All S9 users - Is H5i working ??

[Nord]

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.

I think its a reasonable theory to check... but I won't know for sure because I won't be able to substitute 1 thing at a time to test. They are going to replace it all and test. Hopefully they will give me some feedback... but I won't hold my breath cause that would be an "unearned Apnea"

Thanks

The main reason I got the S9 was then Climate Control since the humidity varies greatly at different times of the year and I seem to require a high humidity level. I started using Auto but would still have a dry throat, not from mouth breathing. I tried raising the temp to get more humidity to no avail. Maybe I need more than 80% humidity? Water usage has been from a quarter to three quarter tank, Humidifier working? Changed to manual, at 5.5 got some moisture in vent air, temp was 80. Last night, started at 4.5 temp 80, after three hours, hose cool and tank cool. Raised temp to 86 and humid to 5, after three hours, hose cool and tank very warm. During the two hours I tried to go back to sleep, I detected a change in temperature and smell for about 10 seconds. The vent air actually got warm. Shut machine off to check tank temp, warm and hose slightly warm. Could this be software related? My machine has version SX474-0601.

When CPAP.com opens I will be calling them to talk about the problem. They will probably want to replace part or all of equipment. In any event, will post results of our attempts to get to the bottom of the problem.

Hi Steve

I don't think its a firmware problem... as far as I know everyone so far has the same firmware.
I do believe its either a printed board issue or connection. An RT on here suggested that H3i's and H4i's had intermittent problems that was related to loose connections inside. I'm guessing that took place over some use/ time ???
This occurs to only some and may be an assembly issue or a maintenance issue.

I'm sure that some think that my expectations are too high... but my humidity and heat are non-existent compared to the Respironics M Series... of course rainout was a constant threat.

Have you tried cleaning connections at the hose to H5i and H5i to S9 ???
My S9/ H5i is being replaced on Saturday and tech support will be getting some answers.
I'll keep you posted when/ if they report back to me.
Let me know what you find out at your end.

Thanks
Nord

CPAP.COM suggested that I try the slimline hose to see if the humidity problem continues. I will try that tonight because I said i would, then I will try cleaning connections. If they have had connection problems in the past, that could explain the problem. I suspect a communication problem between the S9 and the H5i.

Hi Steve...

I did use the SlimLine for the first week... ClimateLine was backordered.

For me... it was still the heating problem. It still did not put enough humidity into the air except the blower was certainly picking up some cold water. Again, my pre-heater was working just fine. I suspect either the controller board or connection.

More likely as you suggest... connections. I'm going to take a closer look at it later tonight.

I'll let you know,
Nord

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.

Just to follow up i did check my heated plate in the H5i humidifier last night. I pre heated it for about 30 seconds then popped the lid and removed the tank and the plate was very hot.
Also yesterday was a very warm day and my house was 85 degrees and warmer than that in some rooms. So we turned out air conditioning on last night which is set to 72. I left the machine set to 78 for the hose temp and in the morning i found that the water level had gone down two level lines from being full. That must be about half a tank.

I have never had rain out with the H5i but i used to have rainout often with the H4i even with a heated repti-cable run between the hose and the hose cover, I could never have my H4i dial setting above 2.

I hope you get yours fixed soon.

I thought about the firmware issue this morning, but looks like everyone is using SX474-0601 version.

I pre-heat the tank last night, the heating pad became quite warm, however in the morning, back to room temperature again. Water down 1 level, previously only 1/2 level, must due to the pre-heat.

I picked up my S9 last Tuesday and checked the H5i last night after reading this topic. As far as I can see it doesn't work. The plate and hose never warm up no matter what setting I have the climate control on. I've logged a warranty issue with the supplier. Classy piece of Resmed quality manufacturing. Not working out of the box. I'd have to say I'm rather pissed off.

If I set mine to Auto and set the temperature to 23C and pre-warm for several minutes, check the hot plate mine warms up nicely.

Have you tried cleaning the contacts on the hose/machine? Some people have found bits of plastic covering parts of the contacts. Maybe give it a wiggle too.

If not, hope you get it replaced under warranty. Mine's been working flawlessly since February, so hope you get yours sorted soon

Thanks
Dave

No known problems here. I think I'll start with test 7.

The only time the hot plate warms up is when I run the prewarm function but when it moves into normal operation the plate cools down to room temperature and I have felt no change in temeprature at all with the hose.

Typing between nodding off -- First night with my shiny new S9 and spent the night adding blankets until it dawned on me to check the H5i -- warmup had worked fine, but plate and water ice cold in the morning-- have the ClimateLine but used Slimline first -- so thanks, Nord, and others for the info --

[dave21]

Gadget_OSA , GardenFan, here's my take on why the pre-heat heats but if you check the plate in the morning it's not hot.

If you're using the H5i with ClimateLine hose, the object is to keep the temperature of the oxygen at the same level (it's measured coming out of the H5i and down the tube and re-measured at the mask.

To start with, at night you've put most likely cold water into the H5i reservoir, so either with a pre-heat or without a pre-heat, the plate needs to heat up to get it to optimum temperature to heat the oxygen so that if you set the temperature at say 28C that the air is 28C when it's delivered to the mask.

It will ensure that the temperature at the mask is retained throughout the night. It will switch the plate off if the optimum temperature is reached or at least reduce the heat when it's not needed.

Most people tend to switch their central heating off in the house over night, because you're sleeping and there isn't a need for continuous sleep, so if the house temperature drops because of this (or because the temperature outside the house drops) that means the temperature of the Oxygen will drop coming through your mask, when this is noticed the H5i will heat the plate to ensure the oxygen is heated to your setting and re-heat the water.

In the early hours of the morning is where it's coldest, e.g. midnight to 2am, temperatures usually start to gradually warm from around 4am onwards. If the oxygen coming through to the mask is at it's optimum temperature, e.g. because the house is warming up then again the plate will shut itself off.

I think what you are expecting is the plate will be hot all the time? That shouldn't be the case, think that it has a thermostat like your house or perhaps your car. When it reaches optimum temperature it will switch the plate off, when the temperature drops, it'll switch it back on again (or change the intensity of the heat).

1) If pre-heat is working in theory there shouldn't be any reason why regular heating would work. If you don't think it's working, try running with your mask on for an hour whilst sitting whilst watching TV and then check the hot plate

2) If you have the SlimLine hose and not the ClimageLine hose, all you're going to get is a humidity change.

Thanks

All sane and reasonable Dave and that's how I would expect it to work however the only time my H5i plate warms up is when I run the preheat function and as soon as that is finished it drops back to room temp. I have not seen the plate warm up at any other time and I've tried Auto / Manual / Patient settings with various temperature and humdity settings.

Have you tried to rise the humidity and test it out.

I have wrote on another thread:

Last night I set the humidifier to the max (6), woke up around 5:30 am and heard strange wesing sound (like it is in a turbo mode) from the machine. Was I woke up by that noise?! don't know. I open the water chamber and feel the heating pad IS warm. I then turned the humidity down to 4, the strange sound eventually faded away about half hour later. In the morning I took off the nasal pillow, water splash out and the hose got rain out. The water level down about 1-1/2 level from the normal 1/2.

Looks like the H5i does response to the setting change. I'll try the setting to 5 tonight and see what is the outcome.

Does the machine sounds warning/alarm when in the risk of rain out? Wondering why the strange noise, was it trying to cold down?
