Improved effect in winter and summer:

• Summer: The cold air from the A/C is heavier than the warm air in the room, so it moves downward. Adjust the louver to be permanently vertical upwards to cool the entire space.
• Winter: The warm air from the A/C is lighter than the cold air, so it tends to heat the upper part of the room first. Adjust the louver to face vertically downwards to heat the space evenly.

A device that should not be missing from any home or office!
