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

Works with 24 VAC systems: nest power connector is only compatible with 24 VAC systems， so it won't work with millivolt or high voltage systems

Installation is simple: attaches to your furnace， air handler， or zone controller， and comes with simple instructions

Costs less than a new C wire: nest power connector is an affordable C-wire substitute 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

Thoughtfully designed: nest power connector resists dust and water， and is made from 46% recycled plastic， wire connectors and sticky pad are designed for easy， mess-free installation
