This thermostat has a heat/cool/off switch. It does not have an auto setting. That is SO annoying. Other thermostats have an auto setting. It should automatically switch from cool to heat as the temperature drops at night, and switch back to cool in the morning. For some reason this thermostat does not allow that. Buy a Sensi. They have an auto setting.
When my home was built I had to leave immediately for an out of state job assignment. During this time period I had no way of regulating my thermostat for the changing seasonal weather. Since setting up I can adjust my temperature 800 miles away. It gives me the outside temperature and inside temperature. Love it.
This is a nice thermostat with a lot of features. I especially like the Wi-Fi enabled control with the phone for heating/cooling/off control...and turning the back-light on for easier viewing. The display is like a really nice, cool nightlight in the room when backlit and night, and the backlight makes it easy to see in ambient daylight as well.
I love my T6 Pro Smart thermostat. I can regulate the temperature while I am away according to the weather. Soooo convenient and east to operate. I will be getting more of these thermostats for my other homes.
