ESP-LXD Series Two-Wire Decoder Controller

Your foundation for simple, decoder-based control.

Rain Bird ESP-LXD Two-Wire Decoder Controller

Building on the success of the popular ESP-LXM commercial controller, Rain Bird is pleased to introduce the new ESP-LXD controller. The ESP-LXD controller has been designed to maintain the look, feel and ease of programming of the ESP-LXM controller but with an interface to a two-wire path for decoder-based irrigation. The ESP-LXD controller can manage up to 50 stations but can easily be expanded for use with up to 200 stations. Flow Management is also built in to every ESP-LXD controller.


How Two Wire Control Works

Your ESP-LXD controller is linked to decoders in the field by a two-wire path. This path carries voltage and information.


To allow watering, the ESP-LXD sends out a unique signal to one of the decoders on the two-wire path.


The signal instructs that decoder to open the valve.


Because the signal only applies to the decoder and valve at that specific address, no other decoder accepts the instructions.


Easy to Use

The ESP-LXD Controller utilizes the Rain Bird® ESP Extra Simple Programming user interface. The dial, switches, and buttons interface, which Rain Bird first introduced in the 1980s, is easy to learn and use and has become a standard controller interface for the irrigation industry. The large LCD display incorporates softkey text labels for the button functions rather than dedicated buttons.

Easy to Install

The ESP-LXD Controller has a spacious case and eight lugs for up to four two-wire paths (which are all managed as a single two-wire path) making installation fast and easy. Multiple size wiring knockouts are provided on the bottom and back side of the case to adapt to a wide variety of wiring applications. The door and front panel are removable so the case can be easily mounted to the wall.

Advanced Features

From Cycle+Soak™ to Contractor Default Program™, the ESP-LXD offers innovative features proven to cut installation expenses, troubleshooting time and water use.

Unprecedented Flexibility

A modular design makes the ESP-LXD the perfect fit for a range of large residential and commercial projects—from the straightforward to the most complex.

200-Station Capacity

The ESP-LXD offers the ability to expand from 50 stations to up to 200 stations. So you can handle sites large or small, while stocking fewer controllers and components.

Built-In Flow Management

FloManager® ensures you don’t overtax your water supply, while Flo-Watch™ quickly identifies and isolates high or low flow situations, such as mainline breaks.

Smart Approved Watermark

Rain Bird’s ESP- LXD controller has received the Smart Approved Watermark. Established in Australia and recognized worldwide, this elite designation identifies products and services that help reduce water use.

Station Module

Included with every ESP-LXD is the ESP-LXD-M50 module, a “double-wide” module which snaps onto two adjacent mounts on the controller backplane. The ESP-LXD-M50 module includes the lugs for attachment of the two-wire path cables. Built in to every ESP-LXD module is Rain Bird’s Flow Smart software for flow management – simply attach one to five SD-210 sensor decoders and flow meters (not included) to the two-wire path, and the controller will do the rest.


The ESP-LXD Controller has an optional LXMM Metal Wall-Mount Case and LXMM-PED Metal Pedestal. The ESP-LXD standard plastic case field installs into the LXMM and can be wall-mounted or attached to the LXMM-PED for free-standing controller applications. The LXMM and LXMM-PED use powder-coated steel for years of rust-free operation. The pedestals are also available in stainless steel, LXMMSS & LXMMSSPED.

PBC-LXD Cartridge

A new optional offering for the ESP-LXD controller is the PBC Program Backup Cartridge. This multi-functional cartridge installs into the cartridge bay in the back of the controller front panel. The PBC has two key features to simplify installation and management of one or more ESP-LXD controllers:

Backup and Restore. The PBC allows eight full backups of all programming on an ESP-LXD controller. Use it on multiple occasions for a single controller or once for several different controllers. Once programs are backed up to the PBC, they can quickly and easily be restored, and the PBC is designed for convenient travel to take to controller sites.

