7-1. Outline of Air Conditioner Control
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.
The air conditioner is controlled by the controller
mounted in the indoor unit. The controller operates all
components based on the commands trVansmitted from

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.

7-2. Description of Operation Circuit
(1) When turning on the breaker, the operation lamp
blinks. This means that the power supply is on.
(2) When pressing [ ] button on the remote control,
receiving beep sounds from the indoor unit, and
the next operation is performed together with
opening the vertical air flow louver.
(3) Once the operation mode is set, it is memorized in
the microcontroller so that the previous operation
can be effected thereafter simply by pressing
[ ] button.
7-2-1. Fan only operation
([MODE] button on the remote control is set
to the fan only operation.)
(1) When [FAN] button is set to AUTO, the indoor fan
motor operates as shown in Fig. 7-2-1. When
[FAN] button is set to LOW, LOW
