Hello. I purchased a Nest Learning Thermostat and I ran the the installation set up and was informed that my system is not compatible. I saw another post where a user has the same White Rogers thermostat and they were informed that their system is compatible. Their wiring differs from my set up, so I just want to see if mine is compatible as well.
C G O Y (at the bottom)
RO B RH W (along the side)
Thanks in advance!

Your current thermostat is compatible with any of the Nest thermostats.
Wiring would be like this,
Green - G to G
Yellow - Y to Y1 or Y
White - W to W1 or W
Red - R to Rc or R (jumper to RC not needed)
The "or" is for the Google Nest Thermostats wiring.
I see a blue wire that is not in use, and I strongly recommend you use it to create a C wire between the thermostat and the furnace. Just find the C terminal in the furnace, connect the blue wire to it, and then connect it to the C terminal on the thermostat.

@Patrick_Caezza , before you tell an homeowner “Just find the C terminal in the furnace, connect the blue wire to it, and then connect it to the C terminal…” make sure you add the safety notes. TURN OFF THE POWER BEFORE OPENING YOUR FURNACE. Your lack of safety is likely going to get a homeowner electrocuted.

The easiest way to check compatibility is to use the Google Nest Compatibility checker locate at
