Chilled water pump configuration

First of all, ASHRAE 90.1 models have been used to Calculat the HVAC capacity of large office buildings.(HVAC SIZING SIMULAION) The Chilled pump configuration of the Refrence model is ConstantPrimaryNoSecondary But, i want to know about the HVAC Capacity according to the chilled pump configuration. Ex) Class list _ HVACTemplate:Plant:chilledWaterLoopField _ chilled water Pump configuration Case 1. ConstantPrimaryNoSecondary Case 2. VariablePrimaryNoSecondary Case 3. ConstantPrimaryVariableSecondary (Reference Model)

Form Refrence Model to Case 1. Fatal error message below.
