Good thermostat, but not what I was expecting

Verified Purchase:Yes
I bought this to replace an old Google Nest thermostat that failed. The HVAC tech who came out swore off the Nest thermostats and advised I go with a Honeywell.
Don’t get me wrong, this is a nice thermostat. It links to my phone like the nest, and allows you to obtain temps from multiple rooms via sensors. It also has a heat/cool mode that will either run AC or heat during those weird Spring or Fall days where your system doesn’t know what to run.
The one thing it doesn’t seem to do (as I was hoping) is automatically switch between emergency/auxiliary heat and standard heating based on the outside temp. It does display outside temperatures. However I have a dual fuel system that utilizes an electric heat pump for temps above 32 degrees and LP for temps below. My system is older so it does not automatically switch between the two. My old Nest thermostat would automatically adjust the heating mode based on outside temp. This was very useful since I didn’t have to go to the thermostat and manually switch it over every time the temp dipped. The new Honeywell apparently does not do this. Quite disappointed.
So, yes it’s a good thermostat. But for what I paid I was hoping it’d be a bit smarter in its technology.
I would recommend this to a friend!
