Eli5: a home AC unit. The differences between “cool”, “auto”, “dry”. What is actually happening in these settings and which should I use?

Question

It’s currently 38 degrees Celsius outside.

My ac remote also has things like “I Feel”, “Health”, “Turbo”.

What do they all mean?

Answer 1

I feel uses the temperature sensor of the remote as reference instead of the ac unit’s, while health is an air ionizer which generally makes you feel more comfortable
