ᐅ Including the basement in a mechanical ventilation system: disadvantages and potential risks?

Hello,
We are planning to install a Zehnder Q350 to ventilate and exhaust our basement as well:
A living area of about 20 m² (215 sq ft) with underfloor heating (supply air), a utility room (extract air), a storage room (extract air). The basement is made of concrete and insulated.
I am aware of the benefits, but I have read and heard different opinions about the disadvantages and risks (condensation, summer humidity, etc.).

1. How is it during the peak summer months and the risk of introducing extreme humidity into the basement? Is a bypass helpful in this case?
2. Does an enthalpy heat exchanger have any disadvantages here?

I would appreciate any long-term experience you can share.

Thank you!

Regarding the basement wall construction: it consists of cast-in-place concrete with a strength class of C 25/30 and is 24 cm (9.5 inches) thick, including 12 cm (4.7 inches) of perimeter insulation with extruded foam boards. I hope this will be suitable.

I wouldn’t worry about it in an insulated and heated basement. You only get condensation problems where walls are significantly colder than the indoor air.
