I attempted to install a Wyze thermostat upstairs where I have heat and a/c. I have a separate transformer from my air handler. So what I attempted to do was flip G and C at the air handler in the attic.
I wired My New “c” wire like the attached but i get an incorrect wiring error. Have no heat now unless I switch back to old thermostat
I had actually accidentally labeled and flipped Rh and W, but I flipped them back and get the same error. Hoping that didn’t break anything at the zone board for my heat.
