Abstract
An apparatus and method for controlling a flow parameter of a pump. The pump includes a pumping device for pumping fluid, the pumping device having at least one flow parameter. The pump further includes a control coupled to the pumping device and a control panel having a plurality of controls operable by a human. The control is programmable by operation of the plurality of controls, thereby allowing a human to program the at least one flow parameter of said pumping device by operation of the plurality of controls. The control has a lock that can be activated by operation of at least two of the plurality of controls. Upon activation, the lock prevents the alteration of the at least one flow parameter. The method includes the step of providing the pump of the present invention, programming the at least one flow parameter by operating the plurality of controls, and activating the lock by operating at least two of the plurality of controls.
