The Indoor Fan Motor is a variable speed DC motor. The
motor will vary speed with the speed of the compressor.
The speed can also be changed at the remote control
or automatically adjusted using the AUTO fan mode. When
in AUTO fan mode, the speed of the fan is calculated using
the indoor set temperature and the indoor room ambient
temperature. (Outdoor air temperature in heat mode.)
The Fan Motor is connected to the indoor control board via
PLUG CN-9.
If the remote control is non-functional, the Emergency
Button can be accessed by swinging open the front of the wall
unit. The button is located on the right side.
Pushing this button will activate AUTO MODE operation.
AUTO MODE activated with this button will maintain 75°F.
The system will stay in this mode until commands are
received by the indoor unit communication circuit via the
remote control.There is a discrepancy here. Some literature
indicates auto mode, others say cooling mode.
