Rain Bird ESP-TM2 Series Irrigation Controller

The Rain Bird ESP-TM2 Series is a professional-grade irrigation controller engineered for simple and reliable residential landscape management. Featuring the “Extra Simple Programming” interface, this controller is available in multiple station configurations to suit diverse yard requirements. It offers a flexible scheduling architecture with 3 independent programs and up to 4 start times available per program, allowing for precise tailoring of watering cycles. A key technical advantage of the ESP-TM2 is its modular “Smart” capability; by installing the LNK WiFi Module (sold separately), users can upgrade the unit to a WiFi-enabled device with EPA WaterSense certification, enabling remote access and weather-based adjustments through the Rain Bird mobile app.

Operational specifications include station timing from 1 minute to 6 hours and a seasonal adjustment range of 5% to 200% for efficient water conservation. The hardware features a non-volatile memory that permanently saves programming during power outages, while an internal 10-year lithium battery maintains the controller’s time and date accuracy. Built-in maintenance features include “Contractor Default” for saving and restoring custom schedules, automatic short-circuit detection with station-specific alarms, and a master valve/pump start relay. Designed for long-term outdoor or indoor durability, the ESP-TM2 includes a sensor bypass for individual stations and an adjustable delay between stations to allow for well recovery. This series remains a standard for contractors seeking a robust, user-friendly system that balances manual control with advanced digital connectivity.
