So my advice would be to turn the temperature on the humidifier DOWN to reduce the difference between the room temperature and the hose/mask temperature.

Am I confused?

Turning down the heater setting to the humidifier is also an option but it also reduces the amount of humidity being delivered to the nasal mucosa and some people find that is a problem. If/when the nasal mucosa gets dried out more than it likes then the person can end up with some rather nasty and annoying symptoms. Reducing the humidity being delivered to the nasal mucosa isn't always a good option for some people.

When we turn down the heat to the humidifier plate it reduces the amount of moisture being added to the air going to the mask.

I turned the heat and humidity down. Solved. I had a bit of a dry mouth but nothing a shot of Biotene could fix. Thanks for your help!

But if there's rainout, by definition, isn't there TOO MUCH moisture?

No, it just means the air temperature has dropped below the dew point, which is the temperature at which the relative humidity is 100%.

Nope. Like loggerhead said it just means that temperature in the mask or hose isn't enough to hold onto the moisture.
Warm air will retain more moisture than cool air.

Did you know that there are people who aren't using a humidifier at all who complain of rain out in the mask which comes from the moisture in the air that they are exhaling? They certainly aren't using "too much moisture" if they aren't even using a humidifier.
They just usually are sleeping in what a lot of us would consider a "cold" bedroom for some reason.
I know one person who lives in the high desert (so very dry arid ambient conditions) and was complaining of rain out in the mask and not even using a humidifier attached so zero added moisture. The only place the moisture could be coming from is the exhaled breath and come to find out he liked a cold bedroom...like 50 degrees. The rain out was only in the mask though...wasn't enough to make it to the hose but it sure was annoying getting that cold shower out the vent holes.

I see.

I don't use a humidifier any more. The humidifier on my PRS1 died about 3 years in (manufacturer's defect) and I never quite got into the habit of filling my humidifier any more. We turn our heat very low in winter (just enough to keep the pipes from freezing and also so it doesn't take hours to warm up the house in the morning), but I never have moisture in the tube except the time I cranked up the humidifier.
