I2CF-800 Series Controllers include built-in flow monitoring capabilities and two sensor inputs: one dedicated to a flow sensor connection and the other for a Clik/Solar Sync sensor. These sensor inputs are wired separately across the Common terminal on the Power Module, designated by a flow icon and a weather icon.
All flow monitoring is enabled and configured at the Controller facepack.
IMPORTANT: All stations that will be flow monitored must have a run time set prior to the flow learning process. Any stations without a run time will not be included in the calibration.

- Hold the + button and turn the dial to Pump, then release the + button to access the Flow Setup menu.
- Use + and – buttons to enable flow monitoring, and select units of measure (gallons/min or liters/min)
- Press the right arrow button to configure the flow sensor.
- If the sensor is frequency/velocity-based (i.e. Hunter HFS), input the manufacturer-specified K-Factor value.
- Use the + and – buttons to input the values.
- Press the right arrow button to input the Offset value (if applicable).
- Use the + and – buttons to edit the value.
The calibration numbers are important when using Hunter flow sensors to ensure the best flow results possible. Please reference the charts before using Hunter Flow Sensors.
