Here are some pics of the control panel for my yet to be built electric HERMS rig. Two Auber PID's which im not to crazy about. They dont have much of a lip so they dont seal very tight to the panel. I was thinking of finding an O ring that fits tight around them, maybe that will help. All the LED switches are from automation direct. Green for pumps, Red for elements, clear for HLT stirrer, and Blue for water fill. One pump is a three way, recirculate, and sparge will have a float switch.
Cheers
