The Nimbus™ II
Central Control System
Easy, Intuitive Map-Based Irrigation Control. Now with RainWatch™

New Standard Mapping Features Simplify Control

Nimbus™ II allows you to integrate a custom map of your course using GPS or AutoCAD drawings*, or by importing a BMP or TIFF file. With your computerized course map, you can zoom-in to monitor every detail of your course. Determine individual rotor activity, monitor pump station activity and control the flow of water graphically. Just double-click on a station for a complete status report.

Start Without Reading A Manual

Rain Bird is the first in the industry to offer an integrated computerized set-up program. Quick Start™ is a training tool that guides the first-time user through the initialization and start-up of Nimbus II. Quick Start even helps users build their first customized programs and import a map—one step at a time. So, you can quickly get the system up and running without having to read through manuals or attend week-long programming classes. This startup program will teach you how to assign start and finish times to clearly define your watering window. And because each schedule can run up to 12 starts, many different turf growing conditions can be taken into account: germination, clay soil and steep slopes.

Make The Most Of Your Irrigation System

Nimbus II can operate 50 programs and 50 schedules per program at one time. Satellites or decoders can be assigned to multiple schedules, allowing you the flexibility to optimize costly hardware. The Course Monitor™ screen provides a graphical real-time view of the course with the ability to monitor activities at a glance.

RainWatch™ is an exclusive new feature that is so unique it is patented (US Patent #7,229,026). RainWatch is an intelligent rainfall reaction system that uses up to four tipping bucket rain cans to detect and react to local rainfall. For short duration cloudbursts, RainWatch suspends irrigation while simultaneously measuring the real time rainfall. When the storm passes, irrigation is resumed with station runtimes reduced by an amount equivalent to the measured rain. In case of extended rainy weather, irrigation will be cancelled for a user-definable period of time.

Flo Graph™ allows visibility of real-time graphics with individual station information presented in colorful charts. This feature monitors each or all pumps for reliable results.

Flo-Manager® balances system demand at maximum capacity with the efficiency of the pump station and delivery network. By staging pumps, Flo-Manager maximizes system output without causing undue stress to your pump system and components. It’s sure to help lower water demand, reduce system wear and tear and save energy—year after year.

Minimum ET™ is another new feature that helps promote healthy turf by supporting advanced ET management techniques. With the Minimum ET feature a superintendent can define a minimum ET threshold value that must be met before irrigation will take place. Minimum ET values can be assigned globally so they affect all programs, or individually by programs for the ultimate in ET management.

Cycle + Soak™ works with Flo-Manager to achieve maximum efficiency and conservation. It helps you control water application on slopes and in areas with poor drainage. Cycle + Soak maintains the pumping station demands while preventing over application in those
challenging areas of the course.

Water Budgeting allows you to react to changing conditions with ease. Make specific adjustments to the entire system, a single program or schedule—from 0 to 300 percent.

Virtual Weather™ provides Rain Bird the exclusive ability to generate evapotranspiration (ET) rates fromuser-defined values or optional Weather Station sensor data of wind, humidity, temperature, solar radiation and rainfall. This optional feature allows customized and intelligent ET creation for every application with or without a weather station.

Smart Pump™—Rain Bird’s Smart Pump Software links your pump station to your central control system providing real time communication and optimizing your irrigation cycle. Smart Pump also has the ability to monitor and react to changes in station capacity. Should the pump station capacity increase or decrease, the software adjusts the irrigation cycle based on this change. (Optional)

Works With Or Without Satellites

The optional hybrid modular software interface of the Nimbus II central control system gives you ultimate flexibility when choosing satellites and decoders for your course. Two-wire satellites, wireless satellites and decoders can all be used together with Nimbus II. It is the only system with the unique ability to operate the Rain Bird field decoders and Rain Bird satellites to provide efficient irrigation throughout your course. If you prefer, Nimbus II can control up to 224 Rain Bird PAR+ ES, PAR+ES LINK, PAR+, MSC+ and COM satellites, in addition to PAR+ LINK, MSC+ LINK and COM LINK sats.

Meet Regulatory Requirements

Nimbus II makes it easier to satisfy increasing regulatory requirements regarding water usage. Its record-keeping function in Print Office™ allows you to track the amount of irrigation that has been applied throughout the course for days, weeks and months at a time. Nimbus II’s true, two-way communication accurately logs station run time for precise data gathering. This data can be moved from one application to another so you can easily use it in reports that are generated in another program.

Get Precise Control At An Affordable Price

Don’t let the easy-to-use, no-nonsense controls fool you. The powerful mapping function of Nimbus II offers big league flow management, Cycle + Soak, Smart Sensors, Smart Weather™ adjustments and control of Rain Bird’s optional on-site Weather Station. Its superior mix of high-end features, graphic controls and affordable pricing make Nimbus II the perfect choice for superintendents who demand excellence.

Offers International Applications

In addition to English, the language of the Nimbus II can be changed to Spanish, French, German, Italian, Swedish, Portuguese, Korean, Japanese and Chinese. It can even use standard metric measurements to regulate hydraulic flow, eliminating the need for time-consuming conversions.

Control From Anywhere On The Course

The Rain Bird FREEDOM™ System adds a greater level of control to your Nimbus II system. This optional, handheld, two-way radio allows you to communicate with Nimbus II to stop, start or continue water application. It will also give you spot water without having to sit down in front of the computer. Add a FREEDOM-Pad™ system and gain more control with visual activation.
