I did "fixed" with level 5 (5 was what was pre-input from the clinician). I preheated it... heard/saw nothing, so assumed it didn't work... but then I felt the bottom of the humidifier and it was warm (such that I worried it might damage my wooden nightstand)... so I assume it did work.
The air was the same temp as the previous night, so no change on the temp (perhaps heated hoses *are* the solution).
Aaaaand I got rained out all night long. Weird flapping sound in the tube somehow. Mask was half-filled with water when I removed it after 3.5 hours of sleep.
I didn't know what to do about the rainout in the middle of the night. So I just removed the whole thing and slept without it.
I guess I'll go back to adaptive.
Maybe I'll sew a cover for my tube, to help it retain a tad bit of the warmth from the humidifier.
1st time that I experienced a rainout. Middle of the night i had water in the mask when I scratched and water leaked out. I had set it at 3. The tube was wet inside so decided to hang everything to dry. Think I'll drop it to 1-2 or adaptive. AHI number was good 0.56. If the high humidity helped with keeping the nasal passages in check i might just break out the heated tube from the packaging.
