Combining the answer by @pzw and the original knop, referring a bit to @AntonioMarquis : we don't have to mix the colors to get the idea of 'temparature' across. These knobs might, indeed, be hiding in dark places, so let's keep a fair amount of contrast in the graphics. Just adding some (solid) color would do the trick. I also chose light blue instead of ...

It could be a good design. A lot of times users would think an A/C temperature needed to be a specific number. The truth is that the A/C should be set to something comfortable. In an office environment this leads to people "fighting" over the A/C setting. It also leads people to set the setting when they are not supposed to. For example setting a dial to ...

Yes, it's bad design for its lack of signifiers (signs in the world that offer guidance). You can't distinguish what device it belongs to by just looking at it.

I don't ...

One-word answer would be Yes. This is definitely not the right way of depicting information and it is open to perception. When a system is designed, you need to consider user's mental model. So you are right in perceiving the bar in different ways. You approach the design with your preconceived notions, or mental model which may or may not be exactly how ...
