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