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

Operations according

to the commands from the indoor unit

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

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.

(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.

7-9. 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 3H 5H 9H

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)

7-10. FILTER Check lamp

When the elapsed time reaches 1000 hours, the FILTER indicator lights. After cleaning the filters, turn off the FILTER indicator.

How to Turn Off FILTER Indicator

Press [RESET] button on the indoor unit or press filter button on the remote control.

NOTE :

If [RESET] button is pushed while the FILTER indicator is not lit, the indoor unit will start the automatic operation.

When you want a temporary operation while the FILTER lamp lights, press [RESET] button to turn off the FILTER lamp.

Remarks :

Comfort sleep mode will not operate in dry mode and fan only mode.
