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?

Google says "HRV" is a standard counterflow heat exchanger. The enthalpy version is called "CRV".
You can find it from the manufacturer "Core Life". I just spoke with the company Tecalor – they confirmed this to me as well.
I am extremely upset, especially since it was part of our contract and was confirmed to me several times... 🙁
The price difference is not just a few euros either...

I am currently drafting an email to the heating installer and general contractor.
In general, an enthalpy heat exchanger does not create humidity; it simply reduces the amount of air being exhausted or returns it to the supply air.
A family of four or five that does a lot of laundry, showering, bathing, cooking, etc., will have different values compared to a couple household with two full-time working adults.
