Ventilation system CO² [ppm] in your rooms

Yes, it goes like this:



Beforehand, a calculation is made to determine what value/volume flow should be set for which valve.

If it hasn't happened with you, then quickly send a complaint to the installer of the system.

Do you hear your controlled residential ventilation system that extremely as well?

What is extreme for you? At (almost) full capacity, all systems are loud.

Thank you for the picture Well, I don't know if he did it that way with the setting, I wasn't there. Based on my previous experiences, probably not.

Exactly, and that's the point—the system is running at 70% and therefore it is loud. It's also a question whether it might be undersized?

No, it is not too small, it is designed for 0.5 so the 70% fits. How old is it? possibly the pipe diameters are too small. Is a silencer present?

is pre-run. half a year old. I find it loud, you can hear it like a loud blower in the basement utility room. Even when I close the door of the utility room, I can still hear it quietly in the ground floor hallway. It is also loud like a blower where the system blows out the air. Noise dampers are installed, but the system itself makes the noise. Well, I guess I'll have to have someone from Vallox come by, but that just costs again.

Hmm is also just a blower... you can also hear the ventilation in the car... it's nothing else

I have another question. Is the total volume of all rooms now included in the calculation of the [Kontrollierte-Wohnraumlüftung], including rooms that do not have supply or exhaust vents, such as our hallways or the airlock to the garage, or are only the rooms with installed vents counted?! That would make a huge difference.
