ᐅ Question about daily living with a mechanical ventilation system with heat recovery

Hello, my question is aimed at those who already live in a well-insulated house with a controlled ventilation system: How does it work in winter after a long hot shower? In my case (an apartment from the 2000s), the bathroom becomes foggy, the tiles are all wet, etc., meaning I have to ventilate thoroughly.
Is there a "boost" function to remove the moisture from the bathroom? Or do you have to open the window the traditional way?
How is it in summer when you want to sleep with the window open?
Can you turn off the ventilation completely during the night?
Or, if you are not at home during the day, can you reduce or pause the ventilation?

Leave the planning, buy the parts, connect them, plug it in, next build.But that is a flaw. The systems need to be measured, and if the heating technician didn’t do this, they have to correct it. Unless you only bought one controlled residential ventilation unit without anything else.
That may be true. But I have to live with it. I will probably be able to live with it better if I did it myself.
Already done. The problem is not that the system is running outside the specifications. My problem is that the shortest pipes with the lowest backpressure get too much volume flow. Since the Vaillant system specifications only include throttles via the valve (which is not sufficient), nothing can be done.
The Zehnder throttles I purchased do not "officially" fit my Vaillant system. 🙄

In the other apartment the system was also set too high. There is a maintenance menu where the airflow can be restricted via software.

You can use slide-in dampers for this.
To measure it properly, you need an anemometer with the right specifications and measurement capabilities. I once made something from a PVC pipe T-joint and rubber bands.
Having the proper measuring tool, possibly borrowed from somewhere, is of course more convenient.

That’s exactly what I was getting at. Thanks! There’s a site where you can rent it for 27€ per day. I’ll look into that. Maybe a neighbor will even pitch in a case of beer for balancing several houses over the weekend.
So, you’ve done this before and it’s not rocket science? The throttles are here. For now, I’ll probably have my wife go from valve to valve at the manifold to figure out where everything is routed. Of course, nothing is labeled.
