So today I got a new chest freezer.I have two now.This one will be a refrigerator. I wired a digital temp control to a relay and a 110v outlet so olny one freezer can be on. Unfortunately I have a 250v relay not a 110v so I'll have to wait to run it. It should make the freezer thats a fridge have priority. I will let you know how it works and upload pics.
