Dear all,
I have two rooms in the nursery, each is a separate zone due to a different usage profile. Both zones are served by the same mechanical ventilation system. In each zone, I set the max CO2 control at 1500 pp. Only in the first zone, the control works, in the second, a constant air flow is maintained all the time, regardless of the number of people in the room. What could the cause be?
Thanks for the help in advance.

Kind regards,
Slawka
