Recent reviews:

I own an air conditioning business and without a doubt this is the best control choice. The sensors, logs, alternatives and alerts take monitoring to another level. I have tested just about all highend thermostats in my home, the basic model of the honeywell prestige is excellent too, with its fitted wifi and awesome app. If you want to save some bucks I recommend also looking at the Vision Pro 8000, add the redlink adapter for wif. Both the IAQ and the Vision Pro an be set for active dehumidification or passive for standard bolwer configurations.

I got this thermostat because I wanted to control the heater while away from home. This package came with everything needed, as well as the equipment interface module, red link gateway, and thermostat. You need all these things, the thermostat alone won’t work. The interface of the thermostat is easy to use and full of features. The app works excellent to control remotely. I was able to install myself in about 1 hour. I replaced my present Honeywell thermostat and EIM. Wires from the present setup go to the same labels on the new equipment interface. I propose to attempt yourself, and if no luck hire a pro.

EZinstall. Just purchase a separate 24v transformer. Tech support helped me connect to web. Web interface is EZ too I’d have had to pay $800 to $1000 to get it installed by an hvac freelancer. If you have the mor common wired thermostat now it will be easier and less costly.
