7-1-2. Indoor fan control (AC Fan motor)
(1) The indoor fan is operated by the stepless speed
change AC motor.
(2) For air flow level, speed of the indoor fan motor is
controlled in five steps (LOW, LOW
+
, MED, MED
+
and HIGH). If AUTO mode is selected, the fan
motor speed is automatically controlled by the
difference between the preset temperature and
the room temperature.
This is a fixed capacity type air conditioner, which uses
AC motor for an indoor fan. The AC motor drive
circuit is mounted in the indoor unit. And electrical
parts which driving the compressor and the outdoor
fan motor, are mounted in the outdoor unit.
