Thank you so much for this! I have this exact model. I didn't know how to adjust anything, and was stuck with the settings the installer put in, since this video, I have changed the settings to suit our house, after 3 years living with this model, and having to manually boost all the time. Now I've set it to quiet mode in the evening and night, I can sleep in silence! I've looked everywhere on the internet for manuals, all useless, until this!
Glad I could help!
This unit brings toxic air inside my apartment I live in a new building and I started having rapid heart rate, palpitations and tremors at night because the smell it delivery to inside my apartment. Is there anyway someone installed it wrong or some wrong tive was attached to my vent to give nasty air inside my apartment?
@@xxxx-wv6hphave you got the outside intake near a boiler flue? If it’s sucking that in then it is very dangerous and you should turn it off.
very helpful way more use than the manual that came with the machine !!
Yeah the more in depth manuals such a the commissioning manuals are usually on the site where it's bought from in PDF format
Super helpful guide, navigating through the manual was hard. This video was concise, covered everything in the manual
Great video! We have just moved to a new flat and we had no idea on how to set this up!!!
Thanks mate
You have made my day with this video sir. I didn't find the way into this menu anymore. I did find it once though, but I couldn't remember how to get in, lol.
This helped me set up my own, thanks
The boost airflow automatically turns itself on stating boost airflow 47%. How can I turn this off ? I’m concerned about the electricity it consumes while being in that mode. Also, any rough idea how much electricity it actually consumes ?
I'm having the same prob. Were you able to figure out how to turn it off? Thanks
Very helpful, thank you for posting it 👍👍
I have this in my flat. Still have no idea what it does or how to work it
We have an identical machine. Probably the same. We are setting it up. But it's stuck on 2 menus. The time and normal air flow screens. You can manually boost it as well. That's it. Cannot get the other options you have here.
Hi, sorry I'm being a bit thick. During the winter season, what temperatures do I need to set to guarantee enough warmth in the apartment? Would Indoor = 20° and outdoor= 20° work? Thanks
I'm new to this and the current temperature is 16° everywhere even with the heating turned on.
Set it to 25 inside and 10 outside
Winter only
I’m so dumb I still don’t understand, if I want to cool my house what do I do?
It’s 30c outside right now, my inside temp is set at 16c (lowest it can go) and my outside temp is set at 20 (highest it can go) and then summer mode is set to ON
Thanks for the video, how would I ensure maximum coolness during the summer? Please kindly confirm the settings required, I would really appreciate this advice! Thanks 😊
It gets very very hot in the evenings!
So helpful! Thank you
I put mine in diagnostic mode and can’t get it out, any help?
Mine is constantly on Control mode Fan off, does anyone know how to fix that or turn it back on?
Thank you so so much!!
I agree with Chris, the manual that comes with the machine is not helpful at all. I have a feeling reason being is to someone to get service fees however - i think you don't need to change settings much after it is installed. Thanks for the video anyway - I need to figure out the password for mine.
How to turn off this? Bcz I'm facing a noise issue in my apartment.
Hi this vent is making me sick the air it brings inside smells like chemicals it is screwing our health. Is there any option to only push bad air from inside to outside instead of getting air from outside in? Please let me know asap
there is no normal airflow on mine is there a setting for that
Hi I've just moved into a new place and it has a sentinel multivent A. It's black with an lcd screen in the top right corner with 3 buttons. There's no instructions on how to set it anywhere. I've looked on the internet with no luck. You wouldn't happen to know how to program it so the low normal and boost settings can be changed to different times? Thanks in advance.
Wasn't clear on the humidity bit.
If the air in your home is quite dry and uncomfortable, what percentage should you put it to?
Relative Humidity is relative to temperatue .
Specific humidity of 7-8 grammes per Kilogramme of air which is pretty much 1 Cubic metre of Air, this is optimum.
@richardmarlow4466 but I mean, what settings should I be aiming for to reduce the uncomfortable dryness of the air? There's a similar comment/request on here already but I don't understand the answer.
Causing dry throat/skin and just general feeling of discomfort in the flat. Great for quick drying clothes, but horrible for a good night's sleep.
why is the boots airflow mode still on?
hi! great so see this, the manual does not mention these things that well.
my very similar system from vent axia has been installed but i ve noticed that all percentages are equal for extract and supply. does that mean no balancing has been done by the company that installed it (i bought the flat finished and new)? can i fix these things myself ? its a simple one bedroom flat with 2 supply outlets and 3 (i guess, toilet bathroom and kitchen) extract points.
furthermore, i ve noticed it sometimes goes into boost at night, presumable ddue to paramters, which is noisy for me. so via the way you explained i have decreased boost extract and supply to 50, normal to 30 and low airflow (timed for sleeping hours) to 15. is that allright?
