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.
