2)H/P Model (high quality LCD remote controller supplied)
Operation Indicator
•On while in appliance operation, off while in appliance pause
•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°CC 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.
■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.
- 21 -
•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 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 (New Type 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.
•Defrost control is available 60 min. later since heating mode operation started, and it will not prolong over 12 min.
•Defrost control is carried out according to the following priority order while in heating mode operation.
1st priority : Defrost control is carried out according to the indoor pipe temp 60 min. later since heating mode operation started.
2nd priority : The temp differences between the indoor pipe temp and the intake air temp 25 min. later ( T1) and 60 min. later ( T2) since heating mode operation started are measured, then defrost control is carried out according to the difference ( T= T1T2).
3rd priority : Defrost control is carried out according to the temp difference ( TE=TE1-TE2) between the indoor pipe temperatures of 25 min later (TE1) and 60 min later (TE2) after heating mode operation started.
•When the indoor pipe temp is 41°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.
■Defrost Control (Fuzzy Rule applied)
•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 compared 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.
-22 -
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 carrying 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.
•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 control 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 => 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 temperature
■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.
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.

•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
