I honestly don't see how it could be wired wrong, seeing as how it's such a simple setup and I've gone over it so many times. 4 prong 240V power cord comes in, one hot leg is run to the SSR, then out to the 3 prong input for the element. The other hot leg and ground run directly to the 3 prong...

New problem! My heating element turns on as soon as it's plugged in, whether the SSR is activated or not. Is this SSR shot already? I don't think it should be overheated as the entire thing is just being plugged in whenever I go to test it out

@LBussy I appreciate your help and input here. You pretty much nailed it exactly for what's being run. I have a 5500W heating element that's heating 8 gallons of water, no grain at the moment, to try and tune in PID parameters for future brew settings. For the plugin (PIDAutoTune) they...

Basically, I've run autotune with a couple of different settings now and it keeps failing at the end. I've done GPIO Simple & GPIO PWM, changed the lookback settings, etc. I have no problem getting to mash temp but from there it looks like it overshoots the temp by 1 or 2 degrees and holds that...

Alright, new Crydom SSR is here. But I can't get PID Autotune to work! Everything I've tried so far and it just keeps failing. Any thoughts on what to change to help??

I went out and bought a Crydom SSR that I thought was correct but now I'm not sure.. The input is 3-32V DC but I believe the output is 40A 100V VDC.. Do I need a VAC SSR for this to work properly?

Alright, so I tried a slight rewire of my setup. Ran one hot leg to the SSR which is pinned directly to the Pi (GPIO 18). Ran the other hot leg directly to the socket for my heating element. I tried re-running PIDAutotune using both GPIOPWM and GPIOSimple as the type for the actor. Both times...

Is there a better way to wire? I think I saw a wiring diagram that had the second hot wire going directly to the element. Would that work? Wouldn't that constantly run to the element, thus heating it when you don't want it to?

@jangevaa I do. It's a 5500W element and the plug it's coming from is a 4 pronged dryer cord, so one hot line goes to each SSR, I believe. Then those run to a 3-prong plug.

@jangevaa honestly just doing what my friend that had already built a CBPi with a similar setup told me to do. It's a 2 channel relay board that I use to control the 2 SSRs for my element. One pin from the pi controls it on and off. Can I use two pins to control the same heater to go on and off...

So I was doing some more reading, and it looks like PWM logic is probably best for my boil. A lot of people recommended SimpleBoilLogic plugin. One thing I noticed though is that on the website, it says that using a relay boards means that you can't used PID logic.. and I use a relay board to...

Hoping someone here can help me out. I do BIAB using CBPi 3 and have been having problems with my mash & boil processes. My mash is bad at maintaining temps and my boil is always way too strong. I did the PID Autotune process with my heater set on PID Simple and used those settings for PID Boil...
