hi everyone, i have a question for you. I would like to create a ventilation system like this, tell me if it is possible: the outdoor air gets in in a zone A, it cools down the zone A, then it is sucked in zone B and gets out from the thermal zone B.

B. I read many similar post but I don't understand. Now I'm using a mix air between two zone with whit "air wall". I don't know how to implement the solution with several zones.zones. thank you!!
