So why would one buy this? If you have a simple heating and cooling system you aren't going to recoup the cost. However if you require a smarter thermostat because you have a complex HVAC system this thermostat will do the job. You can interface many heat sources and program the thermostat to use them the most efficient way possible. You can hook up stages for cooling also. The thermostat has options to hook up humidifier, dehumidifier, vent fans, and remote temp sensors. I wish it came with the outdoor temp sensor... turns out it is almost necessary if you have an electric heat pump so you don't burn it up when it is below freezing outside.
I do like some of the features of this thermostat, it has worked very well with my York Affinity modulating furnace. It has "learned" the ideal heating and cooling cycle lengths to maintain our house at the temp it does read and the "circulate" feature is absolute genius.
I wouldn't recommend spending more on this thermostat if you're expecting it to be worth the money.
I hope the new one lasts longer. Has good humidity control including frost control if you have outside thermostat option.
