Honeywell C-Wire Power Adapter

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 Home, and the Amazon thermostats.
