8 Operation Details
8.1.Cooling Mode Operation
Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
• 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.
7 minutes Time Save Control
•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.
Starting Current Control
•When the compressor outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6 second later.
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
•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)
s 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
•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.
Anti-Dew Formation Control
•Purpose is to prevent dew formation on indoor unit air discharge area.
•When the following conditions occur for 30 minutes continuously, anti-dew formation is controlled by indoor fan speed shift to low (CLo to HLo):
−Indoor intake air temperature is more than 24°C and less than 30°C.
−Remote Control setting temperature is less than 25°C.
−Compressor is on.
−Cooling operation mode.
−Indoor Fan motor operate at Low fan speed.
• This control is cancelled immediately when above condition is changed.
Automatic Fan Speed Mode
When Automatic Fan Speed is selected at Remote Control during cooling operation.
•Fan speed rotates in the range of Hi to Me.
•Deodorizing Control.

8.3.Heating Mode Operation
Heating in operation according to Remote Control setting.
Time Delay Safety Control
• 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.
30 minutes Time Save 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.
Overload Protection Control
(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.
(b)Compressor high pressure protection
•If the indoor heat exchanger becomes 65°C or more, the compressor will stop and restart automatically.
(Time Delay Safety Control - 4 minutes waiting).
Compressor Reverse Rotation Protection Control
•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).
s 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 Control