Decoder Address Entry. With the PBC, you’ll never have to manually enter decoder addresses again. Simply attach a barcode scanning pen (sold separately) and scan the peel-off barcode labels from the Programming Chart included with the controller. Your decoder addresses are entered for you automatically within minutes.

FD Series 2-Wire Decoders

Rain Bird® Field Decoders provide easy, cost-effective installation and expansion for the ESP-LXD Decoder Controller. Choose from five models for the level of control that’s right for you. Learn more about FD Series 2-Wire Decoders.

DB Series Waterproof Wire Connectors

Rain Bird's DB Series wire connectors are quick to install and provide reliable moisture sealing for controller and valve electrical connections you can count on. Learn more about DB Series Wire Connectors

Flow Sensors

Combine the ESP-LXD with Rain Bird® Flow Sensors for precise and accurate flow monitoring (Flow Smart Module also required). Choose from a variety of sensor sizes, operating ranges and types for the solution that best meets your needs. Learn more about Flow Sensors.

Rain/Freeze Sensors

Add a Rain Bird® Rain/Freeze Sensor to your ESP-LXD to save time, improve system performance and can enhance your reputation as a water management expert. Learn more about Rain/Freeze Sensors.


The Rain Bird® Anemometer can add yet another weather-based component to your ESP-LXD by providing site-specific wind speed measurements. The controller can interrupt irrigation when wind velocity reaches a programmed set point. Learn more about the Rain Bird® Anemometer.

Programming Recommendation

Rain Bird recommends that the maximum irrigation zone 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 zone begins again.

Why does the controller report that the 2-Wire Path is Off?

Turn dial to Off.  Select 2-Wire Path button and press On.

When I program station run times, why does the screen say “No Decoder Address”?

Turn dial to Setup Wizards and select Station Setup.  Complete the setup wizard, entering a decoder address for each station.

One of my four 2-wire paths has been cut/damaged. How do I continue using the valves on my other 2-wire paths while I fix the cut/damaged 2-wire path?

Disconnect the damaged 2-wire path from the decoder module terminal strip and leave the other 2-wire paths connected.

The controller reports the Short Detect Mode is on due to a short on one of my 2-wire paths. How do I figure out which of my 2-wire paths has the short?

Disconnect all the 2-wire paths. The controller will exit the Short Finding Mode.  Reconnect one 2-wire path at a time and monitor the controller display. When you add the 2-wire path that is shorted, the controller will automatically turn on the Short Finding Mode.

Why is the lower light on a decoder module(s) not illuminated?

The Decoder Module has detected a 2-wire path short and is in Short-Finding Mode.  Turn dial to Test All Stations / Check System and select 2-Wire Diagnostics.

The controller reports that a weather sensor is preventing or pausing watering. How can I determine the status of my weather sensors?

Turn dial to Test All Stations / Check System. Select Weather Sensor Status to see the status of all Weather Sensors.

I need to repair a valve on my system but I have a Normally Open Master Valve. How do I turn of the Master Valve?

Turn dial to Off.  MV Off follow directions to manually close the Normally Open Master Valve.

Why are valves operating on the wrong dates/times?

- Date/time is not set correctly. Turn dial to Set Current Date, Set Current Time and set current date/time.
- Unknown Start Days/Times have been entered. Turn dial to Test All Stations / Check System and select Program Review. Review the controller programming and remove any unwanted Start Days/Times.
- A Program Water Window has delayed watering. Turn dial to Test All Stations / Check System and select Program Review. Review Programs. Change Program Water Window to allow all full program run time.

Why can't the controller turn on the valve(s)?

- Controller may not be wired correctly to the decoder or the decoder to the valve. Turn dial to Test All Stations / Check System and select 2-Wire Diagnostics to test decoders, valve wires and solenoid.
- 2-Wire Path may be damaged/disconnected. Turn dial to Test All Stations / Check System and select 2-Wire Diagnostics to test decoders.
