Hello,

I'm using OS 1.11, and I need DSOA object, so HVAC air loop to work properly. I've tryid to insert DSOA on sub-tab Loads in the Loads TAB, and OS is not assuming that load. Also, I've inserted DSOA on the LOADS tab, PROPERTIES sub-tab AIRFLOW "option" and although DSOA object stays were I put it, when I run the simulation, I get Severe error "Object=CONTROLLER:MECHANICALVENTILATION, name=CONTROLLER MECHANICAL VENTILATION 1, Required Field=[Zone 1 Name] was blank"

Can anyone tell me what I'm doing wrong and what I should be doing instedd?

Thankyou
