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 [FIX] button is pressed, 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.
Table 7-1-1
7-1. Outline of Air Conditioner Control
This is a fixed capacity type air conditioner, which uses
a AC motor for an indoor fan.The AC motor drive
circuit is mounted in the indoor unit. And electrical
parts which operate the compressor and the outdoor
fan motor, are mounted in the outdoor unit.
The air conditioner is mainly controlled by the indoor
unit controller.The controller operates the indoor fan
motor based upon commands transmitted by the
remote control and transfers the operation commands
to the outdoor unit controller.
The outdoor unit controller receives operation
commands from the indoor unit, and operates the
outdoor fan motor and the compressor.
(1) Role of indoor unit controller
The indoor unit controller receives the operation
commands from the remote control and executes
them.
•Temperature measurement at the air inlet of the
indoor heat exchanger by the indoor
temperature sensor
•Temperature setting of the indoor heat
exchanger by the heat exchanger sensor
•Louver motor control
•Indoor fan motor operation control
•LED display control
•Transferring of operation commands to the
outdoor unit
•Receiving of information of the operation status
and judging of the information or indication of
error

7-2. Description of Operation Circuit
(1) When turning on the breaker, the operation lamp
blinks.This means that the power is on (or the
power supply is cut off.)
(2) When pressing [START / STOP] 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
[START / STOP] 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.

(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.

7-2-4. Automatic operation
([MODE] button on the remote control is set
to the automatic operation.)
(1) One of 2 operations (Cooling, Fan only) is
selected according to difference between the
preset temperature and the room temperature at
which the automatic operation has started, as
shown in Fig.7-2-6.The Fan only operation
continues until the room temperature reaches a
level at which another mode is selected.
(2) Temporary Auto
When the TEMPORARY button on the indoor unit
is pushed, the preset temperature is fixed at 24°C
and the indoor unit is controlled as shown in
Fig. 7-2-6.

7-2-3. Dry operation
([MODE] button on the remote control is set
to the dry operation.)
(1) The compressor, outdoor fan and operation
display on the remote control are controlled as
shown in Fig.7-2-4.
Fig. 7-2-4
(2) The microcontroller turns the compressor on and
off at the regular intervals (4 to 6 minutes).While
the compressor is turning off, the indoor fan motor
operates in the SUPER LOW position.
The pattern of operation depending on the relation
between room temperature and preset
temperatures is shown in Fig. 7-2-5.

7-3. Hi POWER Mode
([Hi POWER] button on the remote
control is pressed.)
When [Hi POWER] button is pressed while the indoor
unit is in Auto, Cooling, Hi POWER mark is indicated
on the display of the remote control and the unit
operates as follows.
(1) Automatic operation
•The indoor unit operates in according to the
current operation.
(2) Cooling operation
•The preset temperature drops 3°C.
(The value of the preset temperature on the
remote control does not change.)
•If the difference between the preset
temperature and the room temperature is big,
the horizontal louver moves to the Hi POWER
position automatically.Then when the difference
between them gets smaller, the horizontal
louver returns automatically.
•FAN speed : [AUTO]
If the difference between the preset
temperature and room temperature is big, the
air conditioner operates at maximum airflow
level. If the difference between the preset
temperature and the room temperature is small,
the air conditioner operates at normal airflow
level.
•FAN speed : One of 5 levels
The air conditioner operates at normal airflow
level.
(3) The Hi POWER mode can not be set in Dry or Fan
only operation.
7-4. High-Temperature Limit Control
The microcontroller detects the indoor heat exchanger
temperature to prevent pressure of a refrigerating cycle
from increasing excessively.
The compressor and outdoor fan motor are controlled
as shown in Fig.7-4-1.
Fig. 7-4-1
7-5. Low-Temperature Limit Control
The microcontroller detects the indoor heat exchanger
temperature to prevent the indoor heat exchanger from
freezing.
The compressor and outdoor fan motor are controlled
as shown in Fig.7-5-1 and 7-5-2.
