Pumps in EnergyPlus

Hi,

In the pumps section of EnergyPlus, it asks for 4 coefficients which in order to have them I need to use pump curves for the following equation:

FractionFullLoadPower = C1 + C2PLR + C3(PLR^2) + C4*(PLR^3) which I am using from the EngineeringReference of EnergyPlus. I would appreciate it if someone can help me figure out what is the meaning of "FractionFullLoadPower" and "PLR" for a pump? I have the performance curve of my pumps.

Thanks,
