I did a search but couldn't find exactly what I'm thinking. I'm in the process of figuring out my partial e-HERMS brewery. I think my brewery panel will have 2 PIDS, one timer, and alarm. Nothing fancy. The HEX would be a standalone unit, not a part of HLT. Because of this smaller HEX, I would only use 120v.
My thought was after a brew session, I could unplug my HEX, pumps, etc from the control panel and move it to where my fermentation fridge is. Use the same PIDs to control the cold/hot of the fridge.
Is this feasible? I'm sure it is. A better question is if anyone has done this with PID. I read people using BCS in this way, but I think I want to go down the PID path.
I figured, I only brew so often. Often my last batch has completed fermentation before I start my next one.
