HSC LED Light codes
The LED lights on the HSC illuminate with distinct colors and flashing patterns to let you know where or when an Alert, Caution, or irrigation is taking place. These can be helpful when troubleshooting the controller.
Colors #
Colors will inform users of the following conditions:
| Red/Alert: | Yellow/Caution: | Green: |
| Shows a fault, disconnection, | Delay, or other warning. | Watering, communication |
| no water flow, or other | connected, or other | |
| problem that requires | operations performing as | |
| attention. | expected. |
Other colors are defined in the charts below.
Patterns #
LEDs may flash, fade in and out slowly, or be solid:
| Flashing: | Fading in and out: | Solid: |
| Indicates an Alert. | Communication is connecting, or the controller is in a preparatory state. | Communication connected, or a normal operating condition. Solid red indicates a problem. |
Control Panel LED’s #
On the HSC’s control panel, there are three LEDs:
| Controller Status: | Comm Status: | Cellular: |
| Indicates what the controller is doing. | Shows the controller’s communication method and activities. | Cellular connection and activity. |
Reference these charts for specifics about what the HSC controller is doing.
| COLOR | PATTERN | MEANING |
| RED | FLASHING | Leak, Station Fault, Pump Fault, No Flow, High Flow |
| YELLOW | FLASHING | Weather Delay, Rain Sensor Delay when the controller is not watering |
| YELLOW | SOLID | Low Flow, Rain Sensor Delay during scheduled irrigation |
| GREEN | SOLID | Scheduled Watering Event, Manual Watering Event, Rain Sensor Delay during manual watering |
Module LEDs #
The LEDs on the Multi-wire modules can also help you understand what is happening with specific zones and troubleshoot issues with the controller. Colors and pattern are in the chart below.
| COLOR | PATTERN | MEANING |
| RED | SOLID | Zone Fault, or No Flow (if a Flow Sensor is installed) |
| YELLOW | SOLID | Rain Sensor Delay |
| GREEN | SOLID | Scheduled Watering or Manual Watering |
Red lights will stay on to let you know where a problem exists. Red will clear if the condition is fixed – during the next watering cycle.
