Symphony diet 22 fully functions which are automatically and can be set by remote control, which made the work easy. I set the way that it throws the air straight to my bed level and made my nights more sleepy. it has feather touch digital control panel also. the way it handles the humidity atmosphere is really amazing and refreshing. it makes my after office hours very relaxing after using this cooler. the name itself is enough is high cool technology with the ice chamber for the extra cooling. good experience with symphony air cooler.
