My current thermostat for my AC has 6 wires. Two white, two red, one blue and one green. One red and one blue are connected to C. Two white wires are connected to Y. Red is connected to Rh and green is connected to G.
This thermostat controls central air conditioning only. How do I wire my Nest Learning thermostat (3rd generation) ?

Hey JohnR9,
Thanks for reaching out and welcome to the Google Nest Community.
What is the make and model of your AC? Also, could you provide a clear photo of your original thermostat wires showing the terminal labels?
Best,
Melba

Hi JohnR9,
Thanks for being here in the Google Nest Community.
By looking at the photo, those white and blue red wires are connected to just one terminal on the old thermostat. Since we only need to have one wire to the Nest Thermostat terminal, we'd like to check how these are connected to the main terminal block on the AC unit. This way, we'll be able to tell which wire is connected to what terminal.
Thanks for the help here, Melba.
Regards,
Ryan
