INTRODUCTION
Ec Controller
Thank you for purchasing a Rain Bird Ec irrigation system
controller. This manual shows how to install, program, and
operate your controller. Please read these instructions carefully
and keep this manual in a handy place for future reference.
The Rain Bird Ec is a compact, easy-to-use controller that
offers the following features:
•Three programs, with independent watering days
•Up to four watering start times per program
•Option to set any day of the week as a watering day
•Water budgeting feature across all programs
•Battery backup to retain time, date, and programming
during power outages
•Three year warranty
CERTIFICATE OF CONFORMITY TO EUROPEAN DIRECTIVES
Rain Bird declares that the Ec device, an irrigation controller, conforms to the 72/23/CEE European
Directives for electrical safety and to 89/336/CEE and 93/31/CEE concerning electromagnetic
compatibility. The applicable standards in accordance with the technical file are :
EN 60065 for electrical safety.
EN 50081-1 ed 92 for interference.
EN 50082-1 ed 92 for interference resistance.
The Ec type device is powered by 230V~,50Hz,
single phase.

5Ec Controller
You will need to understand the following terms to successfully
program your Ec controller.
•Watering day cycle  The period of days in which the
controller repeats the program you set. For example, a 7-day
cycle is a weekly schedule that repeats once every seven
days. A 2-day cycle repeats every other day.
•Watering days  The specific days within the watering
day cycle when watering takes place. In a 7-day cycle, you
may select multiple watering days within the cycle. For
example, you might water on day 1 (Monday), day 3
(Wednesday), and day 5 (Friday). In a 1- through 6-day
cycle, day 1 is always the only watering day. A 2-day cycle
waters on day 1, skips a day, and then waters again on day 1
as the cycle repeats. A 3-day cycle waters on day 1, skips 2
days, and then repeats.
•Start time  This is the time, or times, the first station in
a program begins watering. All other stations in the program
then follow in sequence.
NOTE: The term start time refers to the time the
program begins  not the time each individual
station begins to run.
•Run time  The number of minutes that each station
runs.
Controller Stations
DIAGRAM 1
The Rain Bird Ec controller is an electronic timer that controls
when your sprinkler system turns on, and how long the
sprinklers run.
Depending on the model, the Ec can control four, six, or nine
watering stations. Astation is a series of sprinklers, or other
irrigation devices, connected to a common remote control
valve. When the valve receives a signal from the controller, the
valve opens and turns on the sprinklers connected to it.
This illustration shows a diagram of a station layout. Station 1
is currently watering. When station 1 finishes, the controller
shuts it off and turns on station 2. When station 2 finishes
watering, station 3 begins, and so on.
What Is a Program?
Programming is the process of telling the controller exactly
when and how long you want to water. The controller opens
and closes the remote control valves for each station according
to the program you set.
The Ec offers three independent programs; A, B, and C. Each
program controls from one to six stations, and lets you
customize your watering schedules to meet the needs of
different types of plants, soil conditions, slopes, shady or
sunny areas, etc.

6Ec Controller
CONTROLLER BASICS
Programming Under Battery Power
If you wish, you can program the controller under battery
power. This feature can be useful if the controller is installed
in an area that is not readily accessible. This feature also
allows you to enter program information before installing the
controller at a job site.
To program the Ec controller under battery power, you must first
install the battery.
NOTE: To save battery power, the Ec goes into
Sleep mode after 40 seconds of inactivity on
the programming dial or buttons. Press any button
once to reactivate the controller.
Installing the Battery
DIAGRAM 2
The battery back-up feature retains time, date, and
programming information during power outages. The battery
also lets you program the controller under battery power
before it is connected to an AC power supply.
For best results, use a long-life, 9-Volt alkaline battery. A new
battery will normally provide power for up to one year. Replace
the battery yearly to ensure an uninterrupted power supply.
NOTE: Make sure the controller is connected to an
AC power supply when replacing the battery, or you
will lose all programming information including
date and time.
To install the battery:
1. Remove the controllers lower access cover to expose the
battery compartment.
2. Snap the two-wire battery clip onto the terminals of the
new battery. If you are replacing an old battery, dispose of
the old battery properly.
3. Insert the new battery snugly into the battery
compartment.
4. Replace the lower access cover.
Diagnostic Circuit Breaker
DIAGRAM 3
If the Ec controller detects an electrical short circuit on one of
the sprinkler systems station wires or valve solenoids, the
controller automatically shuts off the station with the fault. After
30 to 40 seconds, while it checks again to confirm the fault,
the controller advances to the next working station in the
program.

7Ec Controller
Every three seconds, the LCD displays the problem stations
number and the letters Err. The controller will continue to run
each operable station in the program. As each station is
running, the controller (at an alternate 3-second interval)
displays the working stations number and run time remaining.
When the controller finishes the program, it will continue to
display the problem stations number and the Err message.
After the program finishes, you should isolate and repair the
short circuit. Short circuits occur most frequently in the valve
solenoid (the plastic-encapsulated coil on the valve with the
two wire leads), or in the wire connectors to the valve leads.
After you find and repair the short circuit, turn the programming
dial to AUTO. Then press ENTER to clear the Err message
from the display. You may wish to operate the station manually
to make sure it works properly. (See Manually Run a
Station(s) on p. 19).
The LCD display shown in Diagram 3 indicates that the
controller has detected a short circuit on station 2.
Controls and Indicators
DIAGRAM 4
This illustration shows the programming controls on the face
of the Ec controller. These controls include:
1. Liquid Crystal Display (LCD)  During normal
operation, displays the time of day and the programs that
will run today. During programming, shows the results of
your commands. During watering, shows the station that is
running, the minutes remaining in the stations run time,
and whether another program is waiting to water.
2. + and - buttons  Set start times and days, and make
programming changes.
3. Programming dial  Turns the controller to OFF or
AUTO modes, and selects other programming functions.
4. PROGRAM button  Selects watering programs A, B,
or C.
5. ENTER button  Enters programming commands, and
starts manual operation.

