Chiming in as we have the exact same two switches in our 4100 and this is what they told us.
White one is definitely for the AC. You have to figure our for yourself how they chose to do the positioning.
Red Switch - I saw some posts saying that this is for the Yeti Pack, I was told it is not. If you look at his panel, there is an obvious Yeti Pack switch. I was told that it has something to do with the fireplace in ours. The dealer (yes I know they are not the sages they claim they are) said that it was some sort of voltage regulator so you do not trip a breaker when running possible the water heater and the fireplace.
I have not verified the use of that red switch, but when I do, I will tell you.
I also stood and hit that fantastic fan switch for about 10 minutes saying " where the **** is that noise coming from, I know this switch works something, I can hear it."
