The outdoor fan speed is changed in the range of the speed shown in the above table,
based on the frequency of the compressor.
(When the compressor frequency increases, the outdoor fan speed is also changed to
higher speed. If the compressor frequency decreases, the outdoor fan speed is changed
to the lower speed as well.)
After starting up the outdoor fan, it operates with the following speed for initial 20 seconds.
After operating the defrost control function on heating mode except economy operation,
its speed becomes 950rpm (AB*A18L) and 1050rpm (AB*A24L)
regardless of the compressor frequency.
However, it returns to the normal speed control when the defrosting operation does not function
for 240 minutes after releasing the defrost operation or when the outdoor temperature sensor
detection value becomes higher than 5°C.
