Outstanding Results:

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 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.
The water budget feature allows you to easily increase or decrease watering schedules without re-programming, so you don't have to waste time at the controller.
Built in 5-year lithium battery keeps time, date and watering schedules intact during power outages, so relax and enjoy your landscape, worry-free.
