It works, but I'd like to control the heating and AC from another location in the house with no existing wires attached. I don't really want to drill holes to link up the wires to the new location. If I were to install another thermostat, would it possible to link up the two Nests with Wifi and the old thermostat just yield control to the new thermostat?</P> Fri, 10 Jan 2025 18:06:27 GMT zf1216 2025-01-10T18:06:27Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Can-I-use-install-a-new-nest-thermostat-to-control-the-AC-Heat-in-the-house/m-p/668767#M130693 <P>Hi,</P><P><BR />I already have a Nest 3rd Generation Thermostat installed downstairs with wiring configured.
