Indoor Fan Control; Outdoor Fan Control - Toshiba RAS-13UKV-E Service Manual

8-1-7. Indoor Fan Control (DC Fan Motor)
(1) The indoor fan is operated by the stepless speed
change DC motor.
(2) For air flow level, speed of the indoor fan motor
is controlled in five steps (LOW, LOW
MED + and HIGH). If AUTO mode is selected,
the fan motor speed is automatically controlled
by the difference between the preset tempera-
ture and the room temperature.
LOW + = LOW + MED
MED + = MED + HIGH
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.
