So I've been brewing with the BCS 460 for a while, and when I upgraded my current rig I knew that I wanted to be able to go fully automated on the burners (eventually the pumps too).
I started with an Email to Ryan over at Ebrewsupply who was tremendously helpful in assembling a DIY Kit, and schematic.
Cost and complexity was simplified by keeping everything attached to the panel (pumps, solenoids) on 110v.
4x Unswitched 110v outlets for accessories (Monitor, Wifi, Laptop, etc)
5x E-stop 110v outlets for Solenoids/pumps
2x Internal 110v outlets for BCS-460 and 6v "manual mode" powersupply. With interrupt for resetting the BCS without opening the panel.
5x Cat-5 jacks for temp probes, and external network.
