Setup and Installation
Proper installation is crucial for accurate operation. Follow these steps:
- Component Placement: Properly install the flow sensor and solenoid valve in the water line. Ensure the flow sensor and solenoid valve direction aligns with the water flow direction. An arrow on the flow sensor indicates the correct flow path.
- Wiring: Connect the flow sensor, solenoid valve, and temperature sensor to the DFC15 controller according to the wiring diagram. Connect the 12VDC power adapter to the controller.
- Initial Settings: Before operation, set the K value, quantitative value, and maximum alarm value on the DFC15 controller. Refer to the operating instructions for details on setting these parameters.
- Environmental Considerations: Avoid exposing the controller to water or excessive humidity to prevent damage.

Operating Instructions
Once the system is installed and initial settings are configured, follow these steps for operation:
- Start Operation: Press the RUN/STOP button to initiate the control process. The controller will begin displaying the current flow volume, current flow rate, and the faucet animation will start.
- Quantitative Control: The controller will automatically turn off the solenoid valve when the total flow reaches the pre-set quantitative value. At this point, the total value display will stop, the faucet animation will cease, and the flow rate will return to zero.
- Repeat Operation: To repeat the same job, press the RUN/STOP button again.

Maintenance
To ensure the longevity and proper functioning of your DIGITEN DFC15 Water Flow Control System, observe the following maintenance guidelines:
- Protect the Controller: Always avoid direct contact of the controller with water or other liquids. Ensure it is installed in a dry environment.
- Regular Inspection: Periodically check all connections for tightness and signs of wear.
- Cleaning: Clean the exterior of the controller with a soft, dry cloth. Do not use abrasive cleaners or solvents.
Troubleshooting
If you encounter issues with your DIGITEN DFC15 Water Flow Control System, consider the following:
- Solenoid Valve Not Actuating: If you are using a solenoid valve that requires more than 2A, ensure you are using a suitable power adapter capable of supplying up to 5A. The included power adapter is rated for a maximum of 2A.
- Inaccurate Flow Readings: Verify that the flow sensor is installed correctly with the water flow direction matching the arrow on the sensor. Check for any blockages in the flow path.
- Controller Not Powering On: Ensure the 12VDC power adapter is securely connected to both the controller and a functional power outlet.
Warranty
The DIGITEN DFC15 Water Flow Control System comes with a 12-month warranty from the date of purchase, covering manufacturing defects. Please retain your proof of purchase for warranty claims.
