13.2  Soft Dry Operation 

•

  Soft Dry operation can be set using remote control. 

•

  Soft Dry operation is applied to dehumidify and to perform a gentle cooling to the room. 

•

  This operation starts when the intake air temperature sensor reaches the setting temperature on the remote 

control. 

•

  When operation begins, Soft Dry will be switched “ON” for a maximum 10 minutes, then Soft Dry operation will be 

turn “OFF” for a minimum 6 minutes. After that, the Soft Dry operation will be “ON” and “OFF” based on the 
setting temperature as shown in figure below. 

•

  However after 3 minutes of compressor off, during Soft Dry “OFF” (within 6 minutes Soft Dry restart control), the 

indoor unit will start to operate at normal Cooling mode if the intake temperature is higher than Cooling “ON” 
point.
