Also, you indicated that your TC is connected to terminals +11/-12. From what the PDF indicates in the diagram for models TA6/8, it looks like the TC K type probe, should be connected to terminals -9/+10.
I may be mistaken with these points, but I think you should recheck and or try out the suggestions above. Hope this might help you.
Good luck and I hope you get it working.
Your right on the TC, I wrote it down wrong it is connected to 9/10. 11/12 is constant 14 vdc. I will check the SSR tonight. It would make sense that it runs all the time if connected to NC instead of NO. Thanks for the help. Will report back.
