    "Easy gadget to make ac thermostat work c-wire power adapter"

    See all customer reviews

    Product Description

    The C-Wire provides a continuous flow of power to operate more advanced 24-Volt thermostats and is most often needed when upgrading to Wi-Fi and wireless thermostats. The C-Wire Power Adapter converts existing thermostat wires to common wires (C-Wires) to help make Honeywell Home Smart Thermostats compatible with homes that may be missing this "common" wire. Features easy push terminals and an adhesive mount to attach the adapter to the outside of your furnace, while a closed cover conceals internal components — making installation quick and easy.
