The Nest Power Connector is a simple and affordable alternative to a C wire if your heating and cooling system needs one to power your Nest thermostat.

You can install it yourself without having to add new wiring. For homes that don’t have a C wire, the Nest Power Connector is an affordable alternative. It attaches directly to your furnace, air handler, or zone controller, and it doesn’t require any new wiring. And with simple instructions, you can even install it yourself.
