Hi Fcastro

I think I see the problem.You are breaking ground to control unit.Sorry this is a big no,no .Your temp sensor may be backfeeding a ground to the control and possibly causing damage.I would put that swtich in the power feed circut.Center post feed power,post1 control unit,post2 control unit and green wire.Then add a wire from ac cluch + to post2.Then you dont need a relay.
