TRU Series Irrigation Controllers

TRU Control Over Your Landscape

Take control of your landscape with TRU series irrigation controllers from Rain Bird. Ideal for residential applications, TRU controllers are designed with aesthetics, usability and reliability in mind. Featuring a multi-function display and intuitive programming dial, these controllers offer the flexibility of three programs and four start times per program. Plus, they are upgradeable to WiFi-based remote monitoring and control with the addition of a LNK2 WiFi Module (sold separately). With TRU controllers, you can now have confidence that your landscape will remain healthy and beautiful year-round. That’s The Intelligent Use of Water™.

  • Greater scheduling flexibility – Keep your lawn healthy with program-based scheduling (A, B, C) and four start times per program for 12 total start times
  • Reduce water usage – Season adjust technology changes the watering duration (as a percent) for all programs simultaneously or to individual programs with associated with run times
  • Customizable watering options – By days of the week, odd or even calendar days, or cyclic every one to 30 days
  • Watering delay – Suspend watering for up to 14 days when it rains (applies only to stations set to obey rain sensor), watering automatically resumes after the set delay as elapsed
  • Professional features – Set an interstation delay, reset the controller to factory defaults, rain sensor bypass by station, save/restore programming and set a master valve by station
  • Advanced programming – Ability to set permanent days off per program to ensure watering never occurs on days when landscaping or maintenance crews are on site (for odd, even, or cyclic schedules)
  • Rugged design – Robust set screw terminals to accommodate AC power and valve connections, plus master valve/pump start relay and rain/rain freeze sensor; outdoor models come preinstalled in a contractor-grade case to withstand even the harshest environments
  • Manual watering options – For all stations, a single station, or an individual program
  • WiFi capable – Upgradeable to WiFi-based remote monitoring and control with the addition of a LNK2 WiFi Module (sold separately)
  • Meets EPA WaterSense criteria –  When paired with the LNK2 WiFi Module and a rain sensor (sold separately)
