Fan/AC remotes have some of the worst, most unexpected UX I've ever seen. I still remember an AC remote at an Airbnb I stayed at a few years ago that, instead of having temperature control buttons that said "up"/"down" or "hotter"/"colder", it had two buttons that said "too hot" and "too cold". The "too hot" button decreased the temperature setting on the thermostat and the "too cold" button increased it.

This labeling makes some sense if you stop to think about it, but I can't shake the thought that this was the first time I encountered an interface that asked me to describe how I was currently feeling, rather than me telling it what I wanted it to do.
