It took a little longer than I expected to install, I had a little help from my brother-in-law, first time for him to. Had a little wiring problem, but it told me what the problem was, went to the web site looked at the pictures and fixed the problem. Worked great. We have a two story house and the thermostat is upstairs, what a dream now, I can sit at the kitchen table and adjust with my laptop. This will be great when we go away on trips.
