On the app, NOT the thermostat, there's the screen that has the big circle with the temp in the middle. It is surrounded by a circle of little lines, which represent temperatures. Often when I look at that screen, there are two lines in bold. One will be darker and larger than the other one, but there are definitely two that are highlighted. I have asked this question on Google, every way I can think of, and I'm never led to an answer to this basic question. I see other people asking, too, and instead the answer is always about the thermostat itself.
