ESP-Site Satellite Series Controllers

12, 24, 40 Station Field Satellite

The ESP-Site Satellite controller is the most versatile satellite controller yet. This controller combines the capabilities of the Cluster Control Unit (CCU) with all the power of an ESP-SAT controller. Powerful enough for large sites yet flexible for smaller applications.




  • Combines the function of a Cluster Control Unit (CCU) with an ESP-SAT controller.
  • Stores and executes schedule instructions from the central computer
  • Operates up to 40 stations.
  • Communicates with central computer via telephone, hardwire, radio or fiber-optic cable.
  • Available in wall mount, stainless steel pedestal, retrofit kit for existing stainless steel pedestals or upgrade kit for existing ESP-MC or ESP-SAT controllers.
  • Four programs with eight start times each allow mixed irrigation applications in a single controller.
  • Two master valve terminals, one programmable by station, provide better control.
  • 365-day calendar with leap year intelligence for one-time date and time setting.
  • Event day off option to set any day of the month as a non-watering day for all programs.
  • Programmable rain delay enables system to stay off for specified period with auto-restart.
  • Water budget by program provides adjustments from 0-300% in 1% increments.
  • Cycle+Soak™ by station allows total irrigation run time to be split into usable cycles, minimizing runoff.
  • Sensor override switch with LED to indicate when irrigation is suspended.
  • Non-volatile, 100-year memory holds program, date, and time during power outages.
  • Automatic fault indication identifies electrical shorts, skips shorted stations, and continues watering remaining program.
  • Quick-connect terminal strip speeds installation.
  • 2 sensor inputs.
  • Universal remote ready: pre-installed connectors for addition of remote products.
  • Battery-programmable controller allows for programming prior to installation.
  • Three-year trade warranty.
