I am setting up my Nest Thermostat and receiving an error that the unit is unable to connect to WiFi. Subsequent to that, I started to receive error code 260 indicating that the Y wire was not connected. I was able to install the first Nest unit without issue, but this 2nd unit is an issue. I have reconfirmed that the Y wire is properly connected, and have followed all instructions on bouncing the WiFi, etc. Still is not working. Any suggestions? Thanks in advance...
