I cannot find our what these U terminals are and the corresponding connection to the Nest. I have attached a phot of the Honeywell wiring

Hi RDosch,

Thanks for reaching out. Upon checking, the U terminals for your current thermostat are for the humidifier. Google Nest Learning Thermostats are compatible with most whole-home humidifiers and dehumidifiers that work independently from your air conditioner. However, professional installation is strongly recommended. You can check this link to learn more about our Nest Pro services.

Thanks,

Edward
