About the Rainbird ESP4MEI Irrigation Controller, 120V Indoor 4 Station ESP Modular

Rain Bird ESP-Modular Controllers are simple to program, making it easy to monitor and adjust watering schedules based on your landscapes diverse watering needs. With a large, easy to read display and intuitive programming sequence, it is the most user-friendly irrigation/sprinkler controller in its class. The ESP Modular offers industry-leading surge protection, temperature tolerance and rugged construction. The spacious cabinet and terminal locations make installation and wire-up a snap.

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 controllers capabilities should the watering needs of your landscape change in the future. 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.
