Hello folks,

Thanks for reaching out to the Google Nest Community Forum. I'd be happy to take a look at this.

I appreciate you lending hands here with the compatibility checker, @Hollen_ar_mor.

@Dcooke1, your heat pump system is Nest Learning Thermostat-compatible. Make sure to connect your existing wires to their proper terminals to avoid incorrect wiring configuration and system setup. Here's a photo of a wiring guide for you. Let me know if you need more help.

Regards,
Mark
