If I were to start again, I would have no problem doing this in a re-circulation fashion.
I started out with what everybody seemed to do in Germany, and that is replicate a brewery with agitators etc... Hand to my heart, it's not necessary. Considering the volumes we deal with it's not an issue at all. I would go for the simplest most effective method you can find.
Mashing won't make you the great beer. Great water and great fermentation, will.

The Hendi plates were the simplest solution for my constraints and what was available to me. If I were to do the same thing again I would probably recirculate like many here do, but that's the gear I had available so I kept re-using it.

Hahahaha, now I know what you meant. Sorry for not understanding immediately.

So you can control it with a switch that triggers. You can forget auto-tuning though. The only way to get them to work is by manually adjusting the PID. I posted them earlier on IIRC

Pretty straight forward. I had to tune them manually though. It'll be something like 0.5, 2800, 3 (PID) because the plates lag a bit.
Mine a are simply connected to the mains. I use the commercial 3.5kw plates from Hendi (manual plates)
For years I did the temperature manually though. I'm just getting lazy nowadays.
A recirculation system is also a nice option.
Mashing doesn't matter as much as people think. 80% is fixed by the maltster, all we do is finish what he started. Pick your malt carefully.

I think I am going to go the induction way, it seems easier and cheaper than electric elements.

i don't understand what your problem re agitator setup and oxygen control is, What is it that troubles you?

Mind going into more detail about those? I am thinking about trying to set up some sort of mash rake, not totally sure how I should go about it with LODO in mind.

The pump is stainless throughout. Speed is controlled via a VFD (frequency inverter).
The system supports no-sparge, sparge, maltase mash, step mash and the good old British reverse infusion.
Water can be boiled and re-circulated through HE and thus made available at the right temperature for dough in or extra water for the maltase mash. It would also support step infusions no problem.
Vessels are direct heated with 3.5kw commercial induction plates. Temperature is controlled via PID controllers (1/4 DIN) sporting 32 programmable segments. Thermoprobes are j-type and pt100z
With one (bi-directional flow) pump it is possible to transfer liquids from any vessel to any vessel (except from whirlpool to mash tun - makes no sense).
I don't recirculate. Instead I agitate the grain via a 30W DC motor on a variable speed controller (not a potentiometer).
From the whirlpool the wort is re-circulated via the HE until the probe shows that the temperature is equal to the temperature of the water used for the HE. At this stage a flick on the 3-way valve redirects the flow via the Maxi310 - which has an ice bank large enough to bring the wort to 5-6C immediately. This goes straight into a conical fermenter from thereon.
Hope you find it interesting.
