1 . DESCRIPTION OF EACH
CONTROL OPERATION

1-1. COOLING AND DRY OPERATION
1-1-1. COOLING AND DRY CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature,
and controls the operation speed of the compressor.
The outdoor unit operates according to the highest request capacity of indoor unit
to meet the demand capacity of all the indoor units.
The capacity control of the low request capacity indoor unit is controlled by Branch box EEV.
Minimum Maximum
( Table 1 : Compressor speed range )

AOYG45LAT8 18rps 90rps
When the start-up control finished, the outdoor unit starts the target low pressure control.
The outdoor unit selects the target low pressure within the following range,
it is decided by the highest request capacity from indoor units.
1.90MPa
1.62MPa
3.30MPa
2.33MPa
The outdoor fan speed is controlled to keep the high pressure to the constant range for stabilizing
the distribution performance.

1-2. HEATING OPERATION
1-2-1. HEATING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature,
and controls the operation speed of the compressor.
The outdoor unit operates according to the highest request capacity of indoor unit
to meet the demand capacity of all the indoor units.
The capacity control of the low request capacity indoor unit is controlled by Branch box EEV.

The outdoor fan speed is controlled to keep the low pressure to the constant range for the following reasons.
1. Frost prevention
2. Low pressure over rise prevention

1-3. AUTO CHANGEOVER OPERATION
When the air conditioner is set to the Auto mode by remote controller, operation starts in the optimum
mode from among the Heating, Cooling, Dry and Monitoring mode. During operation, the
optimum mode is automatically switched in accordance with temperature changes. The temperature
can be set between 18°C and 30°C in 1°C steps.
When operation starts, indoor fan and outdoor fan are operated for around 3 minutes.
Room temperature and outdoor temperature are sensed, and the operation mode is selected
in accordance with the table below. <Monitoring mode>
Cooling mode
25°C Heating mode
( Table 3 : Operation mode selection table )
Room temperature (TR)
TR> Ts+2°C

TR < Ts -2°C Heating
When Cooling or Dry mode was selected at and air flow mode is Auto, the air conditioner operates as follow.
The same operation as COOLING OPERATION AND DRY OPERATION of page 01-01 is performed.
When the room temperature has remained at set temperature -1.5°C, operation is automatically
switched to Dry mode.
If the room temperature reaches set temperature +2°C during Dry mode, operation returns to Cooling.
When Heating was selected at , the same operation as HEATING OPERATION of page
01-02 is performed.
When the compressor was stopped for 6 consecutive minutes by the temperature control function
after the Cooling(Auto:Dry) or Heating mode was selected at above, operation is switched
to Monitoring and the operation mode is selected again.

Each time the button is pressed, the air direction range
will change as follow:
(Function Range)
(Table9 : Recommended Operation Range)
01-12
Use the air direction adjustments within the ranges shown above.
The vertical airflow direction is set automatically as shown, in accordance with the type of operation selected.
Cooling / Dry mode : Horizontal flow
Heating mode : Downward flow ASYG07/09/12: , ASYG18/24:
When the temperature of the air being blown out is low at the start of heating operation or during
defrosting, the airflow direction temporarily becomes to prevent cold air being blown onto the body.
During use of the Cooling and Dry modes, do not set the Air Flow Direction Louver in the Heating
range ( ) for long period of time, since water vapor many condense near the outlet louvers and
drop of water may drip from the air conditioner. During the Cooling and Dry modes, if the Air Flow
Direction Louvers are left in the heating range for around 30 minutes, they will automatically
return to position .

When the swing signal is received from the remote controller, the vertical louver starts to swing.
The range of swing depends on the set airflow direction.
When the indoor fan is either at S-Lo or Stop mode, the swinging operation is interrupted

( Stop mode means Operation stop.)
During AUTO mode operation, for the first minute after start-up, air-flow will be horizontal
; the air direction cannot be adjusted during this period.

Use the air direction adjustments within the ranges shown above.
The vertical airflow direction is set automatically as shown, in accordance with the type of operation selected.

1-2. SWING OPERATION
When the swing signal is received from the remote controller, the vertical louver starts to swing.
The range of swing depends on the set airflow direction.
When the indoor fan is either at S-Lo or Stop mode, the swinging operation is interrupted
and it stops at either upper end or bottom end.
The indoor fan motor starts after the louver reaches to the setting position.
( Stop mode means Operation stop.)
