Selecting the DC fan motor taps
It is necessary to set the fan speed in accordance with the intended application and the optional parts to be
used if any such part is used. (Table 1-11-1)
If this speed is not changed, a reduction in the air flow may result, causing the air outlet temperature to drop
and condensation to form during cooling.
There are two ways to set the fan speed: either (1) change the positions of the DIP switches on the indoor unit
control PCB or (2) set the speed using the wired remote controller. Select one of these ways.
* Priority is given to setting the fan speed by changing the positions of the DIP switches.
