If your want to use this operation, press the Auto Restart Button.
Power(Forced Operation)
• Operation starts, when this button is pressed and stops when you press the button again.
■ Cooling Mode Operation
• When the intake air temperature reaches 0.5°C below the setting temp, the compressor and the outdoor fan stop.
• When it reaches 0.5°C above the setting temp, they start to operate again.
Compressor ON Temp=> Setting Temp+0.5°C
Compressor OFF Temp => Setting Temp-0.5°C
• While in compressor running, operating with the airflow speed set by the remote controller. While in compressor
not running, operating with the low airflow speed regardless of the setting.

Operation Details
■ Healthy Dehumidification Mode
• When the dehumidification operation input by the remote controller is received, the intake air temperature is
detected and the setting temp is automatically set according to the intake air temperature.
26°C
≤ Intake Air Temp => 25°C
24°C
≤ Intake Air Temp < 26°C => Intake Air Temp-1°C
18°C
≤ Intake Air Temp < 24°C => Intake Air Temp-0.5°C
Intake Air Temp < 18°C => 18°C
• While in compressor off, the indoor fan repeats low airflow speed and pause.
• While the intake air temp is between compressor on temp. and compressor off temp., 10-min dehumidification
operation and 4-min compressor off repeat
Compressor ON Temp. => Setting Temp+0.5°C
Compressor OFF Temp. => Setting Temp-0.5°C
• In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.
■ Heating Mode Operation
• When the intake air temp reaches +3°Cabove the setting temp, the compressor is turned off. When below the
setting temp, the compressor is turned on.
Compressor ON Temp. => Setting Temp.
Compressor OFF Temp. => Setting Temp.+3°C
• While in compressor on, the indoor fan is off when the indoor pipe temp. is below 26®¨C , when above 28°C , it
operates with the low or setting airflow speed (while in sleep mode, with the medium airflow speed).
• While in compressor off, the indoor fan is off when the indoor pipe temp is below 33°C , when above 35°C , it
operates with the low airflow speed.
• If overloaded while in heating mode operation, in order to prevent the compressor from OLP operation, the out-
door fan is turned on/off according to the indoor pipe temp.
• While in defrost control, both of the indoor and outdoor fans are turned off.
■ Defrost Control
• While in heating mode operation in order to protect the evaporator pipe of outdoor unit from freezing, reversed
to cooling cycle to defrost the evaporator pipe of the outdoor unit.
• Defrost control is available 30 minutes later since heating mode operation started, and it will not polong over 6
minutes.
• Deicing starts only when the outdoor pipe temperature falls below -6°C after 30 minutes passed from starting of
heating operating and more than 10 minutes operation of compressor.
• Deicing ends after 6 minutes passed from starting of deice operation or when the outdoor pipe temperature rises
over 12°C even if before 6 minutes.
■ Fuzzy Operation (C/O Model)
• According to the temperature set by Fuzzy rule, when the intake air temp is 0.5°C or more below the setting
temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is turned on.
Compressor ON Temp => Setting Temp+0.5°C
Compressor OFF Temp => Setting Temp+0.5°C
• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the
intake air temp at that time.

26°C
≤ Intake Air Temp => 25°C
24°C
≤ Intake Air Temp<26°C => Intake Air Temp+1°C
22°C
≤ Intake Air Temp<24°C => Intake Air Temp+0.5°C
18°C
≤ Intake Air Temp<22°C => Intake Air Temp
Intake Air Temp<18°C => 18°C
• When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the
Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature
automatically according to the Fuzzy rule.
automatically according to the Fuzzy rule.
• While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the tempera-
ture
■ Fuzzy Operation (H/P Model)
• When any of operation mode is not selected like the moment of the power on or when 3 hrs has passed since
the operation off, the operation mode is selected.
• When determining the operation mode, the compressor, the outdoor fan, and the 4 way valve are off and only
the indoor fan is operated for 15 seconds. Then an operation mode is selected according to the intake air temp
at that moment as follows.
at that moment as follows.
24°C
≤ Inatake Air Temp => Fuzzy Operation for Cooling
21°C
≤ Inatake Air Temp<24°C => Fuzzy Operation for Dehumidification
Inatake Air Temp<21°C => Fuzzy Operation for Heating
• If any of the operation modes among cooling / dehumidification / heating mode operations is carried out for 10
sec or longer before Fuzzy operation, the mode before Fuzzy operation is operated.
1) Fuzzy Operation for Cooling
• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C or more below
the setting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is
turned on.

• While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the temperature.
2) Fuzzy Operation for Dehumidification
• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C or more below
the setting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is
turned on.
