• Flashing while in disconnection or short in Thermistor. (3 sec off / 0.5 sec on)
Sleep Timer Indicator
• ON while in sleep timer mode, OFF when sleep timer cancel or appliance operation pause.
Timer Indicator
• ON while in timer mode (on/off), OFF when timer mode is completed or canceled.
Defrost Indicator
• OFF except when hot start during heating mode operation or while in defrost control.
■
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 control. While in compressor
not running, operating with the low airflow speed regardless of the setting.
■
Healthy Dehumidification Mode
• When the dehumidification operation input by the remote control is received, the intake air temperature is
detected and the setting temp is automatically set according to the intake air temperature.

• While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C, when above 28°C , it
operates with the low or setting airflow speed. When the indoor pipe temp is between 20°C and 28°C, it oper-
ates with Super-Low(while in sleep mode, with the medium airflow speed).
ates with Super-Low(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
outdoor 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 the outdoor unit from freezing,
reversed to cooling cycle to defrost the evaporator pipe of the outdoor unit.
• After 40 min heating mode operation, at 4 min interval, whether to carry out defrost control or not and the time
of defrost control are determined according to the following conditions.
1) While in heating mode operation, the maximum of the indoor pipe temperature is measured and it is com-
pared with the present indoor pipe temperature to get the difference of the indoor pipe temperatures (=the
maximum temperature of indoor pipe ? the present temperature of indoor pipe), according to which, whether
to carry out defrost control or not is determined.
maximum temperature of indoor pipe ? the present temperature of indoor pipe), according to which, whether
to carry out defrost control or not is determined.
2) According to the need of defrost control shown above and the elapsed time of heating mode operation at that
moment, the defrost control time is determined.
3) When the determined time of defrost control is below 7 min, heating mode operation continues without carry-
ing out defrost control. According to the procedure stated above, the determination is made again. When the
defrost control time is 7 min or longer, defrost control is then carried out.
defrost control time is 7 min or longer, defrost control is then carried out.
• While in defrost control, the minimum temp of the indoor pipe is measured and it is compared with the present
temp of the indoor pipe to get the difference of the indoor pipe temperatures (=the present temperature of the
indoor pipe ? the minimum temperature of the indoor pipe). When the difference is 5°C or higher, defrost con-
trol is completed and heating mode operation is carried out.
indoor pipe ? the minimum temperature of the indoor pipe). When the difference is 5°C or higher, defrost con-
trol is completed and heating mode operation is carried out.
• While in defrost control, if the defrost time determined before the start of defrost control is completed, defrost
control stops and heating mode operation is carried out regardless of the above condition.
• When the indoor pipe temp is 42°C or above, defrost control is not carried out even if the condition is one of
the defrost conditions above.
• While in defrost control, the compressor is on and the indoor fan, the outdoor fan, and the 4 way valve are off.

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

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.
