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.

 • 

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.

 • 

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

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

 • 

Fan speed rotates at SLo speed.

 • 

Deodorizing Control.
