• 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 dehumidifica-
tion operation and 4-min compressor off repeat.
Compressor ON Temp.
➲
Setting Temp+0.5°C(+0.9°F)
Compressor OFF Temp.
➲
Setting Temp-0.5°C(-0.9°F)
• In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.
■
Heating Mode Operation(H/P model)
• When the intake air temp r3°C(+5.4°F)…above 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(+5.4°F)
• While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C(68°F), when above
28°C(82.4°F) , it operates with the low or setting airflow speed. When the indoor pipe temp is between
20°C(68°F) and 28°C(82.4°F), it operates 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(91.4°F), when above
35°C(95°F) , 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(H/P model)
• Defrost operation is controlled by timer and sensing temperature of outdoor pipe.
• The first defrost starts only when the outdoor pipe temperature falls below -6°C(21.2°F) after 45 minutes
passed from starting of heating operation and more than 10 minutes operation of compressor.
• Defrost ends after 9/6 minutes passed from starting of defrost operation or after the outdoor fan operates
within max. 2 minutes 30 seconds when the outdoor pipe temperature rises over 12°C(53.6°F) even it before
12 minutes.
• The second defrost starts only when the outdoor pipe temperature falls below -6°C(21.2°F) after 45 minutes
passed from ending of the first defrost and more than 10 minutes operation of compressor.
■
Heating overload(H/P models)
• Outdoor fan ON/OFF by sensing outdoor pipe temperature.
• Outdoor fan is OFF if pipe temperature is over 6.5°C(43.7°F) and outdoor fan is ON if pipe temperature is
below 0°C(32°F).
• Outdoor fan is off if any one part is heating overload condition.
