Guys, I am trying to replace the current temp control relay with something a little more precise. I've attached a schematic of the wiring for my keggerator and would really appreciate some suggestions. I was thinking along the lines of a digital display for the current temp and being able to control the compressor so my temps are within about 3 degrees of what I set it to. Thanks in advance!
my advice it to just leave it all intact and switch the mains with a temp controller. turn the built in control down low. By doing it this way you'll leave all the protective features intact, it's much easier, and shouldn't be any more expensive.
