Hello everyone,
to all controlled residential ventilation system owners: Have you ever measured the CO₂ levels in ppm in your ventilated rooms out of curiosity?
According to information online, the values should be below 1000 ppm. About 400 ppm is the fresh outdoor air level. Normally, I have around 600 ppm – 700 ppm when no one is in the room. Of course, this value increases with the number of people present.
What I’ve noticed is that in our bedroom, the level rises above 1000 ppm during the night, which is not ideal. I originally thought that was exactly why I installed a controlled residential ventilation system – to always have fresh air.
So, I would be interested in comparison values from you, if you have any.
Maybe something is wrong with the system.

Okay, but that means the hallways must also be included since they serve as overflow areas, even if there are no supply or exhaust vents there. What about a connecting room (airlock) between the living area and the garage—would that also be counted as an overflow area, or is it excluded?
