Smart Thermostat Wiring/Install Question

[jrbuglio]

The wiring on my old thermostat has a slot labeled W-O/B. That’s not an option on the screen in the app to pick your wires. When I select W/W1 and O/B it asks me if I have a dual system. I just moved into my home and am not quite sure if it is a dual system or not. Would I just label it O/B and stick it in that slot or do I need a professional install?

Hey folks, 

It looks like we haven't heard back from the OP so I'm going to go ahead and lock the thread. If you have any further questions or concerns, feel free to create a new thread.

Hey jrbuglio,

I would be more than happy to take a closer look and assist you. Reviewing the picture sent, I am having a hard time trying to see the wire labels. Do you mind providing me with those? If you are unsure on how to install the device, you can always have a Nest Pro come out and take a closer look as well. They would be able to install that and ensure everything is working properly. Please let me know once that has been sent, and I will be happy to take a closer look.

Best regards,

Jake
