Answer: the air flow of the self-regulating CMV is constant, that of the hyroregulating CMV is modulated according to the indoor and outdoor humidity level.
A single flow CMV can be either self-regulating or humidity-regulating. The main difference between the two concerns the air flow. The self-regulating VMC provides a constant air flow, fixed in advance according to the characteristics of the accommodation and the number of occupants. The self-adjusting VMC does not take into account weather conditions (rain or wind) or the ambient humidity in the accommodation. With a humidity-controlled VMC, on the other hand, the air flow supplied is modulated according to the indoor and outdoor humidity level thanks to humidity sensors, in order to provide ventilation corresponding exactly to your needs. You guessed it, with this additional service, the humidity-controlled CMV is also more expensive than the self-adjusting… You too, send us your brico question
