Our previous thermostat was 13 years old. This one is amazing by comparison. It is so easy to program including easy to turn off and not disrupt the program that was already set. It still has the proper settings when you turn it back on. The colored background (we use blue) makes such a nice contrast that I can read the temperature all the way down the hall--love that! It's only been installed 3 weeks but so far, it gets an A+.
I love being able to control the thermostats from my cell phone. Away, I can tweek them to save money. At home I can change the temperature without getting up. Gotta like that!
good quality-price relation, just wondering why it takes another place weather when connecting to my home WiFi network, it also shows another time zone, i had to disconnect WiFi to make the thermostat reading actual temperature and the clock shows real time. At the end, i realized it was a same zip code from another part of the world...
All in all great product. Only thing limiting a 5 star review is that the touch screen buttons take a little effort to depress. Too much repeated presses.
I selected WiFi 9000 because a) there was another unit installed in the home I purchased, b) we had uses a similar unit in our previous residence, and c) the interface was straight forward. The shopping experience was great. I docked a star because Honeywell does not publish it API.
