Rain Bird ESP-ME to ESP-ME3 WiFi Conversion Kit Instruction Manual

1. Introduction

This instruction manual provides comprehensive guidance for upgrading your existing Rain Bird ESP-ME irrigation controller to the advanced ESP-ME3 model, which includes the LNK WiFi Module for smart irrigation management. This kit is designed to simplify the upgrade process, allowing you to enhance your irrigation system's capabilities without extensive re-wiring.

The ESP-ME3 controller, when paired with the LNK WiFi module, offers enhanced features such as faster app speeds, advanced flow sensing, Cycle+Soak programming for efficient watering, and improved manual watering options. Its larger, backlit display and simplified dial-based control panel ensure ease of use and programming.

2. Setup and Installation

2.1. Safety Precautions

Always disconnect power to the existing controller before beginning any installation or wiring.
Ensure all wiring connections are secure to prevent electrical hazards.
Consult a qualified electrician if you are unsure about any electrical connections.

2.2. Preparing for Installation

Before removing your old ESP-ME controller, it is crucial to document your existing wiring. Take a clear photograph of all wiring connections to the terminal block. This will serve as a reference for connecting the new ESP-ME3 backplane assembly.

2.3. Replacing the Controller Faceplate and Backplane

Disconnect Power: Turn off the main power supply to your existing ESP-ME controller.
Remove Old Faceplate: Carefully detach the old ESP-ME faceplate.
Remove Old Backplane: The conversion kit includes a new larger ribbon cable and backplane assembly. The old panel will not plug into the new ribbon cable due to different pin configurations. Remove the existing backplane assembly by unscrewing the 4 screws that secure it.
Install New Backplane: Position the new backplane assembly and secure it with the 4 screws. The station wiring does not need to be removed from the modules; simply unlock the modules and slide them downwards.
Connect Ribbon Cable: Connect the new larger ribbon cable from the new backplane to the ESP-ME3 faceplate.
Connect Wiring: Using your reference photo, connect the station wires to the corresponding terminals on the new ESP-ME3 backplane. Connect the common wire (usually white) to the terminal marked 'C'.
Install LNK WiFi Module: Insert the LNK WiFi Module into the designated accessory port on the controller.

4. Maintenance

Regular Inspection: Periodically check the controller and wiring for any signs of damage or wear.
Cleanliness: Keep the controller's display and buttons clean and free from dust or debris.
Sprinkler Head Check: Occasionally run a manual watering cycle and visually inspect all sprinkler heads to ensure they are functioning correctly and irrigating as intended. This helps identify any damaged heads or areas not receiving adequate water.
Software Updates: Ensure your Rain Bird mobile app and controller firmware (if applicable) are up-to-date for optimal performance and access to new features.

5. Troubleshooting

Controller Not Powering On:
- Check the power connection to the outlet.
- Ensure the power outlet is functional.
WiFi Connectivity Issues:
- Verify your WiFi network is operating on the 2.4 GHz band. The LNK WiFi Module is not compatible with 5 GHz networks.
- Check the signal strength at the controller's location using a mobile device. If the signal is weak, consider moving your router or adding a WiFi signal booster.
- Ensure the LNK WiFi Module is properly inserted into the accessory port.
Sprinklers Not Running:
- Check if the controller is set to 'OFF' or if a temporary rain delay is active.
- Verify that the watering schedule is correctly programmed (start times, run times, water days).
- Inspect wiring connections to ensure they are secure.
- If a rain/freeze sensor is installed, ensure it is not preventing irrigation.
App Not Responding:
- Restart the Rain Bird app.
- Check your mobile device's internet connection.
- Ensure the LNK WiFi Module has a stable connection to your home WiFi network.
