Rain Bird^® ESP-SMT Smart Modular Irrigation Timers
A control system as simple as it is Smart.

ESP-SMT4 4-Station Outdoor Smart Controller with Weather Sensor.
 

Other Smart Controllers claim simplicity and precision; the Rain Bird® ESP-SMT Smart Control System delivers. Combining the proven simplicity of the Extra Simple Programming (ESP) controller family with the accuracy of weather-based control, this innovative system is engineered to save valuable time, money and water.

The ease and speed with which you can program this controller is remarkable. Simply input a few key specifics, such as your zip code, allowed watering days and the plant/soil type for each zone; the ESP-SMT does the rest. Your irrigation system waters only when the landscape requires it. And you save 30-70% in water.

The ESP-SMT maximizes water efficiency by factoring in everything from soil type to the slope of your lawn to the amount of sun exposure different areas receive. All of these details are calculated for every zone of your automatic sprinkler system to help you maintain a lush, healthy lawn and landscape.

Features:

	Quick and Easy Programming Simply input a few key specifics like zip code and allowed watering days; the ESP-SMT does the rest. Your installation time is cut dramatically. Your site's irrigation system waters only when the landscape requires it. And your customers save up to 30-70 percent in water.
	Instant rainfall shut-off and useable measurement Almost all Smart Controllers stop watering when it rains; but only the ESP-SMT suspends irrigation and measures useable rainfall, determining its effectiveness and calculating a replacement value. The result is virtually no under- or over-watering.
	The proven accuracy of weather-based scheduling The ESP-SMT is a simpler, more affordable version of the weather-based controllers Rain Bird began pioneering for golf courses over 25 years ago. Now you can offer homeowners the same water savings that larger sites have been enjoying for years.
	Zone-specific water calculations The ESP-SMT automatically customizes each zone's irrigation schedule to its unique watering requirements. Just enter a few key details such as soil type and sun exposure. The ESP-SMT's controller engine optimizes scheduling to promote plant health and eliminate wasted water.
