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 the Remote Control is turned ON.

•

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)

▲

T = Intake air temperature - Indoor heat exchanger temperature

This is to protect reverse rotation of the compressor when there is a instantaneous power failure.

Anti-Dew Formation Control

Purpose is to prevent dew formation on indoor unit air discharge area.

•

When the following conditions accur 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 Contro l 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.

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 SLo 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.

Time Delay Safety Control

Once the compressor stops, it will not start for 3 minutes during Cooling operation.

•

Starting Current Control

Same as Starting Current Control for Cooling Mode operation.

•

Anti-Freezing Control

Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor

•

stops.)

Compressor Reverse Rotation Protection Control

Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting

•

is valid during compressor stops.)

Anti-Dew Formation Control

Same as Anti-Dew Formation Control for Cooling Mode operation.

•

Automatic Fan Speed Mode

When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.

Fan speed off and on at SLo speed.

•

Deodorizing Control.
