OpenStudio currently creates plant operation schemes automatically depending on where you have the setpoint managers on the loop. If you have them on the outlet nodes of the individual components (boilers, etc), you will get a PlantEquipmentOperation:ComponentSetpoint. If you have them on the supply outlet node, you will get a PlantEquipmentOperation:HeatingLoad or PlantEquipmentOperation:CoolingLoad depending on the types of equipment on the loop. The logic to create these is pretty "clever," so it would not surprise me if you hit an odd scenario where the automation is failing to do what you expect. Also, perhaps a tangent, but the Boiler has a field called "Boiler Flow Mode" that impacts when/how flow through the boiler happens.
In the future, we will likely expose the plant loop operation schemes to the user in more detail so that you don't need to understand the translator to know what's going on.
