I'd be happy to help guide you through this process.<BR /><BR />Most of the time, it's important to note that Nest Thermostats typically require a C wire (common wire) for consistent power supply. If you provide more details about your current wiring configuration with a photo, I may be able to offer more tailored advice.<BR /><BR />Feel free to share more information about your HVAC system, and I'll do my best to assist you further.<BR /><BR />Best regards,<BR />Mark</P> Sat, 27 Jan 2024 19:50:28 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Need-help-with-nest-thermostat-compatibility-I-do-not-have-a-C-wire/m-p/581084#M115528 Markjosephp 2024-01-27T19:50:28Z
