2-4 Outdoor Fan Speed Control
To optimize the performance of air conditioner, the outdoor fan speed is selected
automatically according to the outdoor temperature.
Note that in both Cooling and Heating modes, the fan comes on at first at high
speed (H mode) for 5 seconds. Since outdoor conditions sometimes make it
difficult for the fan to start, this sudden surge of power may be necessary.
The outdoor fan operates in H mode for 3 minutes after the compressor stops
(excluding defrosting operation period).
Charts below show how the outdoor fan speed changes with the change in
outdoor temperature.