I lost 6Kw during my sleep, I am wondering is this from ventaxia or fridge-freezer?
This fan does not pull that much current, may be a heater somewhere, unless there is frost protection heater as well.
anyone knows this? 70% humidity seems higher than recommended, despite it being the default level. the machine can not be st lowre than 60% i noticed. while 40 to 60% is recommended according to some websites ( i am not an expert! might be wrong figures!).
what do you think about this all? how to fix it ?
In the summertime, if the unit is able to be set at lower humidity like 50% it would run in perpetual boost and keep you awake all night, especially if the boost rate is set high. unfortunately, this particular model cant set profiles for one scenario and another. It's one setting for all seasons which is a shame. Wintertime you could set it to 60% RH and it would regulate that on normal mode and behave fine. we only have the outdoor air to reduce vapour pressure and the specific humidity. some systems have chillers so its possible to set lower RH levels. I agree,the Goldilocks zone to keep all things nice is between 50% and 60%.RH With this unit its best to set 70% for summertime if you want a good kip.
After 10 years of no issues, my vent axia has started to make a lot of noise. We had it serviced 2 months ago and filters changed, but no improvement. How can we get rid of this noise?
check the atmosphere terminals are not clogged up and check if any debris is fouling the impellers.
I have exactly same moulde now its stuck fan not working on the screen shows CONTROL MODE FAN OFF
Hi Richard.
Well explained and informative.
though' Is it possible for you to "spell out" How to do if our house is at and constant 28% humidity.
Its especially during evening/night where we can feel it - waking up with dry throats and dry skin. We just moved in and live in a very well insulated new house, so the machine is quite new to us.
Thanks, Chris
it seems to that your unit is over ventilating and needs the flow rate reducing in the evening. call me on 07985174736 i should be able to talk you through the changes required on the module. internal humidity is always relative to atmospheric temperature/humidity and occupancy. You have little moisture creating activity at night therefore the RH humidity will drop
@@richardmarlow4466 Thanks Richard. Since I wrote my message, I have actually done what you mention. It seems like you where spot on. Today we have a humidity at 41%.
When Its winter time - would it be a good idea to have it run at the slower flow rate all the time?
Thanks again, Chris
@@FordChristmas drive.google.com/file/d/1b88JxmrkewbsUkoLOCjkF8BS3FSiYghc/view?usp=sharing check this out around 45% is considered the goldilocks zone and what we should be aiming for, between 30 and 60% is the target for optimum health benefits.
have you initiated control mode 2 to manually select the low mode?
there is a balance between optimum air quality and acoustics that can mean setting the humidity setting higher as in the height of summer and hot sticky nights the init could run in boost throughout the night. choose a sensible humidity that gives you this balance. don't lower the flow rate in the daytime during summer, winter daytime possibly if low occupancy, you wouldn't want to forfeit optimum oxygen levels.
Question to anyone who has one. I got mine instaled yesterday. Do all of them make a noise in the rooms? The 40 precent its minimum and i feel like its bit strong
I've just moved into a flat and the system consistently remains on Boost Airflow 70%, despite me changing the normal mode hours from 7am to 10pm. Any ideas how I can get it to move to normal or even low mode to reduce the noise & electricity used?
Hey! I'm stuck on boost as well!! Did you figure out how to get it to normal? Cheers
@Irishrover11 It turns out our unit is configured to go on boost for 12 minutes whenever a bathroom light has been switched on, so in a larger household it always seems to be boosting for us
Useful video.What does defrost mode do. I can't get it off that atm
it will tun off the supply fan or the MVHR until it thinks the heat exchanger is safe, dont mess with this.
My machine seems to be stuck on boost mode 50% and won’t change to normal airflow? Set the overrun to 5 mins like you suggested but still stuck!
Initiating boost by clicking the home snowflake button only gives me the option to run a boost 1s. Then after that it’s finished, it returns to boost 50%? Any tips!
I have the same problem. In my case it’s on 65%. Did you manage to sort it?
the switch live cable could be wired to the live cable st the spur, also the humidity setting is too low
How can i see the extract temperature and the provide temperature? Does it have such sensors?
Thanks for the video @richard. Any advice on a unit that stays in boost for hrs after the humidity sensors gets set off? It has been working all winter fine since it’s install new. Thanks
What is your humidity set point and overun settings?
In the bathroom, there is condensation for a number of hours after a shower, how do I address this with the HRV? The humidity is set at 65%. Any help would be appreciated
Lower the humidity to 55% and increase the boost rate by 10%
You could also initiate purge mode.
