The C-wire Substitute for Nest Thermostats

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. Check before you buy.

Works with 24 VAC Systems

The Nest Power Connector is only compatible with 24 VAC systems, so it won’t work with millivolt or high voltage systems.

Costs Less Than a New C Wire

The Nest Power Connector is an afforable C-wire substitue that's designed to be compatible with Nest thermostats - and costs much less than hiring an electrician to install a new C wire through your walls

The Nest Power Connector resists dust and water, and is made form 46% recycled plastic
