Cable compatibility check for nest thermostat

[JBarros]

Good day to all, I'd like to check compatibility of my system for the nest thermostat. Cables are not labeled, but colored, the motherboard is labeled for the cables as A, B, + and -. 

 

have a nice day all!

Hi JBarros,

Thanks for posting here in Community. To let you know, labels of A, B, + and - means that your system is proprietary. 

Proprietary systems aren’t compatible with Google Nest Thermostats. However, some proprietary systems can be rewired by a pro installer to be compatible.

Let us know if you have any other questions.

Best, 

Zoe.

Hi there,

I wanted to check and see if you managed to see the information I shared. Please let me know if you have any questions from here. I would be happy to assist and make sure you are good to go.

Thanks,

Hi!

I asked a local professional recommended by google, he said it was ok for the nest, but didn't tell me how to do it, so probably I'll have to ask him to come and do it.

Hey JBarros, 

Alright! sounds like a plan. In the meantime, I'll go ahead and lock this thread within 24 hours. If you run into any more issues in the future, please feel free to create a new thread.
