The PRS1 heated hose setttings run from 4 degrees above ambient temperature at the lowest setting to 16 degrees above ambient temperature at its highest.
Mine has never felt warm to the touch though a setting of 4 even on a cold night with bedroom temp in the low sixties feels like being in the tropics.
I have to switch humidy modes to the System one mode and turn off the heated hose in summer. It too hot even set on 1. But its never ever been warm to the touch.
Edited to add that you might check your leak rate. If you have a high vent rate mask and a leak bordering on large leak the airflow thru the machine and up the tube will be moving to fast for the tube or the humidifier to heat it up much if at all.
I had a similar experience when I started using my P10 nasal pillow mask with my PRS1 60 series auto. I use the system one heated humidifier at 2 setting and heated tube at 2 setting. I also preheat the humidifier 20-30 minutes prior to starting the machine.
First night, it felt as if the nasal pillows were "overheating". But the feeling went away after 15 minutes.
After 3 weeks of P10, the nasal pillows don't feel like they heat up at all. I do feel a bit of humidity but that normalizes in 5 minutes tops.
Most likely, you have gotten used to the machine and humidifier and your nose is no longer surprised by the air's humidity and temp.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.
I got better results turning off System One humidity control, and going to manual. I have the humidity setting at 2, and the hose at 3, but this time of hear, the manual setting is at 4. Plenty of warmth and humidity.
As long as the hose temperature is not higher than your skin temperature, it will not feel warm. The hose temperature is controlled at the inside of the hose ( I think that holds true for P-R as well as Resmed. If not someone please correct me) and the hose is not a great thermal conductor. With the air flowing through it, the air can be warmer than the outside of the hose.
I think your hose is working OK now. I think there was something weird going on at the beginning (maybe aliens).
