Google Nest Power Connector (C-Wire Substitute)

Your Price $24.99

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
