I can set a range but it's been my experience that in the "summer" I need to set it to 65 cool-only. and the in "winter" I need to set it to 65 heat-only. Fall and spring are hell and I have to check the temp to know where to set it. Ranges suck and are a carryover from the old tech, I want my house to be 65, this should be possible.
I think humidity is playing a part in it but I don't want my house to get up to 70 so setting 60-70 isn't going to work and likewise, no matter the season, I don't want it to get down to 60 unless it's at night.
