The compatibility checker said Nest would work, so I bought one. Now,
when I enter the exact same wiring during the setup, it says it’s
incompatible. There’s a jumper between Rc and R.
It was connected. Since it was jumpered to To the R terminal, I just
connected the R to R and didn’t connect the orange at all. Connected
everything else like you mentioned. Thanks for the reply! Working fine
with A/C. I’ll find out in Nov how it doe...
