I am a a/c technician and I did not have a problem configuring for my heat pump. A home owner, for a heat pump I would highly recommend getting a technician to do your set up. The stat does exactly what they say it does. Good product for the price. Remember that they also have a very great technical support.
I needed to have a WIFI capable thermostat so that I could control it remotely. I have two homes and need to control both of them. This thermostat provides that capability along with the matching Honeywell in my second home. The matching Honeywell Home App permits easy monitoring and controls.
It works well, but is hard to read in low light. I especially like the circ setting for the fan as it helps keep the house a more uniform temperature than my old thermostat.
