When the air conditioner is set to the Auto mode by remote controller, operation starts in the optimum
mode from among the Heating, Cooling, 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 1.0°C steps.
When operation starts, indoor main fan and outdoor fan are operated for around 1 minutes.
Room temperature and outdoor temperature are sensed, and the operation mode is selected
in accordance with the table below. <Monitoring mode>

6. OUTDOOR FAN CONTROL
*
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 7 without relating to the compressor frequency.
( Table 7 : Outdoor fan speed after the defrost )

Each time the Vertical SET button is pressed, the air direction will change as follow:
At the biginning of AUTO or HEAT mode, they may stay on position 1 for a while for adjustment.
If the angle is set to position 5 - 8 for more than 30 minutes in COOL or DRY mode, the louver will autmatically
return to position 4. (*Keeping the position 5 - 8 during COOL or DRY mode may cause of condensation water drops.)
After beginning of AUTO / HEAT mode operated and automatic defrosting operation time,
the air flow will be position 1.
The airflow direction setting will temporarily become 1 when the temperature of the airflow is low at the start of
HEAT mode.
At the beginning of AUTO mode, the position you cannot change the airflow direction.

- When the temperature of HEAT airflow is low
- During autmatic defrosting operation
In AUTO mode, there is no dual fan airflow with the following.
- When the room temperatrure is under the monitoring in AUTO mode.
(Fig. 11 )
3. Setting
The position of dual fan in COOL, DRY or FAN mode can change so that the airflows further.
( For the case that the opposite wall is far from the indoor unit, and the air agitation is required.)
1. Turn off the indoor unit by pressing the “Start/Stop ” button.
2. Press the “DUAL FAN COMFORT” button for at least 5 seconds until the current “DUAL FAN”
status is displayed.
3. Press the “TEMP.” buttons to switch the setting.

4. Press the “Start/ Stop ”button to send the setting to the indoor unit. After the status is sent,
the display will automatically return to the original screen.
*If no buttons are pressed within 30 seconds after the “DUAL FAN” status is displayed, the system
returns to the original clock display. In this case, start again from setp 1.

When operation stops in the [Heating] mode, if frost is adhered to the outdoor unit heat
exchanger, the defrost operation will proceed automatically. In this time, if indoor unit operation
indicator flashes slowly (6 sec ON / 2 sec OFF), the outdoor unit will allow the heat exchanger to defrost,
and then stop.

23. VARIOUS PROTECTIONS
1. DISCHARGE GAS TEMPERATURE OVERRISE PREVENSION CONTROL
The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas
temperature.
When the discharge temperature becomes higher than Temperature , the compressor frequency
is decreased 20rps, and it continues to decrease the frequency for 20rps every 120 seconds until
the temperature becoms 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 indicator starts blinking.

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.

When the outdoor unit heat exchange sensor temperature rises to 65°C or greater the compressor is
stopped.The compressor restarst after the 140 sec, erapsed (ST). and the temperature detection starts
60 sec. erapsed after compressor started.
5. HIGH TEMPERATURE AND HIGH PRESSURE RELEASE CONTROL ( HEATING MODE )
On heating mode, the compressor frequency is controlled as following based on the detection value of the indoor
heat exchanger temperature sensor.

6. HIGH PRESSURE PROTECTION
When the pressure switch becomes OFF (Open : higher than 4.2 MPa),
the compressor is stopped.
It is released when the pressure switch becomes ON (Close : lower than 3.2 MPa)
after 140sec. of compressor stop.

7. 4 way valve protection
The 4 way valve protection operates with the following conditions.
1. When the compresspr operates for more than 20 minutes.
2. Tn (Indoor unit HEX temp) -Tb (Room temp) > 10 deg in COOL and DRY
3. Tn (Indoor unit HEX temp) -Tb (Room temp) < -10 deg in HEAT
When the above condition 1&2 or 1&3 repeat 2 times for 2 min, the compressor stops.
When the same condition repeats 5 times, the system indicates the Error code.
8. Dew water protection (Operating in COOL, DRY)
When the vertical louver is set the position 5 ~ 8, and when the operating time erapsed 30 minutes,
the louver position changes automatically to the position 4.
9. EEV shutoff protection (Operating in HEAT)
The EEV shutoff protection operates with the following conditions.
1. When the compresspr operates for more than 20 minutes.
2. Tn (Indoor unit HEX temp) -Tb (Room temp) < 4 deg
When the above condition 1 and 2 repeat 2 times in 2 min, the compressor stops.
After the ST (Restart protection), the compressor starts.

25. HUMAN SENSOR (Energy Saving)
•
• Details about detection with the human sensor
• The human sensor detects whether there are people in the room
by looking for movement by people in the room.
About the ENERGY SAVING Operation
If no one enters the room for approximately 20 minutes, the set temperature
will be automatically controlled.
(When someone comes back into the room, the human sensor will detect this,
and automatically revert to the original settings.)
