■ 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 Compressor OFF Temp., the compressor is turned off.
When the intake air Temp. reaches Compressor ON Temp., the compressor is turned on.
Themo ON Temp. => Setting Temp. +2˚C
Themo OFF Temp. => Setting Temp.+4°C
• While in compressor on, when above 38°C, it operates with 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.
• 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 outdoor unit from freezing, reversed to cooling cycle to
defrost of the outdoor unit.
■ Fuzzy Operation (Outdoor unit 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.
• While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the temper-
