Information

Heating-only plants with variable speed primary pumps that are not controlled to maintain differential pressure or flow setpoint

When commanded on, the primary HW pumps are commanded at a fixed speed yPumHeaWatPriSet, as determined during the Testing, Adjusting, and Balancing phase to provide the design heat pump flow.

Heating and cooling plants with common variable speed primary pumps that are not controlled to maintain differential pressure or flow setpoint

When commanded on, the primary pumps are commanded at a fixed speed yPumHeaWatPriSet in heating mode or yPumChiWatPriSet in cooling mode, as determined during the Testing, Adjusting, and Balancing phase to provide the design heat pump flow in heating mode or cooling mode.

Heating and cooling plants with separate variable speed primary pumps that are not controlled to maintain differential pressure or flow setpoint

When commanded on, the primary HW pumps are commanded at a fixed speed yPumHeaWatPriSet. When commanded on, the primary CHW pumps are commanded at a fixed speed yPumChiWatPriSet. The pump speed yPumHeaWatPriSet or yPumChiWatPriSet is determined during the Testing, Adjusting, and Balancing phase to provide the design heat pump flow in heating mode or cooling mode.
