The outdoor fan is controlled by TL sensor, TO sensor and the operation frequency.
The outdoor fan is controlled by every 1 tap of DC fan control (14 taps).
Only for 60 seconds after the operation has started, the maximum fan tap corresponding to the
zone in the following table is fixed and then the fan is controlled by temperature of TL sensor.

TO trouble
When TE ≥ 24°C continues for 5 minutes, the
compressor stops.
It is the same status as the normal thermostat-
OFF without trouble display.
The compressor restarts after approx. 2 minutes
30 seconds and this intermittent operation is not
abnormal.
In case that the status in item
frequently, stain on filter of the suction part of the
indoor unit is considered.
Clean the filter and then restart the operation.
