Hi @stevsch1012,
Thanks for reaching out to the community. I understand you're having some doubts about the compatibility between your system and the Nest Thermostat because the compatibility checker said your system was fine, but the installation then said it was not, and you want to clarify this. I appreciate the detailed information shared, including your wiring configuration. No worries, I'd be more than glad to assist you.
Based on the information you've shared, your system appears compatible with the Nest Thermostat. However, the likely source of the confusion is the jumper wire you have connecting Rh and Rc. Since Nest Thermostats are designed to function without that external jumper, the installation often stops when it detects it. The solution is simple: First, remove the jumper wire entirely. Then make sure you connect only the single power line to the Rh terminal.
Please let me know how it goes after trying these steps.
Cheers,
Jonathan
