There are 3 chillers each with its own variable speed pump - looking at the chiller flow and evaporator cooling rate profiles it seems they are staging as expected

There are chillers, cooling towers, building load etc. (this is a model of a complete building.)

I'm working on a model with variable speed headered condenser water pumps.

I've used the HeaderedPumps:VariableSpeed with 2 pumps per bank, and have input values for the total rated flow and Rated Pump Head.

After running the model I've had a look at the Pump Electric Power output which shows the pumps are operating at constant speed.

Has anyone experienced this issue before? I'm unsure as to why the pumps are not operating at variable speed.
