Horrible Overshoot
Posted: Tue Apr 05, 2011 9:46 pm
Using the JLD-612 in a brewery. Need to control mash temps to a fized temperature, say 154F. When I finished wiring the system up and testing with a sanitizing solution, the temp rise was great. 50F to 80F at 1F/30seconds, when the PID controller finally went to 100% and not a 50% duty cycle, cycling the SSR.
My issue is that I had horrible overshoot. Shot 10F above the desire 80F (SV). Not acceptable. I know the manual has overshoot directions, but I am looking for some plain english on how to set the P, I and D.
Controlling a 1500W water heater element with mash being circluated in the brewery. Need to hold temps at +/- 1F, 144F to 158F range of temps for the mash. Thanks for your help! Brewing in two days!! Help!
