6 wire hook up

[Jeffreywp1]

Tried to add picture and somehow posted without text. I have 6 wires connected on old thermostat that are labeled different than more modern thermostats. The old one is a 25 year old programmable Bryant. I have 6 wires, white, yellow, green, red, orange and a gray one in the “C” spot.   The white is connected to “W” yellow to”Y” green to “G” red to “R” and orange to “O”.   This does not seem to follow the format of all the online videos show.

Hi @Jeffreywp1,

Thanks for posting in the community forum. I understand that you'd like to know the compatibility of your system with our Nest thermostat. No worries, I'm here to help you with the answer.

Based on your response and your wiring information, your system seems to be compatible with our Nest thermostat. However, if you'd like to learn more about this, I recommend checking out the compatibility checker and the following article: Nest thermostat compatibility.

Please let me know if you have any questions from here, as I'd be happy to take a closer look and assist you further.

Cheers,
Jonathan
