2. Select Change Flow Settings set the Sensor Type to Rain Bird FG100.
   NOTE: You may also input the FG100’s specific K-Factor and offset by setting the sensor type to other.
3. Select Learn Flow from the Flow Sensor Settings screen, the controller will begin to Learn Flow. It will run each station for 3-4 minutes to set the expected station flow.

View and Edit Learned Flow Rates

If you have learned flow rates then you will be able to view and edit them on the Change Flow Settings screen.

Adjust Alarm Threshold

You can change the Alarm Threshold from the Change Flow Settings screen. The default is 130% of learned flow and 70% of learned flow.

Set alarm action

• Alarm Only – Regular irrigation will continue for all zones
• Alarm & Skip Problem Zone (Default) – Irrigation will be suspended for the problem zone (station)
• Alarm & Skip All Zones – Irrigation will be suspended for all zones (stations)

Adjust Settling Time

Settling Time is the time (from 1-10 minutes) that a flow rate must remain at or above the High Flow Threshold or below the Low Flow Threshold before the controller will issue an alarm or take action.

Manual K-Factor Offset Input

You may choose to input the K-Factor and Offset values manually. This can be done by setting the Sensor Type to Other.
