So this is for a single element e-brewery. The PID would be used in auto mode for mash and manual mode for boil. All the parts except the recepticles are from Auber.
A member on here, "P-J", has been wonderful in providing wiring info for others. I mashed up a few of his diagrams to make the attached. While I want to acknowledge him as the inspiration, I also want to be clear that the attached design has not been vetted by him.
So, does this look safe?
