Bought this so we can check our furnace is working when we are out of town - worried about a failure causing frozen pipes. Like it! But for an older gal like me a wee bit complicated on the connecting to Wi-Fi side, we got new internet service and it caused issues however the IT help on the phone was great and we are up and running again. Once you have it set up it is pretty easy to operate.
So far so good. Recomended by HAVC contractor. It has more functions than the nest it replaced, but the one thing I miss is the humidity level. This doesn't measure humidity. I like the circulate function which the nest did not have. It was a little difficult to program the WIFI, took 3 tries, but once connected it works as expected. It has a nice clean look, and seems to hold the temperature setting with only 1 degree +/- unlike the old thermostat which could be as much as 4 degrees +/-. I have not as yet tried the schedule function, but I don't really need it as I can set all functions with my phone over WIFI. I've had this for about a month now with no issues. The jury is still out as far as longevity is concerned, but the quality seems to be very good and I do not anticipate any problems. All in all I like this thermostat a lot.
Good thermostat but took some reading to get familiar with features/terminology and operation. Would like the ability to adjust deadband around setpoint.
