2 ESP-LX+ & LXi+ Installation, Programming, & Operation Guide
INTRODUCTION
LX+ and LXi+ Series Controllers
The ESP (Extra Simple Programming) -LX+, -LXi+ Series
controller is an irrigation timing system for residential and light
commercial use.
The ESP-LX+ comes in 6-, 8-, 12-, 16-, 20-, or 24-station
models, designed for either indoor or outdoor use. The
ESP-LXi+ comes in 8-, 12-, or 16-station models, for indoor use
only.
ESP-LX+ and ESP-LXi+ controllers bearing the
remote ready icon (shown at right) can be
connected to Rain Birds Radio Frequency (RF)
receivers (RM-1R & RMX-1R).
For example, the illustration on page 3 shows that station 1 is
currently watering. When station 1 is finished, the controller
will shut it off and start station 2. In the same way, station 3 will
begin watering when station 2 is finished.
NOTE: ESP-LX+ and -LXi+ controllers let you set a
delay between stations. For example, if you set a oneminute delay, station 1 will run until finished, followed
by a one-minute delay. Then station 2 will operate,
followed by a one-minute delay.
Controller Stations
Your ESP-LX+ or LXi+ Series controller is an electronic clock
that controls when your sprinkler system turns on, and how
long the sprinklers run. The controller has several sprinkler
stations connected to it, as shown in the illustration on the
following page. Each station is connected to a remote control
sprinkler valve.
The valve opens when it receives power from the controller,
and the sprinklers connected to that valve turn on. When these
sprinklers have run for their programmed time, the controller
shuts off the valve and opens the next valve in sequence.

➌ LCD Display during normal operation, displays the time
of day; during programming, shows the result of your
commands; during watering, shows the station that is
running and the minutes remaining in its run time (when
program dial is set to the AUTO position).
➍ Manual Start / Advance Button used to start a program
manually or to manually advance watering from one
station to the next. Also used to make program changes.
➎ PGM Button used to select watering program A, B, C, or
D-drip.
➏ Arrow / ON-OFF Buttons used to set times and days, and
to make program changes.
Programming Dial used to turn the controller off and on,
and for programming.

➑ Watering Suspended by Sensor LED glows when watering
is prevented by a moisture sensor.
➒ Sensor Bypass Switch used to tell the controller to obey
or ignore input from a moisture sensor system. (Sensor
systems are optional.)
➓ Stations Slide Switch used to select one of the station
rows around the Programming Dial. (For 12-, 16-, 20-, and
24-station models only.)
6 ESP-LX+ & LXi+ Installation, Programming, & Operation Guide
• Start time(s) - the time(s) of day that the program
begins; this is the time that the first station in the program
begins watering; all other stations in the program then
follow in sequence.
NOTE: The term start time refers to the time that a
program starts not to the time that each individual
station begins to run.
• Run time - the number of minutes (or hours and minutes)
that each station runs.
PROGRAMMING THE CONTROLLER
Programming Under Battery Power
If you wish, you can remove the front face panel of the controller and program the unit under battery power. This feature can
be useful if the controller is installed in an area that is not
readily accessible. This feature also lets you enter program
information before installing the controller at the job site.
Definitions
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 according to the program you set.
Each program contains:
• Watering days - the specific days of the week on which
watering takes place (for example, Monday, Wednesday,
Friday), or the watering interval (for example, every third day,
or only on even or odd days of the month).
To program the ESP-LX+ or ESP-LXi+ controller under battery
power, install the battery as described on page 62. To remove
the face panel, see the instructions on page 48. The controller
can be programmed under battery power, but should not be
operated on battery power alone. Connect the controller to an
AC power source as soon as possible to avoid battery drain.

Fill Out Programming Chart
Before you begin programming, fill out the Programming Chart
and attach it to the inside of the controller door. A sample
Programming Chart is shown on page 9. Follow these instructions to complete the chart.
➊ Describe the sprinklers or plant zones covered by each
station on the controller.
➋ Indicate which stations drive a master valve or booster
pump relay by checking ON in the MV / Pump column.
(See page 26 for more information).
➌ In the Program A column, for Custom cycle, circle the
specific days of the week; for Cyclical schedule, write the
cycle period (e.g., 3-day cycle means every third day);
for ODD/EVEN-day watering, check ODD or EVEN.
➍ Enter the start time for Program A. You may enter up to six
start times for each program, but only one is needed to run
the program.
NOTE: Start times apply to the program, not to the
individual stations assigned to the program. In this
example, Program A begins watering at 8:00 a.m. on
Mondays, Tuesdays, Thursdays, and Saturdays.
Station 1 runs for ten minutes, followed by Station 2
for 20 minutes, Station 3 for 20 minutes, and Station 4
for 5minutes. The entire program takes about an
hour.
➎ Enter the watering run time (in hours and minutes) for each
station assigned to Program A.
➏ Enter the water budget percentage by program. The water
budget for sample Program A is set to 80%.
➐ Enter the station delays for Program A. A station delay is
the time between the end of one stations operation and
the beginning of the next. Use a station delay to let a water
well recover or to allow slow-closing valves to turn off
completely. If neither of these situations applies to your
site, leave the station delay set to 0. A station delay setting
applies to all stations in the program.
In the sample chart, Program A has a one-minute delay
between stations. When Station 1 ends, the controller waits
one minute before starting Station 2. There will also be a
one-minute delay between Station 2 and Station 3, etc.
➑ Make any special notes in the space provided.
➒ Repeat steps 2 through 7 for Programs B, C, and D.
NOTE: Stations assigned to Program D cannot be
used in any other programs. See page 19 for more
information.

13ESP-LX+ & LXi+ Installation, Programming, & Operation Guide
Programs A, B, and C are not allowed to overlap each other. If
they are programmed to overlap, programs A, B, or C will
stack (run in consecutive order upon the completion of the
program in progress).
Program stacking prevents excessive flow demand and low
water pressure caused by having too many valves running at
one time.
NOTE: It is easier to select one program and program
it completely. Jumping from program to program can
be confusing.
Select Program
Four independent programs are available in the ESP-LX+,
LXi+ Series controller: A, B, C, and D-drip. Multiple independent programs let you enter watering schedules to meet the
requirements of different types of plant materials, soils, slopes,
shady or sunny areas, etc.
The D-drip program is designed for drip irrigation equipment.
Stations assigned to the D-drip program cannot be assigned
to any other program. The D-drip program can overlap, or run
concurrently, with programs A, B, or C.
