The Blue Line is Fan Output. Depending on some pre-defined settings, the output will range from 0 - 100%. In my case, I have max output at 97%. I currently have min output at 60% although I cannot confirm that was the setting when I took this snapshot.
But as voltage to the fan was regulated by the PID, fan speed was adjusted.
I am in the process of performing several air-sealing mods on my kamado while I wait for a replacement pit probe, as soon as I return I will update my posts with new images and more detailed explanations.
One of the things I am looking forward to is more variation in the fan output levels. I would like to see the fan blow at more intermediate speeds to regulate the temperature more finely. I believe I will achieve this when I seal up my kamado better.
