Stepper Motor and Louver
Fan Motor
Emergency Button
The Stepper Motor moves the louver up and down
(09k and 12k), and also right to left (18k and 24k).
The motors can be set to move automatically or to several
fixed positions.
The Fan Motor is a variable speed DC motor. The
motor will vary speed with the speed of the compressor.
It will operate automatically or at a preselected fixed speed.
When in AUTO fan mode, the speed of the fan is calculated
using the difference between the set and room temperatures.
The fan motor is connected to the PCB at CN8 and CN9
(09k and 12k), or CN9 (18k and 24k).
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.
The system will maintain approximately 75 degrees until
the remote is reactivated, or the power is turned off and back
on.
