SetpointManager:Scheduled- Control Type MassFlowRate NOT working

edit

Hello,

I am trying to model DOAS which has seasonal OA mass flow. To model this, I am trying to use SetpointManager:Scheduled - Control Type MassFlowRate with which flow can be controlled in different seasons. However, I see constant airflow after applying the SetpointManager with desired Mass flow Rate as described in I/O file.

Any pointer will be appreciated in this regard.

Thanks,
