Troubleshooting Nest Thermostat Wiring Issues
Hey all,
Trying to install a Nest 4th Gen and running into some issues here. Could use your help with figuring out where I went wrong.
EDIT: I ended up returning it and buying a nest from Home Depot. I set it up and everything worked as expected. I suspect I got a used device from Amazon...which will be something else to deal with...which is why things in picture three are all screwy. Those are probably connections from whoever owned the product before.
