Hi Khaled,
You define the pumps when you build your chilled water plant. In the plant
window, select the "Distribution" tab and then under Distribution System,
there is a drop down menu with three options; (1) Primary Only, Constant
Speed, (2) Primary only, Variable Speed and (3) Primary/Secondary, Variable
Speed Secondary. I've attached a screen shot.
