Installation is simple; the Nest Power Connector attaches to your furnace air handler, or zone controller and comes with simple instructions.
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
Operating Temperature 22° to 140 (30° to 60). Made with 46% post-consumer recycled materials.
