[*]Hello everyone,
is there actually a regulation about the times when a controlled residential ventilation system is allowed to run and when not, or on which levels it is allowed to run?
We currently have quite a bit of stress with one of our neighbors who totally loses it as soon as the system runs on level 3 or level 4. According to the manufacturer, level 1 is only to be used during absence (e.g. vacation), levels 2-3 are normal operation (we normally only use level 2), level 4 is for things like visits, drying laundry, cooking, showering, bathing, etc.
In summer, we run the system in the late afternoon or early evening (depending) on level 3 to ventilate the relatively cooler outside air from the east side (where the intake is located) into the rooms on the upper floor (children’s rooms) because otherwise it is boiling hot there and the kids are in bed early, which means the windows can’t be opened (on the one hand because of the risk that the child might climb out the window but also because it would simply be too bright in the room, not to mention the evening sun shining on the laminate floor, heating it up and the floor then giving off heat back into the room overnight). This regularly leads to angry remarks from the neighbor. I work in a facility for people with disabilities and, for example, my neighbor has already asked me whether I work there or am being cared for and said my poor child can’t choose their parents, etc.
Anyway, the installer of the whole system has already been on site and said everything was okay (it really could have been that something was wrong with the system).
Now the question is, which nobody has been able to answer me so far: Is there generally a regulation specifically for such systems (similar to operating a lawn mower etc. until 8 p.m.) stating that certain values must not be exceeded at certain times, or does only the general noise protection ordinance or whatever it is called apply? Maybe someone knows more about this, I only know someone who works at the environmental agency who says it is generally a growing issue (also in relation to air heat pumps).
The house was built in 2013, the system is a Vallox 090sc, the device is located in the attic on the inside of the east gable wall, the air intake and outlet are accordingly on the outside of the gable wall with a combined air hood (a wide slot for one and a large opening downwards for the other, I don’t know which is intake and which is outlet).
And yes, I know it’s not air conditioning, but the benefit in summer is clearly the cooler outside air and level 3 is still “normal” operation according to the manufacturer, we have only used level 4 when we had visitors in winter, but I don’t know how big the difference between 3 and 4 is.
Oh yes, the location is Schleswig-Holstein.
Kind regards
