Auber Temp overshoot
« on: January 31, 2021, 06:54:28 PM »
Hey quick question, for you guys with PIDs.  How much is your initial temperature overshoot when the smoking it ramps up to temp?
On my model 3 wifi with the stock settings ramping up to 225* I was getting 30į over then 20į under. 
I did an auto tune with a covered corningware dish
full of water.  I was able to get an initial overshoot of +15+, -10 then it would settle and hold steady but after opening the smoker even for just 30seconds to a minute it would overshoot by 10 then drop 10 below set temp.  This seems a little much.
I'm just trying to see what Is normal for you guys, once it's settled I'm within the +/- 3* but I think the overshoots are a little much .

Iíve never measured this with my 3D. I just know that I set it at my temp and I get great food afterwards.

But with that said, I know that other smokers, whether they are pellet, stick burner or electric, take time to recover to cook temp when the door is opened and the closed. The overshoot, in my thinking, could be to help get that recovery time to a minimum? Thatís just my thinking, I could be completely off on this. Did your cook come out ok? Or did the swing impact your final results?

Again, Iíve never monitored the temp swings. I know analogs have a bit of swing, but most on here with digital cookers just set it and forget it.

The cooks have been coming out fine, no complaints.  I'm not really concerned with 15-20* either way with normal smokes.  I'm mostly looking ahead for a warm smoke with fish, where I'd rather not overshoot it that high. 
I'm going to try another autotune with 3 bricks in the model 3 and see how it goes.

Are you using a secondary temp gauge or is your controller showing the overshoot?  I don't monitor the smoker temp and rely sold on the controller and have never seen it show any overshoot.

For the fish smokes, I do use a lower cook temp. I donít go with a cold smoke, but usually 175-200. If that helps for your planning.

But glad your cooks are turning out ok!

My controller and a secondary temp guage are both showing the overshoot and they're within a degree of each other.  My main concern is warm smokes, hot smokes 15* doesn't make a difference.
 I'm running an autotune right now  I actually ended up only using 2 bricks since they weighed 5lbs each and were huge.

It's been awhile since I set it up, but my Brewing PID system had specific steps on running the auto tune to eliminate over run temps.  I can't remember the details other than to run the auto tune with the same setup as I did when brewing.  So I would try running an auto tune when you have a meat load in there.  I would suggest doing a meatloaf as they smoke fast.
