Hey guys, I have a Gen. 3 nest thermostat in my garage. Installed with only a 2 wire system. I have only thermostat wires going to my nest thermostat. When my nest thermostat is off, my heater in my garage is trying to turn on and then quickly turns off. I have a black and white wire only. I have the white wire in the W1 slot and the black wire in the Rh slot. I went up to my heater and tested the voltage. The black wire constantly has 24v and the white wire has 2.0v. When my thermostat is off and the system goes on and off quickly the white wire receives 4.4v and then back down to the constant 2.0v. I don't know why this is happening. My old regular thermostat, when in the off position it did not try and turn on at all. When I put the heat on it fired up right away. I don't know if I can post pictures in here or not to show what I am talking about but I will try. I have to pull the face off the wall in order not to burn out my new heater. Any help would be greatly appreciated.
