I can only imagine that this is meant to prevent too much moisture in the summer. (ein eher theoretisches Problem, meines Wissens nach) It works fine as it is.
Don't know the system used, but it sounds wrong to me. If the bypass is active, the airflow is not directed through the heat exchanger, but around it (to prevent the exhaust air from heating the supply air). This basically switches off the heat exchanger. Doesn't seem to be effective to me :)

That's exactly how I see it too... Tecalor TVZ 180.
Was that the one who initially didn’t install the enthalpy exchanger at all but rather a normal one? Could it be that he is afraid of the part and therefore initially doesn’t install it and then says it needs to be bypassed?
