Too many wires on old system

Sczerny — Sun, 11 Jun 2023 20:17:51 GMT

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?

@Sczerny

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.
