Rain Bird® ESP Modular Irrigation Controllers
Maximize Your Productivity

ESP-4M Outdoor Controller

The ESP Modular Irrigation Controller is designed to maximize your productivity by saving you time and money. Easily expand from a 4 station base model to 13 stations with 3 station hot-swappable modules, which can be added without powering down the controller.

Another example of Rain Bird's legendary reliability, the ESP Modular offers industry-leading surge protection, temperature tolerance and rugged construction. It improves upon Rain Bird's already easy-to-use ESP style of programming with a large, easy to read display and intuitive programming sequence, making this the most user-friendly irrigation controller in its class. The spacious cabinet and terminal locations make installation and wire-up a snap. And features like the Contractor Default™ program make service calls more efficient and earn you more money by taking less time! The Rain Bird ESP Modular: Maximizing your Productivity.

More Reliable:

  • NEW! 5-year lithium battery (Rain Bird Exclusive) and non-volatile memory, keeps time, date and program schedule in case of power outage.
  • Superior surge protection — withstands nearly 3 times higher electrical surges than competitive controllers.
  • Rain Bird quality construction and components.
  • Fuseless, diagnostic circuit breaker identifies a station with valve or wiring problems and continues to water operable stations.

More Flexible:

  • Easily expandable from a four station base model to 13 stations with the additon of 3-station modules at installation or in the future. Modules can also be installed in any available slot.
  • NEW! Longer station run times add more flexibility for special applications such as drip.
  • NEW! Programmable master valve allows pump to operate only as needed, resulting in greater flexibility in controlling the water source.
  • NEW! Programmable Delay Between Stations allows additional time between zones for water well recovery or slow closing valves.
  • Auxiliary Station™ can be set to bypass an active sensor to allow watering even if the other stations are disabled or can be set as a normal station.
  • 365-day calendar with leap year intelligence means that you can set an “Odd” or “Even” day watering schedule and not worry about changing the date on leap years.
  • 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).

Easier for You:

  • Contractor Default Program (Rain Bird Exclusive!) allows retrieval of a default program you save in to memory. Easily replace a schedule that has been altered by the homeowner in seconds.
  • Hot swappable modules allow adding more stations without powering down the controller.
  • NEW! Improved Ribbon Cable provides better visibility and ease of connection.
  • Larger cabinet space provides more room for wiring installation.
  • “Valve Test Terminal” allows the installer to test the valve wires during installation to determine the valve that each wire is connected to.
