humidifire settings

I was just wondering I went into the setup screen and I shut off my humidifier last night and the setting went from 2 to C2 I know it means classic 2 what is the difference between the classic mode and regular mode of humidifier

Hi springman946,

I did a google search on the the forum pages and this was one of the first hits to come up. It is from 2010 but it explains it better than I could. Hope this helps

Classic Mode uses heat only. No room sensors for evaluating the ambient room humidity as a starting point for humidity delievery.
Typically it uses quite a bit more water than the similar setting when using the new system one humidification mode. Main drawback is rain out in hose or mask. Condensation which, while it won't hurt you it, sure is annoying. This was the way of heated humidifiers for years and years.

The default mode is the "new system one humidification system" and it utilizes sensors in the machine to figure out what the starting point ambient humidity is and then adds heat as needed to try to maintain whatever humidity level is set.
This mode uses less water and hopefully less chance of rain out. Drawback to this system is the machine doesn't heat as often and if the room is cooler temp the air going to the mask can seems cold and uncomfortable. I called it "ice cube nose". Even at the max setting when my bedroom temp is cooler my nose got painfully cold.

So then they came out with the 60 series heated hose system..taking the new system one humidification even farther by allowing better temp control of the air going to the mask without sacrificing humidity delivery. A person can alter the temperature of the air coming to the face along with humidity delivered. Much better controls that are independent of each other. I love, love mine.
But them I like LOTS of added moisture AND a cold bedroom which is a prime recipe for rain out or ice cube nose.

There are ways to add heat to the pre 60 series machines hoses so that rain out and ice cube nose issues can be reduced.

The ResMed S9 CLimateline was the first heated hose option that was an built in to the cpap machine...the 60 series was Respironics answer to the ClimateLIne system. Not everyone needs or wants the heated hose system but those of us who like lots of added moisture and cooler bedroom temps have found that either system is much appreciated.
