7. OPERATION DESCRIPTION
7-1-1. Louver control
(1) Vertical air flow louver
Position of veritcal air flow louver is automatically
controlled according to the operation mode.
Besides, position of vertical air flow louver can be
arbitrarily set by pressing [FIX] button.
The louver position which is set by [FIX] button is
stored in the microcontroller, and the louver is
automatically set at the stored position for the next
operation.
(2) Swing
If [SWING] button is pressed when the indoor unit
is in operation, the vertical air flow louver starts
swinging. When [SWING] button is pressed again,
it stops swinging.
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.
7-1. 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 transmitted from
the remote control and the feedback data of the sensor
is as follow:
•The temperature measurement at the air inlet of
the indoor heat exchanger by the indoor
temperature sensor
•The temperature measurement at the indoor
heat exchanger by the indoor heat exchanger
temperature sensor
•Indoor fan motor operation control
•Louver motor control
•LED display control
•Outdoor fan motor operation control
•Compressor operation control
•Receiving the information of the operation
status and judging the information or the
indication of errors

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+, MED, MED+or
HIGH, the motor operates with a constant air flow.
NOTE :
*1: The values marked with *1 are calculated and
controlled by the difference in motor speed
between M+ and L-.

7-2-2. Cooling operation
([MODE] button on the remote control is set
to the cooling operation.)
(1) The compressor, 4-way valve, outdoor fan and
operation display on the remote control are
controlled as shown in Fig. 7-2-2.
Fig. 7-2-2
(2) When [FAN] button is set to AUTO, the indoor fan
motor operates as shown in Fig. 7-2-3.When
[FAN] button is set to LOW, LOW+, MED, MED+or
HIGH, the motor operates with a constant air flow.
NOTE :
*1: The values marked with *1 are calculated and
controlled by the difference in motor speed
between M+ and L-.

7-2-4. Heating operation *Heat pump model only
([MODE] button on the remote control is set
to the heating operation.)
(1) The compressor, 4-way valve, outdoor fan and
operation display on the remote control are
controlled as shown in Fig.7-2-6.
Fig. 7-2-6
(2) When [FAN] button is set to AUTO, the indoor fan
motor operates as shown in Fig. 7-2-7.When
[FAN] button is set to LOW, LOW+, MED, MED+or
