1. COOLING OPERATION
1-1 COOLING 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 frequency of the compressor.
* If the room temperature is 2°C higher than a set temperature, the compressor operation
frequency will attain to maximum performance.

When the compressor operates for 30 minutes continuously at over the maximum frequency ,
the maximum frequency is changed from Maximum Frequency to Maximum Frequency .

* When the room temperature is between +2°C to -2.5°C of the setting temperature,
the compressor frequency is controlled within the range shown in Table1.
However, the maximum frequency is limited in the range shown in Figure 1 based on the
fan speed mode and the outdoor temperature.
* If the room temperature is 2.5°C lower than a set temperature, the compressor will be
stopped.

2. HEATING OPERATION
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 frequency of the compressor.
* If the room temperature is lower by 3°C than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is higher 2.5°C than a set temperatire, the compressor will be
stopped.
* When the room temperature is between +2.5°C to -3°C of the setting temperature,
the compressor frequency is controlled within the range shown in Table2.
However, the maximum frequency is limited in the range shown in Figure 2 based on the
fan speed mode and the outdoor temperature.
( Table 2 : Compressor Frequency Range )
( Fig.2 : Limit of Maximum Frequency based on Outdoor Temperature )
* The room temperature is controlled 2°C higher than the setting temperature for 60 minutes
after starting the operation.
After 60 minutes, it is controlled based on the normal setting temperature.

4. AUTO CHANGEOVER OPERATION
When the air conditioner is set to the AUTO mode by remote control, operation starts in the optimum
mode from among the HEATING, COOLING, DRY and MONITORING modes. 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, only the indoor and outdoor fans are operated for 1 minute. After 1 minute,
the room temperature and outside air temperature are sensed and the operation mode is
selected in accordance with the table below.

When COOLING was selected at , the air conditioner operates as follow:
The same operation as COOLING OPERATION of item 1 above is performed.
When the room temperature has remained at (set temperature -1°C) for 8 minutes, operation is
automatically switched to DRY and the same operation as DRY OPERATION of item 3 above
is performed.
If the room temperature reaches (set temperature +2°C during DRY operation, operation returns to
COOLING operation.
When HEATING was selected at , the same operation as HEATING OPERATION of item 2
above is performed.
When the compressor was stopped for 6 consecutive minutes by the temperature control function
after the COOLING or HEATING operation mode was selected at above, operation is switched
to MONITORING and the operation mode is selected again.

2. SWING OPERATION
Each time the button is pressed, the air direction range will change as follow:
Cooling / Dry mode
Heating mode

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
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 more than 30minutes, they will automatically
return to position .
During Monitor operation in AUTO CHANGEOVER mode, the airflow direction automatically
becomes , and it cannot be adjusted.

10. ELECTRONIC EXPANSION VALVE CONTROL
The most proper opening of the electronic expansion valve is calculated and controlled under the
present operating condition based on the following values.
The compressor frequency, the temperatures detected by the discharge temperature sensor, the
indoor heat exchanger sensor, the outdoor heat exchanger sensor,
and the outdoor temperature sensor.
The pulse range of the electronic expansion valve control is between 60 to 480 pulses.
The expansion valve is set at 480 pulses after 110 seconds of stopping compressor.
At the time of supplying the power to the outdoor unit, the initialization of the electronic
expansion valve is operated (528 pulses are input to the closing direction).
11. TEST OPERATION CONTROL
Under the condition where the air conditioner runs, press the test run button of the remote
control, and the test operation control mode will appear. During test running, the operation lamp
and timer lamp of the air conditioner body twinkle simultaneously. Set the test operation mode,
and the compressor will continue to run regardless of whether the room temperature sensor detects.
The test operation mode is released if 60 minutes have passed after setting up the test operation.
The compressor won't enter operation status for 2 minutes and 20 seconds after the compressor is
stopped, even if any operation is given.
At the time when the air conditioner is switched from the cooling mode to heating mode, the
compressor is stopped, and the four-way valve is switched in 2 minutes and 20 seconds later after
the compressor stopped.
When the power was interrupted by a power failure, etc. during operation, the operation contents
at that time are memorized and when power is recovered, operation is automatically started with
the memorized operation contents.
When the power is interrupted and recovered during timer operation, since the timer operation time
is shifted by the time the power was interrupted, an alarm is given by blinking (7 sec ON/2 sec OFF)
the indoor unit body timer lamp.

The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas
temperature.
AS*A09 / 12LKC 104°C 101°C 110°C
When the discharge temperature becomes higher than Temperature ,the compressor frequency
is decreased 20 Hz, and it continues to decrease the frequency for 20 Hz every 120 seconds until
the temperature becomes lower than Temperature .
When the discharge temperature becomes lower than Temperature ,the control of the control of the
compressor frequency is released.
When the discharge temperature becomes higher than Temperature ,the compressor is stopped
and the indoor unit LED starts blinking.
(Table 16 : Discharge Temperature Over Rise Prevension Control / Release Temperature)

2. CURRENT RELEASE CONTROL
The compressor frequency is controlled so that the outdoor unit input current does not exceeds
the current limit velue that was set up with the outdoor temperature.
The compressor frequency returns to the designated frequency of the indoor unit at the time
when the frequency becomes lower than the release value.
