It shall NOT be possible to change or reprogram from the field thus assuring the operator full control at all times.

H. A “time window” may be defined for each individual program, confining its operation to this specific time period.

Individual programs shall be capable of being designated for up to six (6) start times. Individual schedules shall be capable of being designated for up to 12 start times within the specified time window for their program. It shall be possible to designate the sequence of operation of areas and the sequence of operation of stations in these areas, within a given schedule.

PRO software shall automatically increase or decrease system capacity according to these user-defined limits.

L. Programming Flexibility - The Cirrus PRO system shall also provide for programs to be set to adhere to manual water budgeting; at the system level, at the individual program level and/or at the individual schedule level. A watersaver feature shall provide water budgeting capabilities from zero (0) to 300% in one (1) % increments.

Automatic rain shutdown shall be possible with the integration of a rain sensor.

M. An innovative, guided initialization and “start-up” programming method in Cirrus PRO shall result in a customized

QuickStart™ program that gets the system “up” and “operating” in the shortest possible time.

Precipitation rates for each station shall be automatically calculated with the selection of sprinkler model, pattern and spacing.

N. A unique QuickIRR™ method of programming shall provide for a quick and easy method to automatically build programs to meet all irrigation challenges and allow programming by specific areas and designating sequence of operation of these areas. This feature is enhanced in Cirrus PRO by providing the ability to program multiple courses.

Select the course, hole, area, sequence and run time and Cirrus PRO will calculate the most efficient irrigation sequencing.

Irrigation Renovation Project 02811/9 10/25

O. A “Dry Run” feature shall provide for simulation of a program prior to operation, enabling the user to make the necessary adjustments before actually operating it in the field. A printout of the “dry run” results shall be possible, as well as being displayed on the monitor.

P. The Cirrus PRO Cycle + Soak™ feature works with Flo-Manager to achieve maximum efficiency and conservation. It helps control water application on slopes and in areas with poor drainage. Cycle + Soak shall maintain pump station demand while preventing over application in challenging areas of the course. The Cycle + Soak feature will ensure the maximum cycle time defined by the user is never exceeded and will not change with changes in station runtime.

Q. Graphical display of the golf course can be achieved using GPS, CAD, aerial photograph or the Scorecard function.

Each hole can be defined to indicate the areas to be irrigated such as greens, tees, fairways, approaches, perimeters, roughs and miscellaneous areas. The system shall provide for multi-station programming and operation of individual stations. A station data table shall give complete database information for each individual station.

R. The FREEDOM SystemTM - The Cirrus PRO system shall be capable of direct manual access of any station at any time. Full system remote control via handheld radio or remote telephone commands shall be possible with the integration of The FREEDOM System™ and handheld software module.

Estimator” feature shall provide projections of water and power costs for specific irrigation cycles, which can be used in establishing budget requirements.

T. When used with an Integrated Control System, the Cirrus PRO software shall contain detailed diagnostics software that measures a series of parameters related to system operation. These parameters shall include ICI and ICM operation. The software diagnostics shall be capable of polling individual station ICM’s on each wire path and display the number of passed and failed ICMs on each wire path. The diagnostics shall also be capable of measuring the total mA draw on each wire path. Individual ICM’s can be interrogated to confirm communication with the central control software as well as measure the voltage at each ICM for troubleshooting purposes. The diagnostics shall be capable of communicating with each ICM by “fast connect” or through the “long address” setting based on the diagnostic function.
