.Buildings.Applications.BaseClasses.Controls.VariableSpeedPumpStage

Information

This model implements a simple staging control logic for variable speed pumps.

• When the mass flowrate in each pump is greater than a threshold, and the speed signal is greater than a threshold, then activate one more pump;
• When the mass flowrate in each pump is less than a threshold, or the speed signal is smaller than a threshold, then deactivate one more pump.
