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
7 Operation Details
7.1. 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.

Compressor Protection Control
Automatic Fan Speed Mode
• • •
• After the compressor starts for 50 seconds but the outdoor fan motor is still OFF, the compressor will stop and restart
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.
When Automatic Fan Speed is selected at Remote Control during cooling operation.
• • •
• Fan speed rotates in the range of Hi to Me.
• • •
• Deodorizing Control.

7.2. 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.

• • •
• 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
