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?

Then, have fun.
In a KFW40+ house or even better without mechanical ventilation with heat recovery.
I can only advise you: get properly informed about this topic before you compare a new build of KFW40+ or better standard with your current old building.
Where your moisture still somehow comes out of your "old shack" today, in the planned building it won’t, or only poorly.
Your window ventilation approach completely contradicts all your ideas about efficiency. Especially in winter and the transitional seasons.
You are an engineer. So a smart man! In another thread here you talk about heat contributions from refrigerators in a passive house and saving a heat pump and heating directly with electricity... and then wanting to ventilate by opening windows. Yes: great. For me, that doesn’t add up. You want to build something that won’t work. At least not in the way you intend.
Well, it is/will be your house. You’ll have to solve the resulting problems without mechanical ventilation later on. I’ll say this — unusually for me — blunt and straightforward.
Best regards
ThorstenYou must have mistaken me. I am not an engineer, nor do I live in an old shack. Also, I’m not building any KFW-whatever nonsense, but a standard 2015 energy-saving regulation house. Efficiency is totally irrelevant to me as well. My house needs to fit a 3-liter bi-turbo diesel polluter.

Not having a good day, apparently.
I got a bit mixed up. I’m very sorry about that.
Thank you for your understanding. *feeling embarrassed* oops:
Best regards,

Just not in the best mood today.
Thank you for your understanding.

ThorstenNo problem. My three emoticons were actually meant to show that I’m feeling very good about it today.

As soon as a window is open, the balance is disturbed and the system tries to compensate by constantly adjusting the fan speed up and down... Is that (always) the case? Why would it be? That would require volume flow or pressure measurements; I somehow doubt that standard mechanical ventilation with heat recovery has this kind of feature.
Just for the sake of completeness: An open window means fully open, not tilted, because we all know that tilted windows only cool the reveal but do not provide effective air exchange. Okay?
