Question about everyday life with a controlled residential ventilation system

Leave the planning, buy parts, connect, plug in, next construction.

But that is a defect. The systems must be calibrated, and if the heating technician didn’t do that, he has to fix it. Unless you only bought 1 x Controlled Residential Ventilation without anything else.

Could be. But I have to live with it. I will probably live better with it if I did it myself.

In the other apartment, the system was also set too high. There is a maintenance menu where the air volumes can be throttled via software.

Already done. The problem is not that the system is running outside of specifications. My problem is that the shortest pipes with the lowest backpressure receive too much volume flow. Since the system specifications of Vaillant only have the throttles over the valve (which is not sufficient), he can do nothing.

The Zehnder throttles I got officially don’t fit my Vaillant system. :rolleyes:

You can use chokes for insertion.

For calibration, you just need an anemometer with the appropriate properties and measurements. I once made something out of an HT pipe T-piece and rubber bands.

The right tool for calibration, possibly borrowed from somewhere, is of course more comfortable.

That's exactly what I was getting at. Thank you! There is a site where you can rent it for €27 a day. I’ll give that a try. Maybe even a neighbor will contribute a case of beer for adjusting several houses over the weekend.

So you've already done it and it's no rocket science? The throttles are here. I’ll probably have my wife go from valve to valve first to check at the manifold what is connected where. Of course, nothing is labeled.

Take the right one, with it you are simply faster and it is easy for the layman to handle.
