Here is a quick note on how to convert PID raw output to percentage open/close. To simplify this article, I am going to assume percent open.

To convert the raw output from the PID block into percentage open follow this equation

RAW / 16383 * 100

For example if your PID block is outputting 8000, your percentage open would be 48.83%

8000/16383 * 100 = 48.83

I hope that helps.
