ᐅ Enthalpy Heat Exchanger for Central Controlled Residential Ventilation

Hello everyone,
We have a central mechanical ventilation system from Tecalor (THZ 180/280) with, according to our heating technician, an enthalpy heat exchanger installed.
In winter, we now notice that the indoor humidity in the living area averages around 40%, which is relatively low—but not uncommon during winter.
Nevertheless, we specifically had an enthalpy heat exchanger installed to prevent this. My question is: How can I tell if the enthalpy heat exchanger is actually installed?
In my operating manual, there is a guide for replacing the “heat exchanger.” Is this usually an enthalpy heat exchanger, or can it also be a “standard” heat exchanger? How can I distinguish between the two?
I just want to be sure whether it has actually been installed (I have a few slight doubts due to past experiences with my heating technician 😀).
And now the question: Is this level of indoor humidity in winter normal despite having a mechanical ventilation system with an enthalpy heat exchanger, or should the humidity be significantly higher under these conditions?

I’m not familiar with the system used, but to me it sounds incorrect. When the bypass is active, the airflow is not directed through the heat exchanger, but around it (to prevent the exhaust air from warming the supply air). This effectively turns the heat exchanger off. It doesn’t seem to be a sensible approach 🙂

When the bypass is active, the airflow doesn’t go through the heat exchanger but around it (to prevent the exhaust air from warming the incoming fresh air). This essentially switches off the heat exchanger. That doesn’t seem effective to me 🙂I agree completely... Tecalor TVZ 180.
