Top Benefits of the Rain Bird Esp-4tm 4 Station Indoor Controller

Having an irrigation control unit that is easy to program and use is essential for the home landscape. The Rain Bird ESP-4TM 4 station indoor controller is the perfect control panel for lawns and gardens around homes and small businesses. Here are the main reasons why this control panel is favored by so many.
Slim Design is Unobtrusive
This indoor irrigation control panel is perfect for home landscapes, as it can be installed indoors in a location that is accessible, clean and easy to find. The narrow cabinet for the controls is perfect for installation in a garage or shed.
Dual Program Capacity Ensures Plant Health
Turfgrass and flower beds have different water requirements, as do areas of the lawn in sun and shade. This four station controller has built in capacity to save two different programs so that areas of the lawn with different growth conditions can be watered appropriately.
Protection from the Elements
In addition to the comfort of programming and operating the control panel from inside the house, the panel itself contains several innovations that help protect it from damage. Its internal components are essentially surge-resistant. That benefits the user in two ways: it keeps programs from being wiped out resulting in the need for re-programming. More importantly, the surge protection helps to keep adverse effects away from the irrigation lines, which are even more difficult to fix.
User-Friendly Interface
A fully automated irrigation system is no good if the user isn't comfortable working with it. The Rain Bird ESP-4TM irrigation controls are easy to program, with an intuitive, self-prompting screen. A landscape contractor can teach his or her clients how to program the system fairly quickly and easily.
Flexibility for Efficiency
With more water restrictions in place yearly, it is important to have flexibility in an irrigation system control panel. This irrigation control has a few water-saving features. First is the dual program capacity so that the right amount of water can be delivered to the proper zones. The Water Budget feature allows users to change the frequency and amount of water put out to comply with local water regulations.
Capacity Suitable for Small Landscapes
The four station control is appropriate for home landscapes. Control panels with six and eight station capacities are best for larger, more diverse landscapes and business landscapes. Unfortunately, this control panel is not modular. In order to add capacity, an additional panel must be installed. The panel and circuitry can handle one 24VAC, 7VA solenoid valve per station, in addition to a main valve for the entire system, or everything on the control panel.
Backup Program for Extended Power Outage
In the event of an extended power outage, the system will re-start when power is available and run 10 minutes per cycle beginning 8 hours after power resumes - once per day for the 7-day custom cycle or on the first day of the 2-, 3- or 5-day fixed cycle. This way, even if the programs are erased, the lawn or garden will not go completely without water until the system can be re-programmed.
For small landscapes, the quality and usability of the Rain Bird ESP-4TM 4 Station Indoor Controller is hard to beat.