Yep, usefull, thx !
Got a rattling sound with the extraction fan, do you know if it's easy to access and clean? I've removed the the heat exchange and I can see the supply fan, but not the other one
How to unlock this ? I put 3 digit password and I don't have access now to main menu
Hello, how do you do to modify for example all the day at 15% low flow rate ?
For the moment the normal flow rate is 30%.
This is not well explained in the manual mode.
Thanks
you need to set up control mode 2
Hi, I have one of these in my home and it the airflow is set at 80% aswell as the filter is this the correct setting because I don’t seem to be getting much air coming through my bathroom
Depending on installer, a bathroom would normally be set to extract (to pull out excessively humid air). So you shouldn't feel air coming from the bathroom ceiling vent, but leaving the room that way. Air fed into the other rooms (bedrooms, lounge, etc) should be flowing through the corridors and under the closed doors to get to the extraction point(s) (typically bathroom, kitchen, and hallways near external doors).
Hi Richard. If I was in a hotel room and I wanted to turn the fan noise off, which setting on the control panel could I use? Hypothetically speaking
Initiate control mode 2 which means installing a link across SW5
Then set your low fan speeds to 15%.
This will give you manual control of the low user setting.
Its important the machine isnt turned off.
@richardmarlow4466 what settings would you recommend for cold winter temps ? From say 0 degrees to 8 ? Should indoor temp be mid 20’s ? And outdoor be quite low setting? And also what would normal supply and low supply be ? Thanks so much , have been trying to find out from manuals for so long
for winter set mvhr to 25 degress indoor, 10 degrees outdoor
@@richardmarlow4466thanks so much , appreciate you getting back to me !
Would this unit help reduce temperatures during the summer? What temperature should i set it to?
same question
No, you have a summer mode but its runs very high and does not work 🤷🏻♂️
how do you turn the vent off?
It looks like there is a small gap above the control panel. Ours seems to have this too since the engineers refitted the front panel. Is this normal with this unit?
I have the exact same, looks normal
Its normal. The air seals are higher up.
The unit installed in our property has stopped working with message on screen “ Control Mode Fan Off”
We cant change the settings, when pressing the buttons on the controller nothing changes ! Tried everything turning off and back on. Any suggestions ?
Hello Richard, we've got vent axia but I dont know how to turn it off via display. Only by turning off the circuit breaker. Thank u for answer.
An MVHR isnt supposed to be turned off, if it does remain off for a period of time condensation will form in the ductwork wherever dew point is reached, what can happen then is mould spores will form and begin to propagate. then when you come to turn it back on these spores would be blown into the property and become airbourne. if you go on holiday or are sleeping, you could set the low mode to 25% fan speed and set as schedule. there is another control mode aswell check the manual regarding control mode 2 it allows manual selection of low mode.
also if left off it will vent passivly to atmosphere which will produce no thermodynamic transfer and will result in massive heat loss.
dont turn it off!
@@richardmarlow4466 thank you for this information
My fire department sent a note to turn ventilation of. Because of a fire so ?🤷🏻♂️
How do you open the machine to clean the filters?
sometimes the filter access flaps can be stubborn to open, use a butter knife and gently prise them open.
Hi! Maybe someone can help me here. My ventaxia unit is always on boost mode and I can’t change it normal mode.
Hello, Have you found the fix to this? I have the same issue. Thanks
lamine boumdian I have not I’m afraid. I dropped the boost to 50% so it’s a bit quieter. I believe there’s a switch somewhere in the house that is keeping it on but I can’t find where.
on my case it was after a all a switch in the kitchen that I never understood what it was for lol... keep trying by playing with switches in the kitchen and bathroom. Also, you might have some wrong setting regarding humidity/temperature in the controler. good luck!
lamine boumdian oh yeah? I will have a look at those settings then. Thanks! Also, never tried the kitchen to be fair. Was the switch in kitchen labelled at all or was it just a random switch?
@@microcuts01 yes nice label "Fan Boost" lol.... but I had two in bathrooms without label
Does summer mode kick in automatically?
I believe you have to choose it When mine was installed the Tech said that in England you would hardly ever need it.
@@Chris-gj6ef I don't even see a button to change it but I can see the option on the console. British weather is horrendously humid, I have definitely needed it! And more so due to climate change over the coming years
How well do these things actually cool during the summer?
Cooling is dependent on the buildings insulation, airtightness result and G value of glazing.
Consider a thermos flask it keeps thinks cool as well as hot. Your house if well insulated will retain the free cooling that is brought into the house during the evening.
Irradiance needs to be mitigated by installing low G value fenestration.
Also air velocity dehumidifies to help with comfort.
Thanks
