Hi EMD886, welcome to the forum!
Relative humidity is defined as the percentage of moisture held in the air relative to its moisture-holding capacity.
The moisture-holding capacity of air increases as the temperature rises.
So if operating the humidifier in Auto mode (that is, with Climateline hose), the moisture content of the air you are breathing will be highest using the highest hose temperature setting.
When you are operating humidifier in Manual mode but with Climateline hose, hose temperature setting will not influence how much moisture the humidifier delivers into the air, but if the hose temperature is too low there could be rain-out (condensation) inside the hose, which could encourage growth of bacteria or mold unless hose is well dried out daily by taking it off the machine and hanging it out to dry.
Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
There is another trick to dry the hose out without taking off the line - empty out the humidifier tank and put it back. Remove the data card (should be a CF card around the back) and turn off both the humidifier and the auto on settings in your program menu. Then simply let the machine run for half an hour or so, and Robert is your Uncle, you have a dry tank, hose and everything else. No risk of bacteria or mushrooms. The air passing through the system at pressure is dry enough when there is no moisture form the tank to dry out everything neatly.
As for the heavy eyes, there are two things going on - the first is that you are getting used to a new sleeping pattern, which actually can make you feel worse for a time, no worries there, it just takes a while (sleep debt is a myth, nothing more - the brain is making an adjustment to your sleeping pattern after years of having another pattern, there is nothing to "pay back"), and second, the pressure from your mask is enough to sometimes cause disturbance in the sinus and regions around the eyes, causing a heavy, sticky feeling to the eyelids. Nothing to worry about - usually it goes away, sometimes lowering the top pressure will fix that otherwise.
