2. Locate the keyhole slot on back of the controller unit and hang it securely on the mounting screw.
   
3. Open the front panel, and drive three additional screws through the open holes inside the controller and into the wall, as shown.
   

Connect Valves

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

Connect Master Valve (optional)

5. Connect a wire from the master valve to the MV (master valve) terminal on the Base Module. Then connect the remaining wire from the master valve to the field common wire, as shown.

Connect Pump Start Relay (optional)

1. Connect a wire from the PSR (pump start relay) 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.
2. To avoid the possibility of damage to the pump, 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

NOTE: Connection to pump and external power not shown. Refer to pump installation instructions.

Connect Flow Sensor (optional)

NOTE: Install the flow sensor in the field according to the manufacturer's instructions.

1. Run the flow sensor wires to the controller.
   
   Do not route valve wires through the same opening as power wires.
2. Connect both flow sensor wires to the Flow 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.
   

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 or to select SENS ON (sensor on) or SENS OFF (sensor off).

Sensor ON
Sensor OFF
Flow detected (flashing)

NOTE: When switching from Sensor OFF to Sensor 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 Appendix for Flow Alarms information.

Connect Weather Sensor (optional)

1. Remove the yellow jumper wire from the SENSOR terminals on the controller.
   
   NOTICE
   Do not remove the yellow jumper wire unless connecting a rain sensor.
   
2. Connect both rain sensor wires to the SENSOR terminals as shown.

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.

Weather Sensor Settings

Set the controller to obey or ignore a weather sensor.

When set to Sensor ON, automatic irrigation will be suspended if rainfall is detected. When set to Sensor OFF all stations will ignore the rain sensor.

Turn the dial to Weather Sensors.

• Press or to select SENS ON (sensor on) or SENS OFF (sensor off).

Sensor ON
Sensor OFF
Rain detected (flashing)

Connect Power

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.
  

Outdoor Installation with Direct Wiring

Electric shock can cause severe injury or death. Make sure power supply is turned OFF before connecting power wires.

POWER WIRING CONNECTIONS 120VAC
Black supply wire (hot) to the black transformer wire
White supply wire (neutral) to the white transformer wire
Green supply wire (ground) to the green transformer wire

1. Locate the transformer wiring compartment in the lower left corner of the controller unit. Use a screwdriver to remove the cover and expose the transformer connection wires.
2. Route the three external power source wires through the conduit opening at the bottom of the unit and into the wiring compartment.
3. Using the provided wire nuts, connect the external power source wires (two power and one ground) to the transformer connection wires inside the wiring compartment.
   
   Ground wire must be connected to provide electrical surge protection. Permanently mounted conduit shall be used for connecting main voltage to the controller
4. Verify that all wiring connections are secure, then replace the wiring compartment cover and secure it with the screw.

Station Expansion Modules

Optional Station Modules can be installed in the empty slots to the right of the Base Module to increase the station capacity up to 22 stations.

NOTE: 6-Station Modules are compatible with ESP-ME3 and ESP-Me. They are not backwards compatible with the ESP-M vintage controller.

NOTE: For ideal station sequencing, insert 3-Station module after inserting all 6-station modules. For more details see the Station Numbering section.

Install Modules

1. Verify the securing lever on the module is in the unlocked position (slide to the left).
2. Place the module under the desired slot between the plastic rails.
3. Push the module up into the slot until secure.
4. Slide the securing lever to the locked position (slide to the right).
   

REPEAT for additional modules.

NOTE: Modules can be installed or removed with OR without AC power connected. They are considered "hot-swappable".

NOTE: It take about 30 seconds for stations to become available for configuration after installing a new module.

Station Numbering

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.

• 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

1. Reinstall and reconnect the front panel.
2. Apply power to the controller and test the system.

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.

2. Press or to select a Station.
3. Press or to set the Run Time for the selected Station.
4. Press to set additional Station Run Times.

NOTE: Only assign Run Times in a Program for stations you want to water. If you do not want a specific station to run in a selected program then set the Run Time to zero.

NOTE: Rain Bird recommends that the maximum irrigation station cycle time be less than the time required for runoff to begin and that there be adequate soak time before the next irrigation cycle of that same station begins again.

Set Water Days

Custom Days of the Week

Set watering to occur on specific days of the week.

Turn the dial to Water Days

1. Press Program Select to choose the desired Program (if necessary).
2. Press or to set the selected (blinking) day as either ON or OFF, and to automatically move to the next day.
3. Press or at any time to move the cursor to the previous or next day.

NOTE: With Sunday selected, press the button to enter and activate Cyclic Watering (see the Advanced Programming section). If this is not desired, press the button to return to watering by Custom Days.

Program-Based Scheduling

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.

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!

