I suggest taking a look at the DOAToPTHP.idf reference model that's included in ExampleFiles of the EnergyPlus installation (attached, just change extension from .png to .idf). The system is described as:
Each AirTerminal:SingleDuct:Mixers specifies outdoor air flow rate for each zone with OutDoor Air Method = IndoorAirQualityProcedure in DesignSpecification:OutdoorAir to control indoor CO2 level below the setpoint.
