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.
1/8 IN.

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.

Connect a wire from the PSR (pump start relay)
A
to the MV (master valve) terminal on the Base
Module. Then connect another wire from the
pump start relay to the field common wire, as
shown.
To avoid the possibility of damage to the pump,
B
connect a short jumper wire from any unused
terminal(s) to the nearest terminal in use, as
shown.
NOTICE
The ESP-ME3 controller DOES NOT provide power for a pump. The relay
must be wired according to manufacturer instructions.
Only the following Rain Bird pump start relay models
are compatible with the ESP-ME3:
Description Note Model No.
Universal Pump Relay 110 volt only PSR110IC
Universal Pump Relay 220 volt only PSR220IC
Connect Flow Sensor (optional)
NOTE: Install the flow sensor in the field accord-
ing to the manufacturer’s instructions.
Run the flow sensor wires to the controller.
A
WARNING
Do not route valve wires through the same opening as power wires.
Connect both flow sensor wires to the Flow
B
terminals, as shown. Be sure to connect the
positive (sometimes red) sensor wire to the red
(+) terminal and the negative (sometimes black)
sensor wire to the grey (-) terminal.

NOTE: Connection to
pump and external
power not shown.

Flow Sensor Settings
Set the controller to obey or ignore a flow sensor.
When set to Sensor ON, automatic irrigation will
be suspended per station if detected flow exceeds
learned flow by more than 30%. When set to Sensor
OFF, all stations will ignore the flow sensor.
Turn the dial to Flow Sensor.
• Press
OFF (sensor off).
or to select SENS ON (sensor on) or SENS

NOTE: When switching from Sensor OFF to Sen-
sor ON, the controller will begin to LEARN FLOW.
It will run each station for short period to set the
expected station flow.
NOTE: See Troubleshooting section of the Appen-
dix for Flow Alarms information.

Connect Weather Sensor (optional)
EN
Remove the yellow jumper wire from the SENSOR
A
terminals on the controller.
NOTICE
Do not remove the yellow jumper wire unless connecting a rain sensor.
Connect both rain sensor wires to the SENSOR
B
terminals as shown.
WARNING
Do not route the rain sensor wires through the same opening as the
power wiring
NOTE: Rain Bird ESP-ME3 controllers are only
compatible with normally closed rain sensors.
NOTE: For wireless rain/freeze sensors, refer to
the sensor installation instructions.
Connect Power
WARNING
DO NOT plug in the transformer or connect external power until you
have completed and checked all wiring connections.
Installation with Pre-attached Cord
• Plug the attached power cord into a nearby 120VAC
electrical outlet.
