12.2 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 -1.5°C from 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
turned "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.
