Rain Bird ESP-4Mi ESP Modular Indoor 4 Station Sprinkler Timer

Rain Bird® ESP-Modular Irrigation Controllers are indoor or outdoor controllers that can easily expand from 4 to 13 stations to meet your landscape needs. They have three independent programs and an array of features for maximum flexibility. They also incorporate Rain Bird's ESP Extra Simple Programming, making it easy to monitor and adjust watering schedules.

More Flexible
• Multiple programs give you the flexibility to accommodate the diverse watering needs of different plants and those areas of your lawn and garden that get more sun or shade, saving you water and money.
• Each program can have multiple start times, allowing you the flexibility to run programs several times a day for shorter lengths of time, helping you maintain a healthier lawn and garden.
• The modular design makes it easy to expand the controller’s capabilities to 13 stations should the watering needs of your landscape change in the future.
• The water budget feature allows you to easily increase or decrease watering schedules without reprogramming, so you don’t have to waste time at the controller.
• Four irrigation cycle modes for maximum flexibility and compliance to all major watering restrictions (Custom 7-day calendar, cyclic 1-31 day interval, and odd/even day calendar).
More Reliable
• Built in 5-year lithium battery keeps time, date and watering schedules intact during power outages, so relax and enjoy your landscape, worry-free.
• Superior surge protection — withstands nearly 3 times higher electrical surges than competitive controllers.
• Rain Bird quality construction and components.

Easier for You
• Easy programming: Rain Bird's easy to use Extra Simple Programming style with larger LCD display.
• Enhanced Diagnostic Feedback™ alerts you to conditions when watering is suspended due to an activated sensor, shorted stations or programming errors with a warning light and text message on the LCD.
