I have the capability to ferment (3) vessels at 11-12 gallons each and I had an idea how to ferment them all three at different temps and with a little brain-storming help from my buddy, this is what I came up with.

OK, I get the three controllers, but how does that control temps in one chamber?

Agreed. That is a [email protected] temp controller setup, but what is this magical single chamber you refer to?

-Master controller (top) drives the chest freezer (15 cu ft) down to lowest needed temp.
-Slave controllers (bottom two) heat the their respective fermentors with the DIY FermWrap from Reptile Basics . com

Concept has been proven... I lagered a batch of beer while fermenting an Ale (38*F and 62*F respectively)

See this thread for details on my ferm chamber.

It's also linked in my signature line.

Really cool builds. I read both threads and it is impressive that you can get that much of a temp difference for ales and lagers! I was glad to see someone else had the same problem I did keeping wires inserted into the STC-1000. I also wound up using pins.

Multi temp is definity a hot setup. I have a 2 temp setup but i use the low temp for serving kegs and the high temp for fermenting.

Yeah, I'm really liking it so far. In the future though, I will probably not be holding such a crazy difference in temps. I hope to batch lagers and ales together.

Huaco, any way you might lay out a step-by-step guide on this one. I really want to do this but my electrical experience has been limited to changing a couple of bad receptacles and my stc-1000 build. I laughed when I read one of your earlier post about little experience with electrical work and then in a six month span after wiring up your panel you seem completely chill offering up small tidbits on wiring here and there.
