the wires are black and white on my valve. standard. i picked up a real nice 1" schneider zone valve rated for steam, 2 way, NC ...i programmed my 2 auber pid's and will have one to monitor stack temps and one for auto draw off.

the stack PID is self-explanatory from the labels, but on the draw off PID i have the main SV set for draw off temp (readout) and another high alarm buzzer set to go off 3deg over SV(draw off temp) just in case i need to increase draw off flow if/when things get hairy. the pt100 RTD is from auber and its 12" long with a 1/4" npt compression fitting, perfect for my angled draw off box port. i noticed many PID posts in the past had trouble finding rtd's long enough. well they got em now on aubers website.

the layout is very similar to Jims from smoky lake , except i added bigger LEDs for more visibility. plus my PIDs are a bit overkill for this application (auber 2352's, not 2362s) , but i am used to programming them as i use the same model for controlling my mash tun, hot liquor tank and brew kettle for making beer. one less manual to read ....

the box is a 12x12x6 watertight box from home depot , although i could have gotten away with a 8x8x4 i think. it doesnt bother me as im installing it this week next to the steam hood, out of the way and just above eye level so i can see it wherever.

i tested the valve, probes, etc with hot water by the sink, all is well. pretty cool stuff. cant wait to run some sap through her
