Help with New airsense 11 autoset humidification with heated tube in cold room

I just received an airsense 11 autoset with heated tubing (i had a dreamstation and got tired of waiting for replacement) and have had a few nights with it. The room I sleep in gets very cold at night and condensation is a problem in the winter. I first tried setting humidity to max and heated tube to a lower temp. This resulted in water in the heated tube fairly quickly. Then i switched to all auto. I find the temperature of the air to be too hot. Can anyone recommend what settings i should use to accomplish decent humidity while keeping the air not too hot. Another note is that my prescribed pressure is 6. I tried messing with a pressure range on the dreamstation but it ended up maxing out and leaking so i stopped that.
For what its worth i have had sinus problems for about 4 months using the dreamstation and i am hoping better humidification will help clear this up. Historically I have had somewhat chronic sinus problems, but not so much for the last 10 years since i started a heavy amount of fitness with CrossFit.. It came back when my gym closed due to Covid and my activity level went down. So it could be just fitness and/or cpap related.

You can adjust the heat and humidity level independently.

I'd suggest trying about a 4 humidity level, and adjust up or down from there as needed.
For temp: I don't currently have a climateline on my unit, but as I recall, auto was too warm form me too, I think I set it manually for about 75 degrees or so.
Again, you can adjust up or down as needed to be comfortable for your, but not so cool as to have rainout.

Thanks, i will give this a try. I noticed that i was out of water as well after, not sure when that happened (only used 2 nights).

Warmer air holds more moisture than colder air.

Your cold bedroom is your biggest problem. You have increase the hose air temp and find a happy medium between the amount of moisture your nose wants and your preferred hose air temp.
I am not crazy about warmer air either but I am even less crazy about a cold shower from condensation in the mask or hose or the freight train of noise I get with water in the hose.

Oh...don't expect a chamber of water to last more than one night if your ambient humidity is the least little bit on the dry side unless you maybe use a setting of 1 or 2 on the humidifier.
I am betting that your ambient humidity is on the low side in Alaska and heating of homes. Just the use of a stove or furnace will dry out the air a lot.

Thanks for the further advice Pugsy. Lots to learn and on the good side this appears to be better than my dreamstation at humification, i think the only humidification i had with that was the air going by the water. The tray would last a long time, week or more. The thread you sent is really great. Thanks for taking the time to point me in that direction. I will look into ordering a hose cover that fits my thin hose better. I used one for years with a wider hose, but this one seems to fall off with the narrow diameters.

I've been told by several DME reps that when I got a heated hose I could throw out my hose covers, like they were a bad thing or something. I've kept mine because I made them all, and love them and they help make my machine a little less "Medical" because they cover up the hose. When it comes to having a very cold room, combine a heated hose with a hose cover and I've not had any problems with rain out ever. At least not from the hose.

We've slept with the windows open when it was in the 40's outside and I had my humidity set to like 6 out of 8 with the hose temp at like 82. I've only had problems with moisture collecting inside the mask it self.

I'd try a cover first along with the heated hose, if the heat from the hose is too much, maybe insulating the hose from the outside will help so you don't have to use as much heat to get the same result, as the heated hose would be warming the air inside the hose and the small amount of air surrounding the hose inside the cover and not dissipating into your room all night.

Best of luck! Rest well

They're not telling you you don't need them because they're a bad thing, they're telling you with a heated hose you don't need a cover.

Modern day heated hoses have a thermostat in them that regulates the temperature, adding a cover to a heated hose doesn't impact the performance at all.

If you set your hose to 80 degrees, the hose will remain at about 80 degrees. If you put a cover on it, it will remain at about 80 degrees and have an identical impact on rain-out. The difference will be better power consumption, not that that's a bad thing.

Of course, that's where you should start being suspicious.

The hose cover saves energy--not much, but whatevs . . .
The hose thermostat controls the temperature,
and a little insulation could save a few pennies.
One company USED to warn against using a hose cover with their heated hose,
but then they started selling their own hose cover. You connect the dots.
