You screwed up big time:B You attempted to use the Tstat mount screw for a ground????? How would that be a ground screwed into WOOD?:B Find another ground source. Now that SMALL 2 wires(Red and White), those come from the Furnace. See your pic. The RED should be 12 volt positive at the furnace and at the wall tstat. Once you get a good ground verify that at the tstat. Doug
PS a Ground should be that Large BLUE wire at the wall tstat. BUT, if that wire has lost its ground, that would be your power problem, so it is best to use a good ground from another source. I usually use the GROUND pin on the 120 wall receptacle.
