Hi, In my project I have made a EMS that controls the fraction of outdoor air based on the concentration of pollutants in the return air. However,I see that even though I manage to control the OA fraction with the EMS, the relief airflow does not change to be the same massflow as the outdoor air flow.

Do you know if I can control the relief? I have looked at the .eed file and I find it as System Node Setpoint,Mass Flow Rate Setpoint, but I dont seem to have something as I have for the OA AHU_OA_CONTROLLER,Outdoor Air Controller Maximum Mass Flow Rate,[kg/s]

Thanks !

Do you have any idea on how to make this control based on outdoor air temperature and relative humidity?

I am looking for something like that but I cannot find anything helpfull.

I don't even know how to create a measure or a EMS logic.
