With the regular hose, I just set the humidifier setting to 4.5 (and leave it there). I assume my humidifier works because the water level is lower in the morning -- curious to know why you think the humidifier is not working for you.
There's lots of playing around to be done to find the right settings for you. I suffered very badly with sinus problems with the climateline hose and tried every possible combination I could think of. I switched to the slimline hose and my only complaint was a very dry nose. I went back to the climateline as I wanted to try the pass-over/pass through method, that worked. But still suffered with a slightly dry nose. I've found the perfect solution for me, temperature on 19C which is about 66F and humidity setting on 2....works a treat, no more sinus headaches, bunged sinus's and no more dry nose, the water level doesn't drop either as it's obviously not enough heat so it's the pass-over method with a slight twist.
When you use the heated hose, the hose feels warm for a while, but then doesn't - however, if the water from the chamber is used up over the night, it must be working. If you don't feel any drops of cold water on your nose/face during the night, it's working. Good luck.
