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 (15 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.


The outdoor fan is controlled by TE sensor, TO
sensor and the operation frequency. It is controlled
by every 1 tap of DC fan control (15 taps).
‚
Only for 60 seconds after start-up of operation, it is
fixed by the maximum fan tap corresponded to the
zone in the following table, and then the fan is
controlled by temperature of TE sensor.
ƒ
When temperature of TD sensor became high
sufficiently, it is controlled so that the fan revolution
frequency will become higher ignoring TE sensor
temperature.
