Installation
Mount Controller
NOTE: Choose a suitable mounting location close
to a 120VAC wall outlet.
Drive a mounting screw into the wall, leaving an
A
1/8 inch gap between the screw head and the
wall surface (use the supplied wall anchors if
necessary), as shown.
Locate the keyhole slot on back of the controller
B
unit and hang it securely on the mounting screw.
A
Open the front panel, and drive three additional
C
screws through the open holes inside the
controller and into the wall, as shown.

B
Connect Valves
Route all field wires through the opening at the
A
bottom or back of the unit. Attach conduit if
desired, as shown.
WARNING
Do not route valve wires through the same opening as power wires.
Connect one wire from each valve to the terminal
B
on the Base Module or Station Module that
corresponds to the desired station number (1-22).
Connect a field common wire to the COM
C
(common)terminal on the Base Module. Then
connect the remaining wire from each valve to
the field common wire, as shown.
To perform a Valve Test, connect the common wire
D
to the COM terminal and the power wire to the VT
terminal. This will immediately turn the valve ON.
Connect Master Valve (optional)
Connect a wire from the master valve to the MV
E
(master valve) terminal on the Base Module.
Then connect the remaining wire from the master
valve to the field common wire, as shown.

Station Numbering
EN
The controller is configured with “fixed station numbering”, meaning that Bays Two, Three and Four can
accept either a 3 or a 6-Station Module. If a 6-Station
Module is NOT installed then the unused stations are
reserved for future use.
Example of Station Numbering when using two
3-Station Modules. A total of 10 stations are installed.

VT MV COM
• The Base Module is installed in Bay One and uses
Stations 1 through 4.
• A 3-Station Module is installed in Bay Two and
uses stations 5 through 7. Stations 8 through 10 are
skipped and will be unavailable.
• A 3-Station Module is installed in Bay Three and
uses stations 11 through 13.
During programming, the controller will skip any
unused stations, creating a gap in station numbering.
The unused stations will show on the display as 8SKIP,
9SKIP, etc.
If the screen displays 20NOMOD where the 20 is flashing, then there is no module installed for that station
number.
Complete Controller Installation
Reinstall and reconnect the front panel.
A
Apply power to the controller and test the system.
B
NOTE: The electrical connections can be checked
even if water is not available. If water is available
and you would like to test some or all of your
stations, use the Test All Stations feature of the
controller.

required for runoff to begin and that there be
adequate soak time before the next irrigation
cycle of that same station begins again.

Program-Based Scheduling
EN
The ESP-ME3 uses a programmed-based scheduling
method to create irrigation schedules. This means all
stations with a run time on the program will run in
numerical order.
Manual Watering Options
Test All Stations
Start watering immediately for all programmed
stations.
Common Programming Error
The most common programming error for any program-based controller is to set multiple Program Start
Times that cause watering cycles to repeat.
As an example: Program A has a 1st Start Time set to
run at 8:00 AM. But then a 2nd Start Time has mistakenly been set for 8:15 AM, which means that all stations would water a 2nd time.
In this example, a 3rd Start Time has mistakenly been
set for 8:30 AM. Which means all stations would water
a 3rd time. The desired watering time was 45 minutes,
or 15 minutes per station. The actual is 2 hours and 15
minutes, which is excessive watering!

Troubleshooting
Error Detection
The ESP-ME3 controller has built-in error detection
that can automatically generate an ALARM caused by
an essential programming error or if an electrical short
condition is detected.
The ALARM LED light on the ESP-ME3 controller front
panel will light up to indicate an alarm condition:
Programming Errors (blinking LED)
NOTE: Program information is stored in nonvol-
atile memory so it is never lost if the front panel
loses power.
Replace the front panel (refer to Complete
D
Installation in the Installation section).
NOTE: After the front panel is re-installed, any
station that does not have a corresponding Station Module installed will function as though the
run time is zero.
Battery Life
If the display repeatedly shows “-- -- -- -- --”, or there
is no display when using a 9V battery for remote programming, replace the battery.

percent limit can be adjusted in the Rain Bird App
when used with LNKTM WiFi Module. If a High Flow condition is detected, a “High Flow Alarm” is shown at the
display and the red alarm LED comes on. To clear the
alarm press the “Hold to Start” right arrow button during the alarm message.

Federal Communications Commission
This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one
or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/television
technician for help.
FCC Regulatory Safety Notice and IC Canada
Statements
The Class B apparatus meets all requirements of the Canadian
ISED (formerly IC) regulations - CAN ICES-3 (B)/NMB-3 (B).
Cet appareil de classe B respecte toutes les exigences de la
réglementation canadienne ISED (anciennement IC)- CAN
ICES-3 (B)/NMB-3 (B).
Safety Information
WARNING
Special precautions must be taken when valve
wires (also known as station or solenoid wires)
are located adjacent to, or share a conduit with
other wires, such as those used for landscape
lighting, other “low voltage” systems or other
“high voltage” power.
Separate and insulate all conductors carefully,
taking care not to damage wire insulation during installation. An electrical “short” (contact)
between the valve wires and another power
source can damage the controller and create a
fire hazard.
All electrical connections and wiring runs must
comply with local building codes. Some local
codes require that only a licensed or certified
electrician can install power. Only professional
personnel should install the controller. Check
your local building codes for guidance.
If the supply cord of an outdoor controller is
damaged, it must be replaced by the manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
If the supply cord of an indoor controller is
damaged, it must be replaced by a special cord
or assembly available from the manufacturer
or its service agent.
Outdoor controller shall be permanently connected to fixed wiring by a flexible cord, and
have a cord anchorage. The cord anchorage
shall relieve conductors from strain, including
twisting, at the terminals and protect the insulation of the conductors from abrasion.
CAUTION
Stationary appliances not fitted with means for
disconnection from the supply mains having
a contact separation in all poles that provide
full disconnection under overvoltage category
III, the instructions state that means for disconnection must be incorporated in the fixed
wiring in accordance with the wiring rules
NOTICE
Use only Rain Bird approved accessory devices.
Changes or modifications not expressly
approved by Rain Bird could void the user’s authority to operate the equipment. Unapproved
devices may damage the controller and void
the warranty. For a list of compatible devices
