Rain Bird ESP-ME3 modular controller and accessories

The ESP-ME3 is a modular 230 V irrigation controller for residential and light-commercial systems. The controller starts with four stations and can be expanded to 22 stations with compatible 3- and 6-station modules.

Controller features

• Four independent programmes with six start times per programme.
• Station run times from 1 minute to 6 hours.
• Seasonal adjustment from 5% to 200%.
• Built-in flow-sensor input, high-flow alarm and station shut-down when configured with a compatible flow sensor.
• Short-circuit detection with an LED alert.
• Master-valve or pump-start relay output, rain-sensor input and per-station rain-sensor bypass.
• Modules can be added without removing or powering down the controller.
• Optional LNK2 module adds Rain Bird app control and weather-based adjustment.

Choose the correct option

• ESP-ME3 controller: four-station base controller.
• 3-station module: adds three stations to a compatible ESP-ME3.
• 6-station module: adds six stations to a compatible ESP-ME3.
• LNK2 WiFi module: adds compatible app and internet functions; it is not a controller by itself.

Selection note: Expansion modules and the LNK2 are accessories and cannot operate alone. Plan the module combination carefully because the controller supports a maximum of 22 stations.

On-page guidance: The product gallery shows ESP-ME3 station-expansion combinations and manufacturer module-fitting steps. Expansion modules use fixed station numbers, so 3-station modules can leave numbering gaps. The fitting image covers station modules only; follow the manufacturer instructions for the supplied 230 V controller for mains installation. Isolate the mains supply before connecting power wiring and keep field wiring separate from mains wiring.
