.Buildings.DHC.Plants.Combined.Subsystems.Validation.MultiplePumpsDp .Buildings.DHC.Plants.Combined.Subsystems.Validation.MultiplePumpsDpThis model validates Buildings.DHC.Plants.Combined.Subsystems.MultiplePumpsDp by comparing an instance of that model with two instances of Buildings.Fluid.Movers.FlowControlled_dp connected in parallel. The two pumps are commanded On one after the other as they receive an increasing differential pressure setpoint and work against a two-way modulating valve that gets progressively opened.
