All S9 users - Is H5i working ??

Are you sure your H5i is working the way it should ???
Mine hasn't and there has been a sprinkling of others with concerns...

Past several nights awakened with dry throat and cold air/ so cold it hurts a little deep in your throat. House temp set for 67 deg at night and 71 deg during the day... no windows open.
Set for Auto Climate on S9 set at 82 deg... then at 76... then 68... then 86... then I'm up. Feel the plate below the tank and its cold, very cold.
Never get rainout/ moisture in tube or mask.
Uses very little water and with Humidifier always ON... I have never run out and water would last, perhaps a week, if I left it.

I replaced the H5i about 3 weeks ago when the original humidifier did the same thing.
The following week replaced the S9 to make sure that wasn't the problem.
Contacted the DME to have the ResMed rep get some answers... still waiting since last week.

This AM I did some tests:
Removed the ClimateLine to "wipe" the contacts and make sure that part was working... it registers on the S9 as being engaged.
Removed and replaced the H5i to again "wipe" the contacts... it registers on the S9 as being engaged.
(before you ask) Power outlet running full 120 volts to single outlet in good working order.

TEST #1
Set to Climate Control to ON... ClimateLine Engaged and set temp to 80 deg and turn on Flow for S9...
1. run 10 minutes at pressure with dry resistance at end of the tube
2. feel heated ClimateLine... no warmth to touch.
3. Stop S9, lift tank out and feel heater plate below... COLD, not cool, COLD

TEST #2
Set to Climate Control to ON... ClimateLine Engaged and set temp to 86 deg (Max) and turn on Flow for S9...
1. run 10 minutes at pressure with dry resistance at end of the tube
2. feel heated ClimateLine... no warmth to touch.
3. Stop S9, lift tank out and feel heater plate below... COLD, not cool, COLD

TEST #3
Set to Climate Control to ON... ClimateLine Engaged and set temp to 72 deg and turn on Flow for S9...
1. run 10 minutes at pressure with dry resistance at end of the tube
2. feel heated ClimateLine... no warmth to touch.
3. Stop S9, lift tank out and feel heater plate below... COLD, not cool, COLD

TEST #4
Set to Climate Control to MANUAL... ClimateLine Engaged and set temp to 86 deg; Set Humidity to OFF; and turn on Flow for S9...
1. run 10 minutes at pressure with dry resistance at end of the tube
2. feel heated ClimateLine... no warmth to touch.
3. Stop S9, lift tank out and feel heater plate below... COLD, not cool, COLD

TEST #5
Set to Climate Control to MANUAL... ClimateLine Engaged and set temp to 86 deg; Set Humidity to 0.5; and turn on Flow for S9...
1. run 10 minutes at pressure with dry resistance at end of the tube
2. feel heated ClimateLine... no warmth to touch.
3. Stop S9, lift tank out and feel heater plate below... COLD, not cool, COLD

TEST #6
Set to Climate Control to MANUAL... ClimateLine Engaged and set temp to 86 deg; Set Humidity to 6.0; and turn on Flow for S9...
1. run 10 minutes at pressure with dry resistance at end of the tube
2. feel heated ClimateLine... no warmth to touch.
3. Stop S9, lift tank out and feel heater plate below... COLD, not cool, COLD

TEST #7
Set Warm-up to ON for 3 minutes and Temp to 86 deg
1. run 5 minutes
2. feel heated ClimateLine... warm to touch.
3. Stop S9, lift tank out and feel heater plate below... HOT, not warm, HOT

Any thoughts... have you checked yours ???

Mines been working fine. I did wake one morning to find a dry throat but I had been mouth breathing (which doesn't happen that often). I usually fill my H5i reservoir up to not the Max line but the line under this. I sometimes pre-heat (if I have time) or if not, just let it heat up whilst I'm using it. The air I can tell has more humidity in it than regular air, and it's warm'ish. I only set my temperature at 23C and to Auto, oj the average night the room temperature is getting down to about 12C (quite warm for the UK this time of year).

I'm also seeing some very minute amounts of rainout on some nights, so mine is definitely working. I don't connect/disconnect the H5i often though, about once per week if I travel or once every two weeks if I don't.

