- What is iCentral?
iCentral is the first Internet based Central Control Irrigation System. By logging on to Rain Master's iCentral website, users may control, monitor, and manage their irrigation needs via the internet.
What specific functions can iCentral perform?
- Command and control.
- Users may enter, modify, or view irrigation
schedules for any iCentral enabled Rain Master Eagle controller
using the internet.
- Water conservation.
- iCentral monitors your local weather on a daily
basis and automatically adjusts your controller's irrigation
schedules based upon plant watering needs.
- iCentral monitors your local area rainfall and
automatically performs a rain shutdown to your controllers.
Similarly, iCentral intelligently restores your system back to the
automatic watering mode when irrigation is required.
- Timely maintenance.
- Automatically take appropriate corrective action
if and when field anomalies occur (i.e. broken heads, pipes, faulty
station wiring and flow problems.)
- Smart alerts® provide immediate user notification
via email to your cell phone, computer, or any email capable device.
These notifications inform you where the problem is, what the
problem is, and at what time the problem was detected.
- Irrigation management tools.
- Command a manual rain shutdown or resumption of
automatic watering from the internet.
- Start or stop irrigation of any station or program
from the internet
- Management reports
- water usage
- system anomalies/alarms
- Sensor and weather station reports
- Irrigation Schedule reports
- Operator scheduling and usage reports
- "Intelli-Sync" control.
- Your Eagle controller and iCentral allow programming
changes to be performed either in the field or at iCentral. Intelligent
synchronization (Intelli-Sync®) processing notifies the iCentral web
user any time a field programming change has occurred at any controller.
The iCentral user may then elect to accept or reject the field
- Intelli-sync® ensures that your controller's
date/time is always correct by accounting for daylight saving time
transitions, or inadvertent date/time adjustments at the controller.
- What do I need to use iCentral?
order to use the iCentral system you need a Rain Master Eagle controller
and the corresponding "iCentral" communication card. The controller and
communication card may be purchased as a package or the iCentral card
may be added to any existing Eagle controller at any time. The iCentral
card includes a small antenna which mounts directly on the underside of
the enclosure. Once the installation is complete, proceed to the Rain
Master website at www.rainmaster.com
and click on the "iCentral" icon. The website guides you through initial
user account creation, and directs you to "activate" your controller.
Once service activation is complete, the power and benefits of the iCentral system is at your fingertips.
- How exactly does iCentral save me money?
Rain Master's iCentral system saves money for installation contractors,
maintenance contractors, and end users in several ways:
- Because the iCentral system uses wireless
technology, installation costs are minimal. Costs associated with the
complexities of phone line installation, and/or trenching for
communications wires are non-existent with iCentral installations. A
typical iCentral installation for a wall mount controller has three
steps: (1) hang the controller on the wall (three screws) (2) mount the
small antenna to the enclosure (An enclosure knockout is provided) (3)
wire the AC power, ground, and station wiring connections in the
- End users benefit from iCentral water savings
capabilities. Water savings occur when iCentral is setup to adjust
irrigation schedules using daily weather data (i.e. evapotranspiration
information as well as rainfall). Typical water savings range from
20-35% depending on your current systems operating variables and your
schedule adjustment practices.
- Maintenance contractors save money because minor
adjustments and schedule changes can be made effortlessly from the
office. Adjustments may include scheduling changes, rain shutdowns, and
or manual irrigation cycles. Because control is provided through the
internet, maintenance contractors may instantly respond to owners
requests for field changes thereby negating the need for physical
- Maintenance contractors may elect to "lockout" field
programming changes at the controller in order to ensure that schedules
are not mis-programmed in the field. Mis-programmed controllers may
result in damage to a landscape as well as being a potential source for
- Both maintenance contractors and end users benefit
from the 24 hour round the clock monitoring activity performed by
iCentral. Your Eagle controller has the ability to respond to field
anomalies, i.e. broken heads, pipes, and mainlines in an immediate
fashion, thereby eliminating runoff, damage to landscapes, and potential
lawsuits. Once a problem area is detected, the controller takes the
appropriate corrective action. Lastly an email is sent to your cell
phone and/or PC in order to inform the user/Maintenance contractor of
the specific problem condition.
- What are the advantages of using the internet over
conventional central control systems?
- Affordable low-cost central. The iCentral design utilizes one
electronics card that plugs directly into your existing Eagle
controller. With a minimum of components to purchase, your capital
equipment expenditures are minimized.
- Installation Simplicity. Because iCentral utilizes existing
infrastructures such as the internet and wireless carriers, your installation is
simple and inexpensive. There are no phone lines to install, no hardwire to
trench, no expensive hardware investments in radio communications networks,
repeaters or radio site surveys. (refer to: "How exactly does iCentral save me
- High reliability. Since the system components are minimal,
there are fewer components to fail, less cables to get inadvertently
unplugged, and greater system uptime.
