Nest thermostat only blowing heat out

[Ksmith13]

So I have a trane thermostat with 7 wires. Yellow, brown, white, red, blue, green, and orange. The nest only has 6 places to hook up the wires. When I hooked it up to the nest thermostat it would only blow heat. Is there a way to make this work.

Hi Ksmith13,

Thanks for posting in the community! Sorry to hear that your Nest Thermostat is only blowing heating. No worries, help is here! I'd like to ask you a few questions to gather more details:

1. What type of Nest thermostat do you have? 
2. Did you use the compatibility checker tool before purchasing it? 
3. Do you have a photo of your old thermostat wiring and the new one?
4. What type of system do you have? (Heat Pump or conventional type)

Keep me posted.

Regards,

Axel.
