    "Not compatible with all homes...I was looking forward towards having a nice wireless thermostat but quickly realized it’s not compatible with homes built prior to 1990. I have an 84 home with central air but my system does not have a dedicated power wire for this thermostat, therefore I cannot use it....I have installed six of these across multiple homes and many years now and all of them are still working perfectly.
