Question about everyday life with a controlled residential ventilation system

You present it as if this causes wear and tear damage.

What about intensive ventilation? What about sensors that can control the systems? Weekly programs? All contrary to the characteristic curves...

Wear always occurs - but I very much doubt right now that you have a reliable study to support the assumption showing how much a system suffers from it.

What about intensive ventilation? What about sensors that can control the systems? Weekly schedules? All contrary to the characteristic curves...

On the contrary, precisely the sensors, weekly schedules, etc. allow the systems to operate within the specified parameters.

But it doesn't matter...
That leads to nothing.

If you think so, then so be it. However, that does not change the way the system works.

but simply determined the pressure differences through the power consumption of the fans.

Will that change because of an open window? Nothing changes at the air outlet in the bedroom, the next extraction (bathroom?) might draw in leakage air through the open window. The pressure drop across the filter in the intake duct directly affects the fan, yes. But an open window should hardly affect the pressure at the supply air outlet or exhaust fan. Am I missing something?

Working within the given parameters? Sounds great, but it simply says nothing...

If the system runs at full power for 10 minutes when pressing a button (and that several times a day), what is better about that than an open window overnight with the supposedly strong impact on the very sensitive system setting? Don’t talk about given parameters – normally you can adjust EVERYTHING in the settings, no automation supervises anything.

As long as you don’t have individual volume flow control, a system balancing is never 100% accurate – most companies just go through the place once, attach an anemometer, and that’s it...

How does it actually work when integrating a heat pump that cools in summer? Is an evaporator then built into the ventilation to cool the house? Per FB water circuit probably doesn't help much except cold feet.

Do you have CO2 and humidity sensors in every room? So that the airflow is automatically increased when bathing or when 15 people are visiting, or reduced when the house is empty?

Per FB water cycle probably won't do much except cold feet.

But that's exactly how it works. Cooling via controlled residential ventilation brings nothing because the air exchange rate is too low.

Do you have CO2 and humidity sensors in every room? So that the airflow is automatically increased when you shower or have 15 people visiting, or switched off when the house is empty?

I refrained from that because it's expensive – normally you don't do that in every room, only where such events are expected.

I can adjust the ventilation higher via web interface if necessary and have a push button in every bathroom that boosts the ventilation for a certain time. I consider that sufficient...
