I agree that I will need support, so I think I'll be sourcing some parts from Auber after all. I just caught your own E-Brewery thread and subscribed so I can go back to it! I want to do what you did, but go RIMS without the HERMS HLT.
I think I can modify P-J's electrical diagram that you posted, but if he's listening by any chance, I'm looking for a diagram that's 30A from a mini panel with a GFCI breaker and a dryer outlet that can run a PID-controlled RIMS with a 1000w element for the MT and a 4500 or 5500 element in the Boil kettle. The BK doesn't necessarily need a second PID, I guess. Maybe just a rotary(?) switch that controls the amount of power by percentage to the BK element. 100% to reach boil, then dial it back to maintain the boil.
If anyone has seen such a diagram, please link me, because I haven't.
Thanks for all the support, I really appreciate this community!
