I have the following issue:
We live in a single-family house with 170 sqm (1830 sq ft) of living space plus a 55 sqm (590 sq ft) basement. The whole house is ventilated with a Wolf CWL 400 ventilation system.
Currently, there are three of us living in the house. My wife works Monday to Thursday until 3 PM, and after that, our child also comes home.
This means that from Monday to Thursday between 3 PM and 7 AM, 2-3 people are present, on Fridays two people are present all day, and on weekends, three people.
In the mornings, we additionally ventilate the sleeping area and bathroom manually. Cooking fumes are extracted outside via the range hood. There are no particular odor sources.
The system is set to circulate 125 cubic meters per hour (about 74 cubic feet per minute) at night and 230 cubic meters per hour (135 cubic feet per minute) during the day.
It should be noted that the sleeping area has a relatively large volume due to an open attic space. Nevertheless, the air feels stale in the morning.
At night, the ventilation system cannot be set to a higher level because the noise level would then be disturbing.
During daytime operation, the ventilation is audible but not particularly disruptive. However, it is quite loud, especially in the kitchen. This surprises me because the system can deliver up to 400 cubic meters per hour (235 cubic feet per minute), although that would be very loud and disturbing.
My question now is: Is the system set too low at night? Too high during the day? Is the noise level at this "low" setting normal? I have the impression that the exhaust air valves are particularly noticeable in terms of sound, while the supply air is relatively quiet.

you need to ask this question to the person who sold and installed this system for you.He is asking for experiences, which he can get here. As others say, measure the CO2 level and then add dampers, at least in the bedrooms if the values are not acceptable.
