Climate control query
Not sure if I have a problem, or whether this is how Jaguar systems work.
With the CC set at "auto" the fan comes on immediately at full speed when I start the car and I can only reduce it by pushing the fan buttons (which of course turns the "auto" setting off ) I can't find anyway to change things in the touch screen, but maybe I am missing something? Can't find anything in the manual
On previously owned cars with the CC set on "Auto" the fan didn't come on until the heater or chiller started to work and then the fan would come on at increasing speed, until the set temp was reached, and then reduce to a low enough speed to maintain the temp.
Thanks in advance for any help

So, spent some time punching various buttons and touch screen and got the heat working, sort of as expected. The fan now responds to temperature changes, though in an unexpected fashion - when I raise the temp. the fan slows down. Reducing the temp. increases the fan speed. This is the opposite to expectations.
Oh well. I’ll leave it for now and see if the A/c turns itself on in early summer. Thanks for all of your help

For all the Jaguars (all?), the word Auto in any of the operations means you are literally turning the WHOLE subject over to the car's judgment and governing.
In the case of Air/Climate in the cabin, Auto means the car's judgment determines "how best" to reach the temperature you've set. The car is programmed to use the FAN as much as possible to reach you temperature. It believes a LITTLE chilled air and a LOT of fan blowing is quicker and more energy-saving than a LOT of cold air pumped just on the front passengers.
The car also seems to feel that the A/C should be used as a humidity controller more than for the primary cooling job. So while the A/C goes on every time you push "Auto", the A/C is barely being used to cool you---and the blowers are being used like fans are about to go out of style.
I don't quite agree with using the two systems that way, but I must admit "Auto" does cool a hot car, or heat a cold car, faster than I used to be able to when operating everything manually.
Keep in mind, this car you're in is always trying to do things in a sneaky, energy-concious way. Does running the fan at high and the chiller at low save more energy than the other way around? It might be interesting if we could find out somehow. Check your ECO screen while using the AC on Auto, and see what it shows.
