does not stop within the first 60 secs.
However, it stops immediately with
remote control stop signal.
Overload Protector
• 2-Stage OLP to protect the compressor.
Overload Protector will trip when
– Temperature of compressor increases
to 120°C.
– High temperature or high current flows
to compressor.
(Refer circuit diagram for OLP
characteristic)

Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
7 minutes Time Save Control
Starting Current Control
Anti-Freezing Control
• If the temperature of the indoor heat exchanger falls
continuously below 2°C for 4 minutes or more, the
compressor turns off to protect the indoor heat exchanger
from freezing. The fan speed setting remains the same.
• Compressor will restart again when the indoor heat
exchanger temperature rises to 10°C (Recovery).
3 minutes waiting of Time Delay Safety Control is valid for
Cooling Operation.
Compressor Reverse Rotation Protection Control
8 Operation Details
8.1. Cooling Mode Operation
• When the compressor is stopped by Remote Control, it restarts after 3 minutes when it is turned ON by Remote Control.
• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
• The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
• When the compressor outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6
second later.
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid)
▲ T = Intake air temperature - Indoor heat exchanger temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.

automatically. (Time Delay Safety Control is valid).
• If the above phenomenon is repeated for 3 times, the compressor will stop totally.
• The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch.

Quiet Operation Control
(For Cooling Mode or cooling region of Soft Dry Mode)
• Purpose of this operation is to provide quite cooling operation compare to normal operation.
• When the Quiet Mode is set at the remote control, Quiet Mode LED illuminates, the sound level will be automatically decreased
2 dB (Lo), decreased 3 dB (Hi, Me), against the present sound level operation.
• Quiet setting of fan speed rpm refer to Indoor Fan Speed Control.
• Dew formation become severe at Quiet Lo cool, therefore Quiet Lo cool is operated only 1h 30 min (1h QLo, 30 min QLo + 50).
After that, it goes back to Lo cool (However Quiet LED remains on).
• Manual Airflow Direction:-
− RPM control during Lo cool
− RPM control during Hi & Me cool
• Auto Airflow Direction:-
• Quiet Mode Operation will stop if:-
− Quiet mode button is pressed again.
− Stopped by ON/OFF switch.
− Timer OFF activates.
− Powerful mode button is pressed.
− When change mode to Air Circulation mode.

8.2. Soft Dry Mode Operation
• The unit starts cooling operation until the room temperature reaches the setting temperature set on the Remote Control, and
then Soft Dry operation will start.
• During Soft Dry operation, the Indoor Fan will operate at Lo- speed.
• The operation will be switched on and off for up to 10 minutes “ON” and 6 minutes “OFF”. Once Soft Dry operation is turned
off, it stops for 6 minutes.
• Once the compressor stops, it will not start for 3 minutes during Cooling operation.
• Same as Starting Current Control for Cooling Mode operation.
• Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor
stops.)
• Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting
is valid during compressor stops.)
• Same as Compressor Protection Control for Cooling Mode Operation.
When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.
• Fan speed rotates at Lo- speed.
• Deodorizing Control.

8.3. Heating Mode Operation
• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
• When the setting temperature is reached during heating operation, the compressor stops and it will not start for 4 minutes.
• The compressor will start automatically if it has stopped for 30 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
(a) Outdoor Fan Control
• If the temperature of the indoor heat exchanger rises to 51°C, Outdoor Fan stops.
The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.
• If the indoor heat exchanger becomes 65°C or more, the compressor will stop and restart automatically.
(Time Delay Safety Control - 4 minutes waiting).
• If the compressor is operating continuously for 5 minutes or longer and temperature difference between intake air and indoor
heat exchanger is 5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid).
▲ T = Indoor heat exchanger temperature - intake air temperature.
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
• 4-way valve always ON during Heating operation. (Except Deicing operation)
• When the unit is switched to “OFF” during Heating operation, 4-way valve stay at Heating position for 5 minutes.
• When compressor stops (reaches room temperature), outdoor fan will operate for 30 seconds.
(30 seconds Forced Operation).
• When compressor stops (reaches room temperature), indoor fan will stop for 1 minutes, operate for 3 minutes, if still not yet
reaches the room temperature, indoor fan Lo- for 40 sec. after that operate at SLo speed.

Hot Start Control
Anti Cold Draft Control
When Heating operation starts, Indoor Fan will not start until the indoor heat exchanger reaches 30°C as diagram shown.
Hot Start is completed when indoor heat exchan ger rises to 39°C or over 4 minutes.
• This operation is to prevent the Cold Draft during Heating mode operation.
• The operation will start when compressor OFF (Thermo OFF) during Heating operation.
• For the first 30 sec. from compressor OFF (Thermo OFF), Indoor fan speed will operate accordingly to the Indoor heat
exchanger temperature as shown below:
• After 30 sec. from compressor OFF (thermo OFF), Indoor fan will run at SSLo speed only.
• Anti Cold Draft Control will stop when:
− Intake temperature < set temperature. (Time Delay Safety Control 4 minutes waiting is valid)
− After 30 minutes time saved control.
(refer to next page).

Deicing Control
Deice starts to prevent frosting at outdoor heat exchanger.
• Normal Deicing
Deice operations detection commences after 30 minutes of Heating operation starts or 60 minutes after previous deice
operation. If the TRS (Thermal Reed Switch) senses the outdoor piping temperature drops to -3°C (TRS CLOSE) or less for
50 sec. continuously during compressor is in operation, deice will start.
(There is no detection during Outdoor Fan stops.)
• Overload Deicing
During heating operation, if the outdoor Fan OFF duration (due to overload control) is accumulated up to 60 minutes and
after compressor starts for 1 minutes, deicing starts.
• Deicing ends when
1. 12 minutes after deicing operation starts;
2. TRS senses the outdoor piping temperature rises to 4°C (TRS OPEN).
3. Deicing will not end immediately as time delay (Td) is valid as shown below.
• Once deicing operation starts, it will not end for 60 seconds.
• After deicing operation, compressor stops for 30 seconds and 4-way valve stays at cooling position for 10 seconds.