Thanks
Dave

I haven't felt my H5i baseplate to see if it's warm, but now I will just to make sure.

I fill the tank to max, go through half a tank a night based on 6 to 8 hours at avg 6 cmH2O, 27C/80F auto climate. House is usually at about 21C and we have a central humidifier so the ambient air is not dry.

My baseplate is warm when I empty the chamber in the morning (provided I do so before too long on the cooldown cycle). It doesn't use a lot of water, but I think that's expected with my temperature set at 75F. It uses from about the first line on the yellow tag down to just about the level of the bottom of the tag for 8 hours of sleep. So, I think my H5i is working fine.

One thought, Nord... you said you've replaced both the H5i and the S9 itself... have you also replaced the ClimateLine hose? I wonder if it is giving the unit bad readings that is causing the humidifier to not turn on?

We have central humidifier at home as well, temperature set at 20c at night.

H5i use very little water, half way between markers each night. The only way to have the plate warm up is pre-head it. Plate always, always cold.

I have been using the slimline host only.

That does not sound too good Nord.

I will check my humidifier plate tonight and tomorrow morning. I never notice the plate temperature before as I always top off my water at night when needed and i never remove the tank to fill it

My room is about 78 degrees and i have the climate set to AUTO and the hose temp to 78. The humidifier chamber has a yellow fill indicator with 3 levels marked with a black stripe. I use a whole level and maybe a bit more each night. So i sleep two nights on a full fill and then i have the refill it again as i don't want to push it to three nights and risk running it dry. So i would say mine appears to be working.

I'm expecting things to change soon as the heat goes up to 110+ degrees for the Arizona summer. My air conditioning will be running, the room will be cooler and the air much dryer so I'm expecting to use more water, only then will I be happy that its fully working and auto adjusting to changes.

I also use a hose cover.

But i would imagine that if it's not coming on in manual mode either then its not likely the climateLine hose?

I may be wrong but Its my thinking that manual mode uses the manual settings 0 - 6, a heated hose temperature but not use the climateLine sensor.

But i may be wrong

Hi Dave

If you see any rainout... then the heater is likely working...
I thought it was using very little water but because dryness has not been much of a problem recently... I crossed it off to that. When it woke me up with dry throat mid-night (no mouth leak) I decided to take a closer look. A couple of days later when I thought it was worse again... I did some tests that, I believe, remove any doubt.

ResMed is replacing the Unit S9 and H5i again in a couple of days.

Hi alterego...

If you're going through a half a tank per night... I would say that it is working properly. I think I just ran into some poor luck as I took an early sample from the ResMed sales rep.

BTW: I have another SD card that I will email you. It is for 2 days but 20 mask events (I had lots of time) and there are 3 separate instances of missing data for 1 minute. And an interesting odd posting of Flow Data that seems to be out of place.

The ClimateLine gets warm on the Warm-up cycle so I think its working when the S9 gives it the signal. It seems that yours is using a reasonable amount of water for 75 deg...

The air is so cold coming out of the mask ports that it wakes me up.

I know you are only using SlimLine right now... but I wouldn't let it go for a long time. Do some tests at several humidity levels and have it run for a while and not too much air blowing across the water cooling off the plate. Take your results to your DME and have them give some answers.

To let you know... My DME contacted ResMed sales rep who said replace and he'll have tech support go over the machine. He also said there is no recall or problem that he is aware of (I think Toyota said that to recently).

Thanks

That doesn't preclude a bad sensor on the hose... the heating element may be fine, but the temp and humidity sensor could be broken.

I think manual mode still has you set the temperature, though right? I don't know how that would be used, but presumably it is still doing something with the temp sensor on the hose. I could be wrong too, it's just a theory of something to check.

Hi Bob

If you have the H5i and room at same temp 78... I wouldn't guess you would even notice yet. You should notice when its 110 deg. even with a/c. It'll be interesting to see how it acts.
Did you get rainout before with the H4i ???

I think you are probably right about the way that ClimateLine works... I guess the sensor could still be an issue but I'm guessing because as you say... it warms up on pre-heat but not in manual mode. I'll soon know.
