This model validates Buildings.Templates.Plants.Controls.Pumps.Generic.StagingHeaderedDeltaP in a configuration with four pumps.
The simulation of this model shows that when the lead pump is enabled, the output of the staging controller is greater than or equal to one. The number of enabled pumps increases and decreases with the varying flow rate and under the condition of a minimum runtime of 10 min. It remains greater than or equal to one as long as the lead pump remains enabled.
When the lead pump is disabled, the number of enabled pumps is set to 0. This transition is not subject to the minimum runtime.