Controller Programming Chart
Before programming your Ec controller, fill out the
Programming Chart included with your controller. Then
program the controller in the order shown on the Programming
Checklist.
1. Select the watering day cycle you wish to use, and circle
the watering days within the cycle. In the example shown for
program A, the operator has chosen a 7-day watering cycle
and circled M, W, and F as watering days. This means that
program A will water every Monday, Wednesday, and Friday.
NOTE: If you plan to use only one program for
your watering needs, select program A.
2. For program B, the operator selected a 3-day watering
cycle. With these selections, program B will water once,
skip two days, and then water again on the first day of a new
three day cycle.
3. You may also choose three special watering day cycles that
do not require you to select watering days. These cycles are:
•Ev = Waters only on even-numbered days of the month.
•Od = Waters only on odd-numbered days of the month.

9Ec Controller

10 Ec Controller
•Od31 = Waters only on odd-numbered days of the month,
but not on the 31st of any month or on February 29. (This
watering day cycle complies with special ordinances in
some water-restricted areas).
4. In the Program Start Times box for program A, write the time
you want the program to begin watering. You may assign up
to four start times to each program. If you want the program
to water only once each watering day, enter only one start
time. Enter other start times only if you want to repeat the
entire program more than once each watering day.
5. Enter the start time(s) for program B (if any). In the example,
Program A begins watering at 7 a.m. ProgramB begins
watering twice each watering day, once at 5 a.m. (05:00)
and again at 3 p.m. (15:00)
NOTE: If the total run time for one program
overlaps the start time for a second program, the
controller will automatically stack the programs
and delay the start time of the second program
until the first program finishes watering.
6. Next to each station number, enter a brief description of the
area covered by each controller station. Remember, a
station is a set of sprinklers operated by one remote
control valve.
7. In the Run Time column for each program, enter the
number of minutes you want each station to run.
Notice that stations 1 through 4 are assigned to program A,
while stations 5 and 6 are assigned to program B.
The Ec allows you to use the same station in multiple
programs for special watering needs. However, for most
applications, choosing not to repeat a station makes
programming simpler.
NOTE: Any Water Budget setting applies to all
programs (A, B, and C).

scheduled.

18 Ec Controller
Adjust Water Budget
DIAGRAM 20 & 21
Adjusting the Water Budget feature is the easiest way to
increase or decrease the run times of all stations on a program.
You can use Water Budget to decrease watering during cool
winter months, or to increase watering during hot, dry periods.
You can set the Water Budget percentage from 10% to 200%
(all station run times doubled), in increments of 10%.
Changing the Water Budget percentage affects all stations
on all three programs (A, B, and C).
Water Budget percentages are calculated on the normal
programmed run time for each station. For example, if a station
is programmed to run for 10 minutes, and you set the Water
Budget to 80%, the station will only run for 8 minutes (80% of
10 minutes). If you set the Water Budget to 120%, that same
station will run for 12 minutes (120% of 10 minutes).
NOTE: Water Budget will not split a minute. One
whole minute is the lowest run time allowed.
1. Turn the programming dial to WATER BUDGET.
2. The number 100 appears in the display. This indicates
that all stations are running at 100% of their programmed
watering time.
Auto Mode

1. To return the controller to automatic operation, turn the
programming dial to AUTO.
2. When the controller is NOT watering, it displays:
•Any program (A, B, C, or none) scheduled to water today
•The current time
• %A %B %C, if there is a water budget setting other than
100%
3. When the controller IS watering, it displays:
•The program that is running
•The station number currently running
•The watering time remaining for that station
• %A %B %C, if there is a water budget setting other than
100%

19Ec Controller
3. Press + to increase the Water Budget percentage, or press -
to decrease the Water Budget percentage.
4. When the Water Budget percentage is set to any figure other
than 100, all programs (A, B, and C) display a percent sign
(%) in front of the program letter.
5. After setting the Water Budget percentage, turn the
programming dial back to AUTO. All station run times will
be increased or decreased by the selected Water Budget
percentage.
Manually Run Stations and
Programs

3. To choose another program, press the PROGRAM button
(ABC) until the desired program letter appears in the
display.
4. Press ENTER to start the selected program.
NOTES: You can stack two or three programs to
operate manually by pressing ENTER after
selecting each program.
The controller runs stacked programs in order (A,
then B, then C), no matter in which order you stack
them. For example, if you start program B, then
stack program C, then program A, the controller
will finish B, and then run A, and finally C.
5. Turn the programming dial back to AUTO. The letter of the
manually operating program (A, B, or C) appears in the
display. Any stacked programs flash until their turn to
run.
NOTE: Water budgeting does apply to manually
operated programs.
After the last manual program runs, the controller returns to
AUTO mode and awaits the next scheduled program start time.
NOTES: Manually operating a station does not
affect the stations run time(s) in the automatic
programs (A, B, or C).
Manual operation cancels the operation of any
automatic program in progress. Also, Water
Budgeting does not affect manually operated
stations.
Run a Test Program
DIAGRAM 25
The controllers built-in test program will run each station that
has a non-zero watering time. When you run the test program,
the controller operates each station in numerical sequence,
from lowest to highest. You can use this feature to check the
operation of all sprinklers in the system.
1. To test all controller stations, turn the programming dial to
TEST.
