Nest thermo installation

[Elmo008]

I have 2 generations of nest thermostat I’m trying to install. However, the wiring in the wall looks different from the instructions. I can provide the pictures of the thermos and the wall wiring as reference. Need some help on instructions. 

thanks

Hi there,

@Elmo008, I saw your post and wanted to chime in. Thanks for providing the photo asked by  

Patrcik_Caezza. Could you also provide a photo of the wires from your control board?

I'll look forward to your response. 

Thanks @Patrick_Caezza for your help. 

Best,

Your current system is not compatible with any of the Nest Thermostats as it requires line voltage (120Vac) and the Nests only work with 24Vac systems.

Hi Elmo008,

While most 24 V heating and cooling systems are compatible with Nest thermostats, there are some systems that aren’t compatible. You can quickly tell if you have one of these systems without having to use the Compatibility Checker or to look at your thermostat’s wiring.

Check this article for more information.

I appreciate your help @Patrick_Caezza.

Best,
