Title: Poor man's PID
Post by: smokinjim on March 12, 2011, 05:01:44 AM

I used a controller and temp. sensor from an electric wall oven to control cabinet temps. I bypassed and remove the original "slider" circuit board. Temp sensor is located on right side of the cabinet, just below the second rack slide(comes in from the back). Probably not as accurate as a PID, But this setup works great!

Hey, that's great. Good thinkin' and those ribs look mighty tasty. BTW, is that the obligatory adult beverage next to the smoker in the second photo? Cooking IS thirsty work. I know from experience. ;D

That's cool..

Very innovative. I like to indulge now and then and often also. :D:D :D

Very creative! Was that oven control one with a meat probe?

that is definately a creative idea. My biggest question is if that is an oven control, can it be set below 170 degrees?

The yellow wire in front is a probe for a digital thermometer, the yellow cable in the back is for the temp. sensor. I will be glad to share the wiring diagrams...later, I just bought a house and am in the process of moving. when I get settled, I will post the details, Jim

temp range is 170-550 F, temp can also be compensated + or - 35 degrees in 5 degree increments, so theoretically, the temp could be set as low as 135 F.

How do you + or - 35 degrees? Just wondering because I have a matag oven digital controller that I would like to try this with if you get it to work.

1.Press BAKE
2.Select a temperature of 550
3.Quickly (within 5-seconds of setting 550) press and hold the BAKE button approximately 5-15‡ seconds until "00" or the previously entered temperature adjustment is displayed.

‡Pressing longer could cause an F0, F1 or F7 error to be displayed.

4.Press the UP/DOWN arrow button to change the oven temperature in 5° increments to a maximum of +/- 35°
5.Press the CLEAR or OFF button to return to normal operation.

Good idea but what I want to know is how you got those ribs looking so good. I just haven't had any luck doing ribs yet.

Ed,

Give this a try. It should get you in the ballpark then you can expand and experiment from there. http://forum.bradleysmoker.com/index.php?topic=10182.0
