Start-Up Genie
This controller is equipped with a Start-Up Genie which allows the user to easily configure
the controller for various pump control applications. The Genie configures parameters
that are based on the selections that are made by the user. The Genie allows the user to
configure the motor, application type, inputs, outputs, pump protection features, flow
compensation, and communications. The application types include single pump, constant
slave, duplex control, speed control, and test run mode. See the Setup and
Commissioning section for details.
