What type of plugs are you using for your probes, elements, and power in?
Also, what will your brewing process be? Just trying to match your front panel to process.
The probe plugs I will just use what comes with the RTD probes from Auber. The elements I'm going to use Neutrik Powerconn 32a. The pumps I just used an extension cord with the male end cut off and wired directly in. The power in is just one of these hard wired into the panel.
If your wondering about the center/MLT PID it is just for temp read-out and is not controlling anything. The left PID is for the HLT with a element and the right PID is for the BK with a element. The process is no different than any other HERMs system I suppose. Will recirc the mash through the HERMS/HLT and do a batch sparge.
