Autotune - AW-1520H V2 & Smokin It #2

[Dmorcos]

I posted this in the Auber forums first,

The way I read and understood the Auber manuals auto tune function is that you set your smoker for actual cooking conditions, turn auto tune function to on and the PID will do its thing until complete.

The SI's manual for auto tune calls it differently and as follows, I understand the reason is that the use of a meat probe can be bypassed?

Program the PID as follows:
C01 140 E01 t t01 .5
C02 225 E02 t t02 2
C03 140 E03 t t03 1
C04 0 E04 t t04 0
C05 0 E05 t t05 0
C06 0 E06 t t06 0

Am I understanding this correctly?

Also, the way I read the above is

Step 1 temp 140 for 30 min
Step 2 temp 225 for 2 hrs
Step 3 temp 140 for 1 hr.

Again, if I am correct, what is the C01 & E01 etc about. Does not make sense to me.

thanks for any clarifications and help.

I have a #2 with an Auber controller. It's a separate stand-alone controller (not one that comes pre-installed with the digital smokers) so I can't speak to the SI manual's instructions. With mine I just load the cook chamber with bricks or whatever and kick off the autotune sequence. My instructions don't mention anything about an additional program sequence as described above - I'm not sure what that would accomplish, but again I don't have the same controller.

As far as the C01 & E01 codes, I think of the "C" value as "Chamber temperature" and the "E" as "End criteria." When programming the schedule you can specify if the end criteria is an elapsed amount of time (t) or a internal temperature as measured by the meat probe (F). The time units are tenths of an hour (.5 would be 30 minutes; .2 would be 12 minutes, etc).

You read the above program correctly as

Step 1 (cook chamber temp) 140 for (time) 30 min
Step 2 (cook chamber temp) 225 for (time) 2 hrs
Step 3 (cook chamber temp) 140 for (time) 1 hr.

Let's say you added a step to the above sequence where you want the cooker to increase the temperature to 200 degrees until the internal temp of the meat was 165 degrees, and when that happens, the cooker shuts off. In this case the program would look like

C01 140 E01 t t01 .5
C02 225 E02 t t02 2
C03 140 E03 t t03 1
C04 200 E04 F F04 165 (notice here that the End criteria is now set to "F." You would change this value when programming)
C05 0 E05 t t05 0
C06 0 E06 t t06 0


I hope this makes sense.

Thanks snout. I also am using the stand alone AW-1520H. Both smoker and PID are brand new to me.

I also have both manuals that seem to not agree on the AT process. You are correct in the Auber AT is as you have listed, which means that the AT process described in the manual is for all other electric smoker and not for the Bradley because the PID is sold tuned for the Bradley.

The SI unit wants you to program the smoker in 3 steps listed above and I am still not sure which one to use.

I have emailed both SI and Auber for clarifications but have not heard from either so far.

How do the temps hold with your AT the way you tune it? And thanks again for the reply.

Hopefully you can get some clarification. FWIW I found Auber customer service to be pretty responsive.

"How do the temps hold with your AT the way you tune it?"

When I used the "free hanging" temp probe clipped to a rack the temps were within +- 5 degrees or so. This weekend I installed a wall mount (more permanent; consistent probe location) and after the auto tune process I saw +- 2 degrees on the next cook.

Again, much appreciated.
