About the Rainbird ESP4SMTEI

Other Smart Sprinkler Timers claim simplicity and precision; The RAINBIRD ESP4SMTEI F39400 INDOOR 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 can now expand from 4 up to 22 zones.

Product Features

  • Valentine's Day themed Decor
  • Expandable up to 22 zones using ESPSM6 Six Zone Expansion Modules or ESPSM3 Three Zone Expansion Modules.
  • Input Required: 120VAC +/- 10%
  • All ESP-SMTe models come with a heavy-duty adjustable bracket and 25 feet of 18-2 UV-rated non-burial wire for connection between the controller panel and the weather sensor pod. Up to 200 feet of appropriate wire may be spliced to extend range.
  • The ESP-SMTe 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.
  • The Rain Bird ESP-SMTe can grow with your landscape, easily expanding from 4 stations up to 22 stations with the addition of optional hot-swappable expansion modules.
  • Different plants have different watering requirements. That's why the ESP-SMTe 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 zone-specific data, the ESP-SMTe controller optimizes the irrigation schedule to promote lush, healthy plant material in each part of your yard, while substantially reducing water waste and runoff.
