Hello @Panzerchomp
Thanks for reaching out to our Nest community about this new installation. So sorry for all the inconvenience. Don't worry, I'm here to help you with it.
Could you share with me a picture showing the previous wiring configuration on your thermostat? With this, I can determine the correct wiring configuration.
Also, if you can tell us information about your HVAC system, that will be very useful.
Keep us posting. I'm happy to help you with your concern.
Best regards.
Douglas.
