1. CAPACITY CONTROL
Compressor frequency decides by capacity of an indoor unit, operation number of an indoor unit,
set temperature, room temperature and outside temperature.
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 1 : Operation mode selection table )
Room temperature (TR)
TR> Ts + 2°C

*Middle zone
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.
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.

The airflow can be switched in 5 steps such as Auto, Quiet, Lo, Me, Hi,
while the indoor fan only runs.
When Fan mode is set at (Auto), it operates on (Me) Fan Speed.
2. FAN OPERATION
3. COOLING OPERATION (Auto : Cooling)
Switch the airflow [Auto], and the indoor fan motor will run according to a room temperature,
as shown in Fig 3.
On the other hand, if switched in [Hi] [Quiet], the indoor motor will run at a constant airflow of [Cooling]
operation modes Quiet, Lo, Me, Hi.

3-1 INDOOR UNIT FAN CONTROL FOR ENERGY SAVING (Cooling mode)
Switch the airflow at cooling mode, and the indoor fan motor will run as shown in Fig.4.
It depends on the Function setting "Indoor unit fan control for energy saving."
The maximum value of the indoor fan speed is set as shown in Fig 6, based on the detected
temperature by the indoor heat exchanger sensor in heating mode.
Field setting is necessary at AR and AU type as "Cool air prevention : effective".

On the other hand, if switched in [Hi] [Quiet], the indoor fan will run at a constant airflow
of [Heat] operation modes Quiet, Lo, Me, Hi, as shown in Table 2.

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
