6. DRY OPERATION
Refer to the Figure 4.
During the dry mode operation, the fan speed setting can not be changed.
When the compressor operates, the maximum value of the indoor fan speed is set as shown in Figure 8,
based on the detected temperature by the indoor heat exchanger sensor on heating mode.
When the compressor does not operate, the indoor fan motor operates [S-Lo] mode.
