RAIN BIRD ESP-SMT SMART SERIES CONTROLLERS / TIMERS:

The Rain Bird ESP-SMT Smart Control System delivers simplicity and precision.

4 Station modular Smart Controller plus weather sensor, automatically adjusts watering times for each zone based on temperature, effective rainfall and plant/soil type to reduce water use by 30-70%. The Rain Bird ESP-SMT Control System expands up to 13 stations with plug-in expansion modules (ESP-SM3 - 3 Zone Expansion Module). Indoor and Outdoor models available. The upgrade kit (front panel and sensor only) also available to convert existing ESP-Modular controllers into ESP-SMT Smart Controllers.

• The proven accuracy of weather-based scheduling
  By self-adjusting to the landscape's changing water needs, it eliminates the programming errors and guesswork of a time-based system.

• Instant rainfall shut-off and useable measurement The ESP-SMT not only suspends irrigation, it measures instantaneous rainfall amounts, determines the effective rainfall and calculates exactly how much to adjust your watering schedule to prevent over-watering and under-watering.

• Zone-specific water calculations
  The ESP-SMT customizes each zone's irrigation schedule. It factors in location, soil type, landscape slope, plant type/density, sun exposure, sprinkler type and root-depth requirements. Based on this zone-specific data, the ESP-SMT controller optimizes the irrigation schedule to promote lush, healthy plant material in each part of your yard, while substantially reducing water waste and runoff.

• Expandable modular design
  The Rain Bird ESP-SMT can grow with your landscape, easily expanding from 4 stations up to 13 stations with the addition of optional hot-swappable expansion modules. Compatible module: ESP-SM3 3 station expansion module
