Yeah I'm pretty upset about it, but I think the problem isn't the thermostat, it's the "smart hub" which is necessary to drive the furnace at anything besides 0% or 100%. ...or something. I'm uncertain about these conclusions because this isn't really the kind of engineering I'm into. But I no longer trust the people who installed it, or the people who designed it, so I'm kind of on my own (it was kind of a pricy system, I can't afford to just replace it). But however bad the situation is, it's made worse by vendors trying to prevent users from tinkering. At least Lennox is ineffective at keeping me out of their dealer facing controls. The awful thing about Apple is that they're good at it.
