    So far so good... This unit is working excellently... Hopefully it will last many years.... I would recommend it highly... Contractors should be made aware of its existence...

    Worked out great. This item is a newer design to my old box, so some rewiring was required. I'm not an electrician, just your average DYI homeowner. With average intelligence and following the wiring diagram, this was a simple job.

    I am a JW electrician. This was a fairly easy installation for me. I could see that it could be difficult for a home owner. Fired right up and worked perfectly. Thermostat is very functional.
