Google Nest thermostats are designed to work without a C wire in most homes, but for some systems, including heating-only, cooling-only, zone-controlled, and heat pump systems, you’ll need a Nest Power Connector or C wire. The Nest Power Connector is a simple, affordable alternative to a C wire if your heating and cooling system requires one to power your Nest Thermostat.
Costs less than hiring an electrician to install a new C wire through your walls
Installation is simple
It attaches to your furnace, air handler, or zone controller
It comes with simple instructions; no wiring or drilling required
The Nest Power Connector is only compatible with 24 VAC systems; it won’t work with millivolt or high voltage systems
The Nest Power Connector is the Nest thermostat C wire adaptor that’s designed specifically for Nest thermostats
The Nest Power Connector doesn’t require any new wiring or drilling. It attaches to your furnace, air handler, or zone controller and comes with simple instructions for easy installation.
And if you don’t want to install it yourself, you can always hire a pro. See how it’s installed.
