Item 1 REX-C100 Digital PID Temperature Control 40A SSR K Thermocouple 0 to 400℃ USA - REX-C100 Digital PID Temperature Control 40A SSR K Thermocouple 0 to. Into the van and proceeded to become a grilling and smoking champion used one of these controllers and after using the auto tune feature holds within 2 degrees all day long Couldn't be. Re: PID controll values sorted. The oven is quite big - 3200x1200x1700mm, 12 electrical heating elements x 2200W, therefore the respond of the system is very slow. After several tests the results are here: PID controller REX-C100 Proportional band 72°C Integral time.

Berme Rex C100 Auto Tune
Hey everyone. Have some issues with my PID:It's a REX C100 which is frustratingly close to the CD101 except its controls are not the same. And by C100, I mean the 'C100.' It was cheap and on eBay from China. Just hoping someone has worked this out before me.
1) I can't get into the lower layers of the software... before you go to google to get your answers, I've been there. The supposed move doesn't work on this unit, and this is my second one after shipping the other back. Anyone out there know this one? Bueller?
Problem With Rex C100 Auto-tune Staying On
2) When the K-Type thermocouple is wired into the terminals, I get an 'over' PV reading. When it isn't tied in, I get a reading of 750-850. If I repeatedly tap one contact to the second terminal (other is in) I can 'manually' decrease the value. Clearly this is not a solution, just an observation. Really, it looks like a short-circuit. But, this is a BRAND NEW unit and thermocouple. Plus, this happened with the first unit as well.
Any takers? Getting desperate.

So I thought I would start a new discussion on my controller build. After seeing what @olddog had built for the other members of the forum I had to have one. At this point the build is still in the gathering mode getting all the bits and bobs that I am going to need. As some of you might know I have a dash unit and I plan on getting a 120L SD boiler to go with her just need em to be in stock again.

Rex C100 Autotune
So the over all plan is to build a console controller that is mounted on the side on the boiler on a swing arm.
also note that the picture has be designed by a engineer.
As much as this build is about building a console controller that is fully functioning it is also about over all ferness of the look of the machine. I am a welder by trade and I really appreciate metal work. Generally when I build something from still for a friend or a customer I don't cut any corners but when it comes to my own work I tend to take the root of lets just get the job done so I can get on with enjoying my time. But not this time. The gloves came off the day I paid for my SD dash unit. Every thing I do from now on that is for my stilling is going to be smick :D
So I probably should start talking about the controller. I want to run 2 elements in it. Some advise on what one's to pick would be appreciated.
I had to re wire the shed last year so I could run 3x20 amp power points. I said to the Sparky I want to run 3 welders at the same time make it happen.
I have all ready received a bunch of gear in the mail for the build PID lights buzzers switches This build wont be one of those builds that get's done over night. expect it to take a few months to get done. I also want to incorporate beer making in to the unit while I am at it as its something that I have just started to get in to. Down the track all grain. I want to have the ability to tern pumps on and off. Monitor all my stilling temps and so on. One problem I think I might have is finding the right shape SS box that I am looking for.

Another pro engineering drawing.
One last picture of what I have all ready gathered.
