    C-Wire Power Adapter

    Works great once installed. The instructions are not very good.

    Reasonably priced Honeywell C Adapter.

    Product was what I needed to upgrade my Thermostat from manual switching between Heat and cool to having it switch automatically. Cost of Adapter was reasonable compared to others being offered online.

    Didn’t work for me for some reason, but since I’m not an electrician, I can’t give a bad reviews.
