Too many wires on old system

[Sczerny]

 

 

I live in Frederick MD and I am trying to install my new Google Nest onto an existing Trane system and there are too many wires. Is this system compatible with the Nest and if so do I need to call an HVAC tech to make it work?

I can't read the labels for the terminals on the original thermostat, but it looks like it has seven wires connected. This would make it only compatible with the Nest Learning Thermostat.

Post a better picture of the current thermostat wiring.

Hi there,

Thanks for posting in the Google Nest Community forum. I just want to check if you managed to see the response above. Please share with us a clear photo of your thermostat wiring. Also, you can visit this support article for more information about the compatibility.

I appreciate your help, @Patrick_Caezza.

Best,
