Exactly. I have “manual” HVAC controls in my vehicles right now, but I did have a car with an automatic one. I had that set for 21C 365 days a year, and it handled everything, including switching to defrost in cold weather. I did not touch the HVAC controls in the 3 or 4 years I owned that car. The manual controls need to get adjusted several times per trip.
