[Dear landshark530, if you fine tune P.I.D, temperature fluctuation shall be under 1or 2 F.
First set I=0. and D=0. Try P from a small value, say 5, and increase step by step, till temperature goes crazy, out of control. then drop P again step by step till the temperature is stable. the P value shall be 60-70% of this stable value. Then try different I and find the best value, last D. This is a trial and error practice. Different application may have different PID value.[/QUOTE]

For long cooks (5-14 hours) with temps set in the 250 to 350 range, what would be a good setting for I and D ??

Should they be changed at all?? Why was the default at 60 and 240?

Thanks
