Humidification system question?

[PajamaGuy]

For the DS560HS - No heated tube - How does the huidifier work? Doesn't it just raise & lower the heater temp? Does it measure the room's relative humidity?
With a setting of 4, in my air-conditioned bedroom, I almost empty the water tank - so it would seem that if I were to raise the setting I'd empty the tank.
How/where does one inquiring mind find the answers?

I have the same unit. It appears there is something like a coffee maker hot plate under the water tank in the humidifier. Based on this other note, I believe there are sensors that determine when to fire up the heat.

I think that the 60 series humidifier, used without the heated hose, then becomes a regular PR S1 humidifier and there are 2 modes available. The new humidification mode which uses less water because it evaluates the ambient room humidity and the classic mode that pretty much is like the older method which was heat and lots of water.
I say I think because I haven't seen the options in the menu for the 60 series machine.
You might go into the clinical menu and see for yourself exactly what the options are for you.
It almost sounds like you are using classic mode which does use a lot of water but it also depends on how much ambient room humidity is. The new humidification method that uses the sensors to evaluate room humidity can also use a good bit of water if your room air is dry and you are using the setting of 4. So it "depends".

Are you wanting more moisture than the setting of 4 is giving you and afraid that the tank will go dry?
Then let's figure out exactly which mode is being used now...and then try to figure out the best way to add more moisture.
If you are indeed using classic mode...and have the new humidification mode available...that would work for sure because it uses less water.
If you are using the new humidification mode already...then your choices are more limited...turn setting to 5 and see what happens or get the heated hose for your machine.

So go into the clinical setup and let's see if we can figure out what mode you are using now.

Well, I did some surfin' and found in the promo for the device that the 560 is the "new" and it does measure room humidity when the System One Humidity is "on", then adjusts the heating plate to produce what you want.

BUT - In the same promo for here (CPAP.com) for the humidifier, I found the settings are OPPOSITE of what I thought. And I can't find anywhere in the manuals what the settings represent - BUT - CPAP.com sez:

System One Relative Humidity:
•Setting 1 = 80-90%
•Setting 2 = 70-80%
•Setting 3 = 60-70%
•Setting 4 = 50-60%
•Setting 5 = 40-50%

...BUT on the next page, it is written:

If set to zero “0”, the humidifier will act as a Passover Humidifier.

Accessing Humidification Settings:

1.Humidifier must be attached to the machine
2.Access the Set Up menu
3.Scroll down the menu offerings to locate: "System One Humidification"
4.If set to "On", the technology will set the amount of humidification delivered to the system based on the setting of 1 -5 with 1 being the least and 5 being the most
5.If set to "Off", the user controls the heat setting based on C1-C5 with C1 being the lowest heat and C5 being the highest heat.

...sooooo - Who knows for sure whether, when using System One Humidification, is "1" or "5" the maximum humidity? And even more, where can one find this detailed info?

Classic mode...heat only is the C1 thru C5 settings...the key being the C.

Not sure about those %. It does appear backward but I can tell you with absolute certainty from using both the old M series machines and the new PR S1 machines.... 5 is the higher humidity delivered to the nose. A setting of one dries my nasal mucosa out something awful and I am totally miserable for about 3 days. Bad experiment when I tried 1.

It says relative humidity...maybe that is ambient room humidity..perhaps they are recommending a setting of 1 if the relative humidity is 80 to 90%. With the higher relative humidity it stands to reason that not much added moisture would be needed.

FOUND IT!

Not only do they create confusing Model Names, their website navigation logic is non-existant...

Nice find!

I'm at Humidity setting 2. If I fill the water to 75%, in the morning it is around 50%. This is in Minnesota, where the relatively dewpoint has been in the 60-68 degree range, and in the indoor relative humidity has been around 50%.

I'd expect in winter in MN that I'll go through a lot more water.
