Hello Arizonaheat,

Thank you for taking the time to let us know about your inquiry. I'd be happy to take a look at this for you.

A multi-stage heat pump with a dehumidifier is a complex system. We strongly suggest a professional installation because incorrect setup, either due to miswiring or wrong software settings, could cause weird HVAC behavior and even damage your system. Here's how you can locate technicians in your area that can help you with Google Nest products.

Feel free to let us know if you have more questions.

Regards,

Mark
