Looks pretty good and should work well for ya.

Just a couple comments: I'd consider making the stir motor on all the time (or on it's own switch), you'd want it on both when the wort pump is on, or the heater is on to be most effective at heat transfer from the water to the wort.

also it's usually good practice to switch the hot leg instead of the neutral leg for safety reasons. It won't effect the operation at all, but does reduce the chance for shock. The reason is, by switching the neutral, the items are still hot, but they aren't running which can mislead someone into thinking the power is off. If you switch the hot lead, then the item doesn't have AC power when it's not running.

Like I said, it's not going to affect the operation, but it's a good design habit to have.

Most excellent suggestions - many thanks! I'm about 80% through the box wiring, but it's all modular so it shouldn't be too difficult to re-route to switch the hots.

BTW, I noticed a couple of errors in the original box wiring diagram:
> The heater bulb should not go to the hot junction, rather it should be in parallel with the stir motor & heater.
> The neutral of the stir motor & heater needs to go to the neutral junction
> The temp controller neutrals should go to the NO terminal, not the NC.

Edit - corrected version now on previous page

Here is the finished schematic before switching out the SSR's. I don't know if Im going to bother redrawing it since everything is working properly.



Here is the finished panel with the monster relays....

I think I can speak for the forum at large when I say, "Holy CRAP!!"

Well, the box is all wired up and on the mashing cart. It sure looks prettier on the schematic

Believe me, the first time I power it up i'll be standing 10 feet away using a stick to flip the switch! I put a GFI outlet on the cart for the box to plug into just to be sure...if my plumbing skills are as rusty as my wiring skills i'll have mash spraying everywhere.

Success! I rigged some spare lightbulb sockets in place of the pump/heater and (after failing to realize that I had to pull the little chain on the #&@! socket) it worked!

A HUGE thank you to Shockerengr and MonsterMash for their shared wisdom, which most certainly kept me out of the emergency room