- No software required. Because your central is internet based,
there is no software to purchase or load. Software upgrades are no
longer an issue. You receive the latest features and capabilities each
time you logon to the website.
- No software backups or lost irrigation schedules. No need to
worry about software backups, crashed disk drives, or lost irrigation
schedules. Your irrigation schedules and all your account information is
maintained indefinitely by the Rain Master iCentral web servers. Your
irrigation schedules are also resident at your Eagle controller in
- No training required. The iCentral website has been designed to be an
intuitive learning experience. Simple screens with explanatory text ensure that
you will be using your iCentral capability from the moment that you first
"logon". Should you have a question, your Rain Master support team is a
toll-free call away.
- Smart Alerts®. You receive irrigation maintenance notifications
via email on your cell phone, and/or PC, at the time that any system
anomalies occur. These messages inform you where the problem is, what
the problem is, and at what time the problem was detected.
- Unlimited access/availability. Manage your irrigation system
from work, home, or anywhere you have an internet connection.
- No radio license required. No need to worry about license fees,
applications, availability of spectrum, and lengthy license turnaround
- I am apprehensive about using new technologies, how
can I be assured that this really works.
Rain Master has specialized
in irrigation control systems since company inception in 1981. At Rain
Master, control is our only business. Through the years Rain Master has
developed a reputation as the industry leader for innovative central
control technology. The Eagle/iCentral is no exception. The Rain Master
Eagle intelligent water management controller was first introduced on
April 15, 2002. The iCentral internet communications capability was
released after the successful completion of six months of extensive beta
testing which culminated June 1, 2003. The iCentral website was
officially launched on June 9th, 2003.
- What if I lose connectivity to the internet or the
wireless service to my controller is temporarily interrupted or lost? Will
my controllers still irrigate?
Absolutely. Your Eagle controller is
not dependent upon the internet or the wireless service to irrigate. All
of the irrigation schedules are executed from the controller. The
controller can continue to operate with its present schedule
indefinitely. If you were using daily weather information sent via the
internet and communications were lost, the controller will utilize
historic weather information from its non-volatile memory in order to
intelligently irrigate your landscape. When service is restored the
controller will automatically resume usage of the daily weather
information sent via the internet.
- I do not have much computer knowledge and I am
concerned that I will not understand how to use the iCentral website. Is
this technology difficult to learn?
The iCentral website has been
designed for the novice. The site has been designed so that no training
is necessary. Navigation is simple and explanatory text accompanies each
area that you traverse to.
When it comes to programming any "stand-alone" controller, virtually
all manufacturers' controllers have a learning curve of some type. When
using the iCentral website, the learning curve is virtually eliminated
because the website operations are both intuitive and simple. All of the
controller functions are actually much easier to use on the website than
from the controller front panel.

- What types of field problems (faults) can
the controller detect and how will I be notified?
The Eagle with
iCentral card will monitor for Wiring Faults, Mainline Flow limits,
Unscheduled Flow, No Flow, and Upper Flow limit violation on a per
station basis. You can configure the iCentral system to notify you in
real time via email or text message to any capable cellular phone or
email account. In addition to the email, the website will show an alarm
icon indicating that field problems have been detected.
- The Rain Master "iCentral" system can
deliver site specific weather information to my controller. Where does
this information come from?
The daily weather information may come
from a variety of sources depending on your location.
- Users anywhere in the United States may use Rain Masters ZipETTM
service. The ZipET service will automatically deliver Zip Code specific
evapo-transpiration (ET) data to your controller on a daily basis.
(refer to FAQ 15)
- You may purchase a Rain Master weather station and connect it to one
of your Eagle controllers. Rain Master will then read and distribute
this data to any of your "other" Eagle controllers automatically.
- California users may get daily ET data from any of California's
CIMIS weather stations. Rain Master automatically downloads this
information from CIMIS every day and re-distributes it to your
- What is ZipETTM and how does it work?
ZipETTM is a revolutionary ET (evapo-transpiration) data collection and
dissemination service for Rain Master iCentral Internet customers. Using
ZipETTM users can get site specific daily ET weather data (based on Zip
Code) delivered to any controller located within the United States.
Using daily ET, your Eagle controller automatically adjusts irrigation
watering schedules based on daily weather conditions so you only replace
water that has been depleted from the soil.
Unlike other ET-based irrigation programs that require you to have water
audit expertise or to be a soil scientist, Rain Master's ZipETTM only
requires you to enter a 5-digit Zip Code. The rest is automated! Your
irrigation schedules adjust everyday based upon receipt of this daily
So how does it work? Rain Master receives reliable raw weather
information on a daily basis from thousands of federally regulated FAA
and NOAA weather stations throughout the United States. The weather
information is validated, and converted as necessary in order to
generate industry accepted ET values. The ET values are interpolated by
Zip Code using a three-dimensional surface regression model. Site
specific ET information is then delivered to your controller based upon
your designated iCentral weather setup criteria.
