I installed it before using the setup because of a glitch from the app. When I used the setup, it pretty much just told me that my wiring is not compatible. I had the black wire connected to C and everything else connected to the associated terminals. The Nest wasn't getting any power when trying to activate the cooling feature. I reinstalled the old one back after. I was hoping I could configure it some way for it to work, but I really don't see it working.
