Defcon 4, you are mistaken - (Cap Q too)
The temperature in the Cabin of an A330 is not controlled from the flight Deck but from the FAP at L1
380Driver is correct.
A330 FCOM - "The flight crew uses the temperature selectors on the air panel in the cockpit to select the reference temperature which are fine tuned through the FAP for the cabin zones".... so on and so on
Get your facts right or you will look stupid.
