In version # 3 there are additional configuration options and some general refinements to the programming/configuration interface of the thermostat that are not present in version # 1 OR # 2

The differences between the 3 versions of firmware are so significant that I can not go into all of them. There are so many more configuration options available and the Auto/Off feature of the vent, hum, dehum, etc. (as long as those terminals are activated) are all there when you choose "more" on the touchpad.
