A method, computer system, and computer readable medium for facilitating selection from a plurality of devices, each device defined by a selection range dependent on at least a first parameter and a second parameter, the first parameter and the second parameter being correlated. The method includes: displaying on a graphical interface screen a graph of the first parameter versus the second parameter, the graph having displayed thereon a plurality of regions representing the selection ranges, receiving selection of at least a point of the graph from an indicator overlaid onto the graph and which is moveable on the graphical interface screen based on control from an input device, and in response to the selection, displaying on the graph only the regions which are relevant to the selected point.

1. A method for facilitating selection from a plurality of devices for operation in a system that has load requirements represented by a first parameter and a second parameter, the method being implemented by a processor and comprising: generating for display on a graphical interface screen a graph of the first parameter versus the second parameter, the graph having displayed thereon a plurality of regions, each region representing a selection range of one of the plurality of devices that is dependent on at least the first parameter and the second parameter, the first parameter and the second parameter being correlated, wherein each device includes a variably controllable motor;receiving selection of at least a point of the graph from an indicator overlaid onto the graph and which is moveable on the graphical interface screen based on control from an input device, wherein the point is a design point of the system, that represents a maximum expected operating point for the system; andin response to said selection, generating for display on the graph only the regions that overlap with the selected point and zooming within the graph to the selected point, wherein the selection range of the devices having the overlapped regions with the selected point are optimized for operation of their variable controllable motor at part loads for the design point of the system,wherein one of the devices having one of the overlapped regions is for operation in the system. 2. The method as claimed in claim 1, further comprising, when displaying the graph having only the relevant regions, receiving a further command through the graphical interface screen and in response generating for display a listing of the devices having the relevant regions. 3. The method as claimed in claim 2, wherein the listing of the devices is listed in a priority order. 4. The method as claimed in claim 1, wherein the indicator includes a pointer icon. 5. The method as claimed in claim 1, wherein the indicator includes an intersection of a first indicator line indicating the first parameter on the graph with a second indicator line indicating the second parameter on the graph. 6. The method as claimed in claim 1, wherein the devices are variable speed devices. 7. The method as claimed in claim 1, wherein the devices are variable speed control pumps. 8. The method as claimed in claim 1, wherein the first parameter is a pressure parameter or a flow parameter and the second parameter is the other of the pressure parameter or the flow parameter. 9. The method as claimed in claim 1, wherein the graphical interface screen is generated from a server. 10. The method as claimed in claim 9, wherein the server is a web server accessible over the Internet. 11. A computer system for facilitating selection from a plurality of devices for operation in a system that has load requirements represented by a first parameter and a second parameter, the computer system comprising: a processor; andmemory for storing information of a plurality of devices and of a selection range for each device dependent on at least a first parameter and a second parameter, the first parameter and the second parameter being correlated, wherein each device includes a variably controllable motor;the processor being configured to execute instructions stored in memory to:generate for display on a graphical interface screen a graph of the first parameter versus the second parameter, the graph having displayed thereon a plurality of regions, each representing one the selection ranges,receive selection of at least a point of the graph from an indicator overlaid onto the graph and that is movable on the graphical interface screen based on control from an input device, wherein the point is a design point of the system, that represents a maximum expected operating point for the system, andin response to said selection, generate for display on the graph only the regions that overlap with the selected point and zooming within the graph to the selected point, wherein the selection range of the devices having one of the overlapped regions with the selected point are optimized for operation of their variable controllable motor at part loads for the design point of the system,wherein one of the devices having the overlapped regions is for operation in the system. 12. A non-transitory computer readable medium having instructions stored thereon executable by a processor for facilitating selection from a plurality of devices for operation in a system that has load requirements represented by a first parameter and a second parameter, the instructions comprising: instructions for generating for display on a graphical interface screen a graph of the first parameter versus the second parameter, the graph having displayed thereon a plurality of regions, each region representing a selection range of one of the plurality of devices that is dependent on at least the first parameter and the second parameter, the first parameter and the second parameter being correlated, wherein each device includes a variably controllable motor;instructions for receiving selection of at least a point of the graph from an indicator overlaid onto the graph and that is moveable on the graphical interface screen based on control from an input device, wherein the point is a design point of the system, that represents a maximum expected operating point for the system; andinstructions for, in response to said selection, generating for display on the graph only the regions that overlap with the selected point and zooming within the graph to the selected point, wherein the selection range of the devices having the overlapped regions with the selected point are optimized for operation of their variable controllable motor at part loads for the design point of the system,wherein one of the devices having one of the overlapped regions is for operation in the system.
