I worked out how far each damper can turn and the start and stop angles of the open/close positions so it will make life a little easier in the future.

I also started to trace out the front control panel PCB because I wish to eliminate it to save space. There is not much on it so it should be easy to do. If all goes well, I will be able to interface with the back control baord behind that PCB to make everything function. A second reason I want to do it is to be able to pop the front board back on if something were to ever fail.

The white board in the top left of the picture is the one I wish to eliminate. I plan to make a 18 pin connector I can plug directly into the AC controller (green board to the right of it) to emulate the front board. The three blue boards that are stuck together are the 5K digital potetiometers that will be replacing the temperature controls and fan speed. I know the original pots were 4.7K but 5K should be plenty close enough.
