ᐅ Ventilation with Mechanical Ventilation Systems

Hello Herbert,

Of course, you’re allowed to do that. The system won’t be damaged, but you’ll lose the benefits of the controlled residential ventilation (pollen/dust filtration, possible cooling, insect protection, possible cooling). However, there is basically no reason not to switch off the system during summer (you can also keep it running, but then you’ll just be using electricity unnecessarily) and simply open the windows.

Regards,

Sebastian

That means for short ventilation you don’t need to turn it off, but for longer ventilation you have to turn it off?

Thanks and regards
Herbert

In summer, you can open the windows and then set the ventilation system to minimum. At least, that's what I've heard, to prevent condensation inside the pipes and mold growth. However, you will lose the filtration during summer.

In winter, you should avoid opening the windows because you would be letting energy (heat) escape without recovery. For example, I have a boost ventilation function to use briefly, like when you do some chores, etc. 🙂

Thank you for your contribution. How exactly does the rapid ventilation function work?

This can be implemented in different ways at least with my controlled residential ventilation system:
A push button or via the control unit. A push button in the bathroom, for example while showering, or simply to activate it for other purposes.
As an alternative or in addition, the system could be automatically controlled by a humidity sensor or a CO2 sensor.

You can run the ventilation at full power and open the window! Where’s the problem? It just doesn’t make sense to keep the ventilation running then... but if you’re not technically skilled and can’t manage to lower the HRV, then go ahead and do that! However, it will consume a bit of fan electricity...
