DSI boards come in two “flavors”: local flame sensing and remote flame sensing.
“Local” flame sensing means there’s a separate flame sensor that is physically placed alongside the spark electrode and is sensing the flame right there at the flame.
This makes sense! I try to take lots of notes during my coursework here, and I don’t remember learning about that in this course. I completed the course since I first posted the question. Did I miss it?
Thank you very much!
