I wish the HVAC controls were more manual, like a more basic car. IMO it would be more intuitive to let the user decide independently:
- where the air is to come out
- whether or not heating or cooling is to be applied (heating and cooling should be independently selected, as the user generally knows when they want heating vs cooling, although cycling based on set temp is OK)
- how fast the fan runs
- whether the air is recirculated
I find the current design distracting, having to push buttons randomly to try to get it to do what I want, to work around funny assumptions it makes like if I increase the fan speed that must mean turn on the compressor.
