It should be exactly that simple. (I think)
. You are right, there should be only one cooling system for the freezer and the fridge uses a damper/fan to draw cool air in from the freezer side. So as I said in the OP I would hook up the single relay temp controller to the freezer to maintain a regular serving temp (38-40 degrees F) and I would use the dual stage (2 relay) temp controller to control the damper (cool air in from freezer) and what ever heat source I figure out. At least this is my understanding of how it should be done. Hence this thread which I created to make sure I was seeing things the right way. Now wiring this whole thing up may be a completely different story... Maybe I will have to start a new thread to get help figuring that out!
