The Pump Startup Determination module monitors the Chiller Selector and determines whether the pumping subsystems should be enabled. This module prevents variable speed headered pumps from activating until the Chiller Selector has opened at least one isolation valve. The Pump Startup Determination module has eight Boolean inputs and a single Boolean output. This module is only needed for variable speed headered primary pumps because the Chiller Selector and the Pump Selector are decoupled from one another.
