I found an Omega CN7800 and would like to wire it up to control the temp for my keezer project, but I can't figure out the wiring. I've read tons of posts about Auber PIDs but can't find anything on Omegas. (Link to owners manual and picture below)
My question is where is the 'voltage in' on this PID? From the diagram it looks like the thermocouple and the voltage in go on the same terminals but that doesn't make any sense to me. Maybe I'm wrong but if anyone out there has experience with stuff like this I could use some pointers.
