Nest installation

[CK2911]

I have a nest thermostat with only 6 wire connectors (Y, C, W on 1 side & other side has G, R, & OB) My old thermostat was wired like this

Blue wire - B

White wire - W2

Green - G

Black - E

Yellow - Y1

Red - R 

Brown - C 

There was an orange wire but not connected to anything. 

Someone please help me with wiring this to the 6 spots on my nest thermostat 

Thanks in advance

Chris

Hi CK2911, 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Fortunately, your thermostat wires are compatible with our Nest Learning Thermostat 3rd generation and should be wired to the Nest Learning Thermostat base as shown:

Also, here's a guide for the installation and setup of a Nest Learning Thermostat. 

Let us know if that helps.

Best,

Zoe
