1. COOLING OPERATION
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.

the compressor frequency is controlled within the range shown in Table1.
However, the maximum frequency is limited in the range shown in Fig.1 based on the indoor
fan mode and the outdoor temperature.

* 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 .

2. HEATING OPERATION
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 some degrees higher than a set temperature,
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 Table 3.
However, the maximum frequency is limited shown in Table 4 based on the fan mode.

The compressor frequency shall change according to the temperature, set temperature,
and room temperature variation which the room temperature sensor of the indoor unit body has
detected as shown in the Table 4.
However, after the compressor is driven, the indoor unit shall run at operation frequency of
61rps (09LTCB), 51rps (12LTCB), 52rps (14LTCB) for 60 seconds.

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.

5. INDOOR FAN CONTROL
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.

6. OUTDOOR FAN CONTROL
( Table 8 : Outdoor fan speed )
*The outdoor fan speed mentioned above depends on the compressor frequency.
(When the compressor frequency increases, the outdoor fan speed also changes to the higher
speed. When the compressor frequency decreases, the outdoor fan speed also changes to the
lower speed.)
*After the defrost control is operated on the heating mode, the fan speed keeps at the higher speed
as table 9 without relating to the compressor frequency.

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 Table15.
The compressor frequency, the detected temperature by the discharge temperature sensor,
the indoor heat exchanger sensor, the outdoor heat exchanger sensor, and the outdoor temperature sensor.
The expansion valve is set at 480 pulses 110seconds after the compressor had stopped.
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).

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.

11. TEST OPERATION CONTROL
[ Operation method ]
The outdoor unit, may not operate, depending on the room temperature.
In this case, keep on pressing the MANUAL AUTO button of the indoor unit for more than 10 seconds.
The Operation lamp and Timer lamp will begin to flash simultaneously during cooling test run.
Then, heating test run will begin in about 3 minutes when HEAT is selected by the remote control operation.
(When the air conditioner is running by pressing the test run button, the Operation lamp and Timer lamp
will simultaneously flash slowly.)
[ Release ]
Perform the test operation for 60 minutes.
Pressing the MANUAL AUTO button of the indoor unit for more than 3 seconds.
[ Using the Wired remote control (Option) ]
If the Operation lamp is on, press the START/STOP button to turn it off.
Press the MODE and the FAN buttons at the same time for more than two seconds
to start the test operation.
The operation lamp will light up and "o1" will be displayed on the set temperature display.
[ Release ]
Perform the test operation for 60 minutes.
Pressing the START/STOP button will stop the test operation.

15. MANUAL AUTO OPERATION (Indoor unit body operation)
When the remote control is lost or battery power dissipated, this function will work without the remote control.
When MANUAL AUTO button is set more than 3seconds and less than 10seconds, MANUAL AUTO OPERATION
will be started as shown in Table16.To stop operation, press the MANUAL AUTO button for 3seconds.
(Table16 : MANUAL AUTO OPERATION)
01-13
16. FORCED COOLING OPERATION (TEST OPERATION)
Forced cooling operation is started when press MANUAL AUTO button for 10 seconds or more.
During the forced cooling operation, it operates regardless of room temperature sensor.
Operation LED and timer LED blink at the same time during the forced cooling operation.
They blink for 1 second ON and 1 second OFF on both operation LED and timer LED (same as test operation).
Forced cooling operation is released after 60 minutes of starting operation or pressing MANUAL AUTO button
for 3 seconds.
( Table17 : FORCED COOLING OPERATION )
When FORCED COOLING OPERATION is set, the operation is controlled as shown in Table17.
Press and hold MANUAL AUTO
button for 3 ~ 10seconds
MANUAL AUTO
button
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.

10°C HEAT operation performs as below when pressing 10°C HEAT button or Weekly timer setting on the remote
controller.

( Table 18 : 10°C HEAT operation )
19. ECONOMY OPERATION
20 . HUMAN SENSOR CONTROL
The ECONOMY operation functions by pressing ECONOMY button on the remote controller.
At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation
for cooling and heating.
The ECONOMY operation is almost the same operation as below settings.
Mode Cooling/ Dry Heating
Target temperature Setting temp.+1°C Setting temp.-1°C

( Table 20 )
The HUMAN SENSOR functions by pressing SENSOR button on the remote controller.
When the sensor detects that there is no one in the room for 20 minutes or more,
it automatically changes the operation as below settings.
When someone comes back into the room, the human sensor will detect this, and
automatically revert to the original settings.

( Application range )
The sensor unit should detect when the human body (estimate: 100cmX30cm) or the object
which has more than 4 degreesC temp, difference from the background and are crossed with
1.0m/s speed in front of the sensor unit.
When the outdoor heat exchanger temperature is lower than 5°C and the all operation has
been stopped for 30 minutes, power is applied to the compressor and the compressor is heated.
(By heating the compressor, warm air is quickly discharged when operation is started.)
When operation was started, and when the outdoor heat exchanger temperature rises to 7°C or greater,
preheating is ended.
