HRC 100 Programing

The HRC 100 C provides the flexibility of using 3 independent programs (A, B, and/or C). A program is where you store all of your sprinkler settings. It consists of a group of stations set to specific start times and run times. Multiple programs allow you to run different valves on different days with different run
times. While many applications only require one program (A), using multiple programs can be useful for drip areas, newly planted lawns, or rotary sprinkler stations. Using programs to group stations with similar water needs will maximize irrigation efficiency.

To clear any previous programming to clear factory programming Press the [RESET] button with a paperclip, pen, or other small objects.

  • When a start time is set before the previous program has been completed, that start time will be “stacked” or delayed and will start upon completion of the previous program.

  • If the controller is scheduled to run in the next 24 hours then the display will toggle between the current time and the next scheduled start time

NOTES: #

If your program is lost, the factory-installed fail-safe program will turn on each station every day for 10 minutes

Your prior programming will not be disturbed unless altered. Always be aware of the program you are in (A, B, or C) when you are making changes.

Reviewing and Changing Your Program #
