Yes, as soon as autotune ends, the temperature swings happen, and never stop. Join 1, other followers. I changed it to 1. Maureen, FYI, during an autotune session, the firmware will take the setpoint value way over the setting you made for X time and way below your setting for X time to determine the hysteresis of the device being heated and make the necessary PID calculations.
When I re-did the autotuning using for a setpoint value it worked as it should.
I put it back at 1, as that seemed more than adequate. It keeps the output switch on even though the temperature is way above the set value. I know the feeling when you don’t have any nasty green to use as tuning fodder but it’s necessary to get it right. The ones of you who deal with Delta temperature controllerssooner or later found on the situation to reset the Temperature controller to default values.
I’ll try again tomorrow and sacrifice some more beans to the cause.

So, if you display your PID settings before and after autotuning, there’s no change in the values? After autotuning, the Fuji would behave similar to what you’re describing, way under and way overshooting.
I am attempting to control my Poppery 1 with a PID. There’s nothing that will keep one up late and unable to sleep more than when our roaster is not feeling well!
Dyb ramping, I’m soaking, I’m roasting!! Or just follow the below instructions to take the DTC back to factory defaults: Tuning without beans will not allow autotune to see the true thermodynamic properties of the what’s being heated. But what happen with DTC? Some odd Artisan or TC4 problems.
I am trying to tune at f, but with no beans in the popper, so perhaps it is too volatile to tune. Default reset by Communication. I’ve been communicating with the Delta guy, I am successfully connected to my laptop, and have dttb software set up.
Contact us, and let our staff help you. After 5 seconds, the device should show as below picture. Something else that can cause wide swings with a PID controller is if your cycle time is too dtv. Select your Region Sales. I think we’re all up to speed now. The need for cache clearing get’s me every time!
Or you use the LED code of the manual to guess the protocol and address Or just follow the below instructions to take the DTC back to factory defaults: You’ll want to make sure you’re set no slower than a 1 second cycle time. Thanks for the replies.
Artisan logging temp problems. Am I using the wrong SSR? If you’re still not totally satisfied with the PID performance you might consider doing another autotune now that the cycle time is optimized. Merry Christmas to everyone!
Happy new year for you all. I’ve followed his instructions, but the results remain the same. The PID will autotune, and seems to control the temperature quite well during that 20 to 60 second period, then it just goes crazy, dropping the temperature 75 degrees, then 484 the set value by 50 degrees. Merry Christmas to all. Have a question or need any assistance that should be answered by a professional?
In this case, you have 2 options: I once tried to autotune my Fuji PID controller using a setpoint value that was within a degree or two of ctb crack. I’ve found it necessary to autotune farther into a roast where the beans are at least starting to brown.
Or you use the LED code of the manual to guess the protocol and address. Username Password Not a member yet?
