Do you know about the heated hose that is available?

If it is the Airsense 10 Autoset machine, you can look in My Options in the screen display of the machine. If you set the option for Climate Control to "Manual", then you would be able to set the tube temperature as well as the humidity level. There is also an option called "Run Warmup" which I just read about. According to the Resmed site, this option does the following:
"Q. What is warm-up mode?
A. The HumidAir™ heated humidifier will rise to a target temperature of 104°F over 20 minutes. The device then holds this temperature for a further 10 minutes, ready for therapy to start. If therapy does not commence in that time, the device will automatically enter cool-down mode, where it will blow a small amount of air for around 20 minutes to stop condensation forming in the device."

Do you see the options for "Climate Control" and "Run Warmup" in your My Options window? If not, there may be another setting that needs to be made in the Clinical Settings to allow more user settings to become available to you. But first, see if you can see the settings and adjust them and see if that helps.

Also, I have never tried the "Run warmup" option and I have noticed that when I first start out with CPAP at night, the air is cold for the first little while but it does warm up evenutally. Does the air never warm up for you?

Here is the clinical manual for your machine. It tells you how to change settings and other machine info. https://sleep.tnet.com/home/files/resme ... -guide.pdf
With the heated hose you have 2 choices. Auto allows the machine to determine the hose temp and adjusts the humidity for different conditions. Manual allows you to set the hose and humidity separately. This link shows you the different settings. http://www.resmed.com/us/dam/documents/ ... sa_eng.pdf

What temperature are you setting the heated hose for and what temperature is your bedroom ambient temp?
While it wouldn't be impossible for a heated hose to be faulty it sure isn't very common.
The setting of 3 is minimal humidity so you won't get much warmth in the air that goes to the hose from the humidifier setting alone.
Are you using the automatic hose heating function or setting the humidity and hose temp separately?

I'm experiencing this also...
I have been in both modes, normal and clinician modes.
I've tried the heated hose, I even manually set it to maximum temperature.
The hose starts off heating up in my hand, then gradually cools off and returns to non-heated.
With or without the heated hose, the air starts off warmer (not "warm" though) and then gets so cold that after 20 minutes to an hour, I take off the hose and set it aside.
I just tried a night with a non-heated hose -- I thought maybe the heated hose was too demanding on the electronics. The same thing happens, after a few minutes the air starts getting colder until I have to take off the hose.
Could it have to do with sleeping in a chair and being a little more upright in posture? Maybe the machine detects something about my breathing and shuts off the heating?
I've replaced the machine and the replacement is doing the same thing. The clinician wasn't very helpful, telling me to do basically what you folks say to do.
The model worked great in South Carolina where the altitude is 500 feet and its humid and warm.
But when I moved to California in the mountains at 7000 feet, where it's dry and cool... now I'm experiencing issues.
The clinician assured me they have a lot of people up here where I'm living who have no trouble with it.

What is the EPR setting? What does it do? Are there other settings for humidity / altitude / colder climates?
