Great thread, de3isit. P-J is a rock star, no? I'm not far from you in Encinitas and would love to check out your system some time. I built my own version and tried it out this weekend. I had issues with my gas burners. Still on Hi-pressure LP as I'm not ready to go all auto just yet. Where did you get the power switches for your pumps? I've begun the control box and haven't found appropriate switches yet. I like the colors and lights to differentiate. The box I bought is 4" deep. Will that be able to accommodate the PIDs and switches? Brew more, tinker less....Thanks for the help.
