7-2. 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.
The outdoor unit 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 measurement 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
(2)Role of outdoor unit controller
The outdoor unit controller receives the operation commands from the indoor controller and executes them.
∙ Compressor operation control
∙ Operation control of outdoor fan motor
∙Turning off the compressor and outdoor fan when the outdoor unit receives the shutdown command

7-2-1. 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 microcomputer, 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, it stops swinging.
7-2-2. Indoor Fan Control
The operation controls the fan speed at indoor unit
side. The indoor fan (cross flow fan) is operated by the phase control induction motor. The fan rotates in 5
stages in MANUAL mode, and in 5 stages in AUTO mode, respectively. (Table 7-2-2)
1)When setting the fan speed to L, L+, M, M+ or H on the remote controller, the operation is performed with the constant speed shown in Table 7-2-1

7-6. Hi POWER Operation
([Hi POWER] button on the remote control is pressed.)
When [Hi POWER] button is pressed while the indoor unit is in Auto or Cooling operation, 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 setting temperature drops 3°C.
(The value of the setting temperature on the
remote control does not change.)
• If the room temperature is higher than the setting temperature by 3.5°C or more, the horizontal louver moves to the Hi POWER position automatically. Then when the room temperature is 1°C less than the setting temperature the horizontal louver returns
automatically.
• FAN speed : [AUTO]
If the room temperature is higher than the setting temperature by 3.5°C or more, the air conditioner operates at maximum airflow level. If the room temperature is higher than the setting temperature by less than 3.5°C, the air
conditioner operates at normal airflow level.
• FAN speed : One of 5 levels
If the room temperature is higher than the setting temperature by 3.5°C or more, the air conditioner operates at higher consecutive airflow level. If the room temperature is higher than the setting temperature by less than 3.5°C, the air conditioner operates at normal airflow
level.
· The indoor unit's fan speed level increase 1 tap
(3) The Hi POWER mode can not be set in Dry or Fan only operation.
(4) The Hi POWER mode can memorize with timer function.

7-7. QUIET Operation
When the [QUIET] button is pressed, the fan of the indoor unit will be restricted the revolving speed at speed L− until the [QUIET] button is pressed once again (cancel Quiet mode).
Quiet mode is the system which, control the revolving speed of indoor fan to work constantly at lower than speed L. In addition, noise level of indoor unit is less than usual.
Remarks :
1. Quiet mode is unable to work in dry mode.
2. Quiet mode is appropriate to work with less cooling load condition. Because of the fan speed L− may cause not enough the cooling capacity.
7-8. ECO Operation
Cooling operation
·The preset temperature will increase 1ºC after the
ECO mode has operated for 1 hour and the temperature will increase another 1ºC after the ECO mode has operated for 2 hour. (the value of the preset temperature on the remote control does not change.)
·The indoor fan speed is depend on presetting and can change every speed after setting ECO operation.

7-9. COMFORT SLEEP Operation
Cooling operation
·The preset temperature will increase 1ºC after the comfort sleep mode has operated for 1 hour and the temperature will increase another 1ºC after
the comfort sleep mode has operated for 2 hour.
(the value of the preset temperature on the remote control does not change)
·Press the [COMFORT SLEEP] button to select this function. The comfort sleep function will be activate together with Auto shut down function. Period of operation time can be selected by re-press the [COMFORT SLEEP] button.
The period of operation time are follows.
1H

Cancel
The principles of comfort sleep mode are:
·Quietness for more comfortable. When room temperature reach setting temperature.
·Save energy by changing room temperature automatically.
·The air condition can shut down by itself automatically.(follow to operation time that selected)
Remarks :
Comfort sleep mode will not operate in dry mode and fan only mode.

7-11. Auto Restart Function
This indoor unit is equipped with an automatic restarting function which allows the unit to restart operating with the set operating conditions in the event of a power supply being accidentally shut down.
The operation will resume without warning three minutes after power is restored.
This function is not set to work when shipped from the factory. Therefore it is necessary to set it to work.
7-11-1. How to Set the Auto Restart Function
To set the auto restart function, proceed as follows:
The power supply to the unit must be on ; the function will not set if the power is off.
Press the [RESET] button located in the center of the front panel continuously for three seconds.
The unit receives the signal and beeps three times.
The unit then restarts operating automatically in the event of power supply being accidentally shut down.
