Easy plug and plug when upgrading the older "non-smart" version of this thermostat. Had the older version/not wifi enabled thermostat in a new home. The nice thing about Honeywell is they were forward thinking about how customers upgrading their thermostat without having to rewire the entire device. You literally pull the old one out from the back plate and plug the new one in. As easy as unplugging and replugging a cord from an electrical outlet. 5 stars! Plus it works great.
Excellent product, excellect app. It can be as easy or complex as you choose.You can get notifications when away from home and control everything remotely.
I have a single zone unit. One thermostat. Many rooms to cover. WOW! This fixes the problem for average room temps. Select which remote for balance and the wall thermostat switches there. Easy to use.
The highest you can set this thermostat is 90 degrees. During on-peak hours, if you're not home & you want to raise your thermostat to a high temperature so that it won't kick on, you can only set it to 90. If your home temperature goes above 90, which it routinely does here in Arizona, your AC will kick on & you'll bit hit with on-peak charges from your utility company. The only solution is to turn your AC unit off entirely during peak hours, which is very bad for the AC unit. My previous Honeywell thermostat could be set higher than 90, so it wasn't a problem. The 90 degree limit on this thermostat is a big drawback.
