Hello Brett!
Im sure there are alot of newbies here like me and it would be great if you could lend us a hand by sharing your experiences on how we could choose P, I and D values based on our individual setups for maximum accuracy. Auto tune works but as you mentioned, humans are better. 😀
Just for reference I have a setting of P:50, I: 0.5, D:10 for my setup with a sous vide setup yielding plus minus 0.5C consistency. Wondering if it could be even better and also minimize overshoot when coming from a more distant start temperature.
