8-1-8. Outdoor Fan Control (DC Fan Motor)
Although the outdoor fan motor drives the outdoor fan by non-step variable system of the revolution speed, the
revolution speed is restricted to three steps on the convenience of controlling. If a strong wind is lashing outside
of the room, the operation may be continued as the outdoor fan stops in order to protect the outdoor fan motor.
If a fan lock occurred due to entering of foreign matter, the air conditioner stops and an alarm is displayed.

8-2. Description of Operation Circuit
• Turning [ON] the breaker flashes the operation
lamp.
This is the display of power-ON (or notification of
power failure).
• When pushing [START/STOP] button of the
remote control, receive sound is issued from the
main unit, and the next operations are performed
together with opening the vertical air flow louvers.
8-2-1. Fan Only Operation
(The Remote Control MODE Button is
Set to the FAN ONLY Operation)
• Once the setting is made, the operation mode is
memorized in the microcomputer so that the
same operation can be effected thereafter simply
by pushing [START/STOP] button.
• When the FAN button is set to the AUTO position,
the indoor fan motor operates as shown in Fig. 8-
2-1. When the FAN SPEED button is set to
LOW, MED, or HIGH, the motor operates with a
constant air flow.
• ECONO. mode cannot be set.
