With large turn dial programming and the option to upgrade to the Hydrawise app for remote programming, Hunter’s X2 controller is a complimentary combo of old and new. Allowing water schedules to be programmed with ease, there are a number of extra features available to be set according to the yards specific needs. In addition, the X2 is compatible with many different sensors to improve the overall efficiency of a sprinkler system. Acting as the “brain” of a sprinkler system, a controller lets the system know when to turn on in accordance with the scheduled programs. It sends electric signals to the valves letting them know to “OPEN THE GATE!!” X2 controllers have a warranty life of 2 years.
