycle, and the outdoor
heat exchanger is defrosted.
Each mode is as follows:
The outdoor fan is stopped
The operating frequency is as shown in the table
below The indoor fan is stopped
(4) Defrost stop
When defrosting time exceeds 13 minutes When the
temperature of the outdoor heat exchanger rises
above approximately 5˚C Defrost stop is determined
by either of the above conditions, and the compressor
is stopped. At the same time, the outdoor fan go ON.
The compressor is reactivated in the heating cycle 1
minute after it was stopped, and normal control
resumes.
2-2 Frequency control
(1) AC current peak control
(2) Control for prevention of indoor heat exchanger
overheating. If the temperature of the indoor heat
exchanger exceeds the overheating prevention line
1 or 2 during heating, the operating frequency is
lowered by approximately 5 to 10 Hz. After that, the
frequency is lowered by approximately 5Hz once
every 60 seconds or 10 Hz once every 120 seconds.
When the temperature of the indoor heat exchanger
goes below the overheating prevention line 1, the
frequency is raised by approximately 5 Hz once
every 60 seconds, and normal operation is restored.
If the frequency is lowered to minimum frequency
without the temperature of the outdoor heat exchanger
decreasing and this condition lasts for 1 minute, the
compressor will be stopped.
