Re: [EnergyPlus_Support] setpoint manager



A SetpointManager is basically a control point - it indicates the status to be maintained at that point in the loop.  For example, if you set the PlantLoop Supply Outlet Node to maintain a certain temperature, the equipment on the supply side of the plant loop will need to operate to maintain that temperature.  If the PlantLoop is a hot water loop and there is a boiler on the supply side, then the boiler might modulate to maintain the setpoint temperature.  Not all equipment is capable of maintaining all setpoints, so sometimes the setpoint is not met and other problems can result, but think about it as a desired state within the plantloop controls.

Hi ,
i read this about setpoint manager in I/O ref :
setpoint manager are one of the high level control construct in energyplus. A setpoint manager is able to access data from any of the hvac system nodes and use this data to calculate a setpoint for one or more other hvac system nodes.setpoints are then used by controllers or plant or condenser loops as goal for their control action ....."

but i dont undrestand it well especialy use of setpoint in the case of plant loop , could you please describe it please?

thanks
