looking to swap a Trane thermostat tcont824as52da

[lewisdavisjr]

I have the Trane thermostat with wires on the W1, BK, G, Y1, O and RH. I have changed another thermostat but this one has the wire on the BK and the others didn't. Not sure if this setup is compatible with the nest. Its a heat pump.

Hi lewisdavisjr,

Thank you for reaching out to our community.

I appreciate you letting us know that you have a Trane thermostat with wires on the W1, BK, G, Y1, O, and RH and have changed another thermostat that has the wire on the BK that the other didn’t have. I understand that you need to know if this setup is compatible with the Nest.

Before I start further troubleshooting, let me ask you a few questions:

• Could you please let me know the model of your Nest thermostat?
• Could you please take a picture of the Trane thermostat wires before you remove it from the wall and post it here?

If it is possible, I will also appreciate you posting a picture of the wires that are in the control board.

Thanks for your kind attention; I will be looking forward to your answer.

Best regards,

Virna

Hi lewisdavisjr,

Thank you for your kind response. I appreciate the effort you invested in sharing with me the pictures and the information required. All that information helped me to do my research to provide you with accurate assistance.

Since your setup is incompatible with the Nest thermostat, it will require a Nest Pro technician's assistance to check the compatibility. Please get in touch with them.

Thanks for your kind attention. Feel free to keep us posted if you have more questions.

Best regards,

Virna
