“Easy setup! I still would suggest to get an HVAC person to do this! As far as I can tell no outdoor sensors needed! I believe it gets that information directly from your forecast in your area! I do have a weather station I compare it with and the outdoor temp and humidity is close enough!”
“It may look simple compared to some other thermostats, but don't be fooled. This is one of the most feature rich thermostats available. It can operate a heat pump with a gas furnace as backup. Something that lots of fancier looking controllers can't do. It can simultaneously have set points for heating and cooling and will auto switch between the two. It will learn how long it takes to heat and cool your house and adapt accordingly. I'm very pleased with its performance.”
