Central ventilation system - is moisture recovery necessary?

You just have to (like with the heating) familiarize yourself a bit with your device and experiment. I can set the fan speed for 3 levels in percentage as I like. Accordingly, I have set the "low" and "medium" levels lower and programmed it over a time schedule throughout the day. Currently, we have an air exchange rate of 0.3. That’s more than enough – the 0.5 is not necessarily needed

Can't every system do that? But reducing the air exchange rate and then saying that the rooms don’t dry out is exactly what we basically say. But hey, another tip, just turn it off then you have >50% and can ventilate manually again.

Don't exaggerate so much. He is right. You don't have to overdo it with ventilation either, 0.5 is high. Normal is 0.3. Turning it down is therefore not bad advice.

I just want to point out again that you can switch it when retrofitting. In summer, you might even be able to get moisture out more easily...

Does anyone happen to know where or how best to store the unused WT?

Why do I ask?
We replaced our enthalpy WT with a normal WT because we couldn’t get the humidity out of the house even after 1.5 years.

The removed E-WT is currently in the box in the garage.
Will there be any problems when reinstalling it in maybe 1-2 years if we swap it back?

I simply keep mine in the cold attic. They are low-maintenance from Helios, just rinse them off in the shower, done. I would always have 2 heat exchangers, in May-June humidity can already rise above 70% if you leave the ET heat exchanger in.

In summer, the bypass is on. That means the air bypasses the heat exchanger anyway.

Yes exactly, it is even recommended because then the building drying is finished and then you have the choice in winter with enthalpy and in summer without.

Isn't it more sensible to run via a bypass in summer? Why should one operate through a heat exchanger in summer?
