The Rain Bird ESP-4M (Outdoor) - 4 Station Controller is a great mid to upper level irrigation control system for home and business landscapes. Its capability for expansion makes is perfect for new systems where all needs may not yet have been identified. Here are the best features and benefits of this controller, explained.

Modular Capacity

If you have a homeowner that can't quite make up their mind, or is constantly adding and re-arranging the landscape, the modular capacity of the ESP-4M controller saves a lot of time, cost and headaches. The controller comes equipped to handle four stations at a time, but can expand with the click of an additional module to accommodate 12 irrigation stations and an outdoor lighting station for automatic control.

Did We Mention the Outdoor Lighting Capacity?

What could be more convenient than managing outdoor lighting schedules along with the irrigation system. With this controller, everything can be maintained and timed in one convenient control panel.

Fuseless Circuit Breaker Keeps things Running

If one section of the irrigation systems becomes unable to function due to an electrical problem, the fuseless circuit breaker keeps the rest of the system running, isolating the problem area until it can be fixed. This feature is great for people who travel frequently-it gives peace of mind that the landscape will stay (mostly) watered, if part of the system goes down. There's nothing like avoiding total system failure during 100 degree summer days!

Contractor Default Program

Sometimes and overeager homeowner will try to tinker with the irrigation system, even if he or she doesn't have a clue what they should be changing or adding. For times when a client calls the irrigation maintenance firm and says "Help, I changed the program!" the Contractor default feature is wonderful. Rather than needing to re-program the entire system, the contractor can simply recall the original program from memory and make adjustments from there.

Advanced Sensors Conserve Water

Water restrictions are becoming more necessary and more highly regulated. Several options on the Rain Bird ESP-4M controller let homeowners modify or pause programs due to water restrictions. There is also a "permanent off day" feature as part of the programming capability to keep the system entirely shut down during mandatory no-water days.

Features for Easy Installation

Ease of use for the homeowner is great; however, these irrigation controllers are also easy to install and maintain. The cabinet is roomy, with plenty of space to maneuver within. Ribbon cables provide better visibility. You can "hot swap" or add additional modules without cutting power to the system, saving valuable time. A valve test system helps contractors see which valves are connected to which station for ease of programming. An added plus is the ability to program the controller using a 9 volt battery for power before installing the controller on the wall.

A Great Controller for Highly Varied Landscapes

Four different program cycles and the ability to serve so many stations makes the Rain Bird ESP-4M (Outdoor) - 4 Station Controller a top choice among landscape and irrigation professionals.
