Humidifier Problems??? Respironics 960??

I have a brand new Philips Respironics BiPAP AutoSV Advance System One 960 which is a replacement for a earlier model the 950.

This is my second night and I am finding that the Humidifier seems weaker than the one on my 950 was. The old 950 seemed to put out a lot of moisture on lower settings.

Last night I turned the new 960 it up to #3 and it only used 1/2 of the tank in a 8:47 hour night.

The 950 would seem to cause rain out even on the setting #2.

At this time I have the older 950 on hand as I am getting ready to return it, BUT if there is a problem with the new 960 Humidifier I may want to keep the old one?

If the humidity in your area is high on a given night, the machine won't use as much water as it would when it's drier outside (or in, as it would be when central heating is on in winter).

i figured that but the change was over a couple of days, one day the 950 on #1 and a couple of day later the 960 on#3.

Seemed different.

It's a different model class.
In addition to the possibility of ambient humidity being a factor on water consumption the 60 series may simply be more efficient or whatever....heck, maybe they change it so that the 60 series used less. We know that the 50 series and 60 series humidifiers aren't interchangeable...maybe they did change how the 60 series worked in a small change somewhere or with the sensors.

Also pressures used affect water consumption.

No way to know for sure but if your nose is happy and water was used even though it wasn't as much as you are used to seeing be used...it's working.

I have used both the 50 and 60 series machines but I went directly to the heated hose on the 60 series and those settings are not an apples to apples comparison....but for humidity setting... I maxed out the 50 series and I maxed out the 60 series and with the heated hose...I use less water with the 60 series. As to why..I don't know but I do know my nose is happy and water is used so I know the machine works and that's all that matters to me.

Thanks now I can relax.

M SERIES HUMIDIFIER BLUE LIGHT , STARTS OUT BRIGHT THEN DIMS. NEVER HAD THIS BEFORE. WAS
WANDERING WHAT MIGHT CAUSE, MAYBE HEATER WASN'T WORKING PROPERLY. THANKS

Mine does that too, I think it dims so it does not bother your sleep in a dark room.

I think my old 950 also did that.

Same as the LCD screen going dark after a few seconds.

There are 2 ways you can the humidifier: system one mode: in which the heater plate turns on and off all night and classic mode: where the heater plate stays warm all night, thereby giving you more moisture at a lower temperature.

To see which mode you are in go under your set-up quadrant and look at you humidifier setting. If is just a number, then you are in system one mode, if it's c then a number then you are in classic mode. To get for to the other, turn system one humidifier (scrolls across the screen) on or off.

can you please clarify this last sentence? I am not sure I understand this instruction. Thanks.

Ok, went through some very old posts and figured out how to get into classic mode BUT when doing this it seems to turn off the heated hose feature. Is it possible to get into classic mode to get more heat and humidity and still have the heated tube active?

Nope, but with the heated hose...a setting of 3 for humidity setting with the heated hose attached is 90% humidity and I don't see classic mode giving you more than that without condensation if your bedroom is the least little bit cooler.
We can't go more than 100%...physics makes that impossible. Now could you maybe get 95% in classic mode with max heat of 5....maybe but there's no way to really measure it unless you can figure out some way to measure the humidity in the air at the mask level.

Classic mode was what we had for years and years before the machines with humidity sensors were release (even without the heated hose being available). My first machine was a M series machine...no humidity sensors...strictly heat and rain out was always a common complaint with any of the older machines like the Respironics M series and the Resmed S8s.

This is why I love the heated hose...I can set humidity to maximum which my nose likes and the temperature to what is comfortable and not worry about rain out unless I set the temp way low and the air can't hold the moisture. That is not much of a problem in the summer but with cooler temps in general the bedroom air gets cooler and the heated hose just doesn't get warm enough when the bedroom is a lot colder but then if it is...colder doesn't feel good on my nose anyway...so I warm it up anyway.

Thanks Pugsy, that was so helpful. I sleep with lots of cold air in the room during the winter so it will be interesting to see if the heated tube can keep up with the air temperature and prevent rainout. Do I get a hose wrapper if that starts to happen????

Yep, you can get a hose cozy if that happens but you may not need one.
In the winter my bedroom often gets below 50 degrees when it gets cold outside.
I always turn the thermostat down to 50 and the bedroom gets colder because of one tiny vent and 2 windows with one to the north and this house doesn't have much insulation (old, old farmhouse).
Last winter I didn't use a hose cozy with my heated hose and I didn't have any problem...max of 3 setting on the PR S1 humidity setting and 5 on the hose temperature setting. I have a Padacheek hose cozy available but I never needed it.
Years ago with those other machines in what is classic mode...I battled rain out every winter...and so did my husband because the racket that little bit of water in the hose..would wake him up.

Later last winter I switched over to the S9 machine in January and it's heated hose and I still avoided having to dig out the hose cozy.

It all depends on how cold your bedroom is because the heating starts with the incoming room air temp on the PR S1 heated hose.

Again a terrific and informative answer. My room setup sounds like yours so I will just wait and see what happens. Thanks for sharing your experience!
