The C-Wire adapter kit quickly and easily powers connected Honeywell Home thermostats that require a c-wire (common wire). Easy push terminals and an adhesive mount make installation quick and easy, while the closed cover conceals internal components.

Use for Wi-Fi, 24v thermostats when a common wire is needed but not present.

Works with Resideo, Honeywell, and Amazon thermostats.