Incorrect: Multiple Start Times set by mistake

Program Letter	Program Watering Time	Program Start Time	Station Number	Station Watering Duration
A	1st	8:00 AM	1	15 MIN
			2	15 MIN
			3	15 MIN
A	2nd	8:15 AM	1	15 MIN
			2	15 MIN
			3	15 MIN
A	3rd	8:30 AM	1	15 MIN
			2	15 MIN
			3	15 MIN

Correct: Only one Start Time

Appendix

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)

Error	ALARM LED	Error Message On Display
No Start Times are set	BLINK	NO START TIMES
No Run Times are set	BLINK	NO RUN TIMES
No Water Days are set	BLINK	NO WATER DAYS

The error will go away when the station is successfully run after condition is corrected.

NOTE: The dial must be in the AUTO position for an ALARM message to appear on the display.

Electrical Errors (non-blinking LED)

Error	ALARM LED	Error Message On Display
Master Valve short	SOLID	MASTER VALVE SHORTED OR HIGH CURRENT
Station short	SOLID	STATION "X" WIRE SHORTED

When an electrical error is detected, irrigation for the affected station is cancelled and watering advances to the next operable station in the program.
The controller will attempt to water the affected station again at the next scheduled watering. Completion of a successful watering will clear the error condition associated with that station.

Flow Alarms

Error	ALARM LED	Error Message On Display
Flow Sensor - High Flow Condition	Solid	HIGH FLOW ALARM STATION "X"
Flow Sensor - Low Flow Condition	Solid	LOW FLOW ALARM STATION "X"

When a flow sensor is in use the ESP-ME3 monitors for High Flow of 130% above regular learned flow. This percent limit can be adjusted in the Rain Bird App when used with LNK™ 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.
Low Flow conditions are also monitored. The limit for Low Flow is 70% below the learned flow unless changed in the Rain Bird App. A Low Flow alarm is shown at the controller display and the red alarm LED comes on.
To clear the alarm press the "Hold to Start" right arrow button during the alarm message.

NOTE: Turning the flow sensor feature off and then back on will cause the controller to learn new flow levels and ignore previous error conditions.

NOTE: If the flow sensor measures flow when the controller is not scheduled for watering, a "HIGH FLOW ZONE" alarm is shown on 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.

Watering Issues

Problem	Possible Cause	Possible Solution
Display shows a program is active, but system isn't watering.	Water source not supplying water.	Verify there is no disruption to the main water line and that all other water supply lines are open and functioning properly.
	Wiring is loose or not properly connected.	Check that field wiring and master valve or pump start relay wiring is securely connected at the controller and in the field.
	Field wires are corroded or damaged.	Check field wiring for damage and replace if necessary. Check wiring connections and replace with watertight splice connectors if needed.
	Loss of AC power.	When there is a power loss and a 9 volt battery is installed, the system does not irrigate but programs show as remaining active.
NO AC message on display.	No Power detected.	Check circuit breaker and that unit is plugged into socket or properly connected to power source.
	Controller may be plugged into a GFCI outlet or an outlet that is wired to a GFCI outlet.	Check power to the outlet or reset the circuit breaker.
It just rained and the alarm light is not illuminated, why?	This is normal operation. The ESP-ME3 does not consider the interruption of irrigation due to rainfall as an alarm condition.	This is normal operation.
Programmed schedules do not start.	Connected rain sensor may be activated.	Set Rain Sensor to Sensor OFF to ignore the rain sensor. If watering resumes, the sensor is operating properly and no further correction is needed.
	Connected rain sensor may not be operating properly.	Let the rain sensor dry out, or disconnect it from the controller terminal strip and replace it with a jumper wire connecting the two SENS terminals, or set to Sensor OFF.
	If no rain sensor is connected, the jumper wire connecting the two SENS terminals on the terminal strip may be missing or damaged.	Move dial position to Weather Sensors and set to Sensor OFF.
Too much irrigation	Multiple Start Times in the same program.	Separate start times are not required for each valve. A program only requires single start time in order to run all stations in that program.
	Multiple programs are running at the same time.	Review programming to assure that the same Station is not active in multiple Programs.
	Valve is malfunctioning.	Check to see if the ALARM light on the controller is lit solid, then repair or replace the valve if necessary.
	Seasonal Adjust setting is too high.	Set Seasonal Adjust to 100%.

Electrical Issues (solid LED illuminated)

Problem	Possible Cause	Possible Solution
Display is blank or frozen, the controller will not accept programming or is operating abnormally.	Power not reaching the controller.	Verify the main AC power supply is securely plugged in or connected and working properly.
	Controller needs to be reset.	Press the Reset Button. For details see "Reset Button" section.
	An electrical surge may have interfered with the controller's electronics.	Unplug the controller for 2 minutes, then plug it back in. If there is no permanent damage, the controller should accept programming and resume normal operation.
Automatic error detection indicates a problem by ALARM LED and an error message on display.	Short circuit or overload condition in valve, master valve or pump start relay wiring.	Identify and repair the fault in the wiring. Refer to compatible pump start relays. For details see "Connect Pump Start Relay" section.
LED is flashing or solidly illuminated but I see no message on the LCD.	Dial not in AUTO RUN position.	Turn dial to AUTO RUN position. Push Reset button or power cycle the controller.
