F1, F2, and F3 are the strength of the fan blowing the air conditioner. F1 circulates the least amount of air, F3 the most. I generally find that if the air conditioner isn't getting the job done on F1, F2 will do it. I typically only use F3 if I just want to circulate air fast in my place for awhile. As far as what is "better" with closed vent or open, that depends on what you want to do. If you are using air conditioning on a hot day, then vent closed is better because it will cool only air circulating in your place. Vent open will allow fresh air in from outside, and if it's a really hot day, the air conditioner might have a harder time cooling off the fresh air than the circulating air inside your place (as it's continually being cooled repeatedly by your air conditioner).
