Incorrect Flow Value 

If the controller is reporting an incorrect flow value, make sure the K-value is correct. 

No Flow 

If the controller is reporting No Flow:

1.  Verify that water is actually flowing. 

• Manually run a valve and visually confirm that water is flowing
  
  

2.  Verify the wiring. 

• Refer to the installation guide
• Every flow sensor is different so be sure to use the appropriate flow meter's documentation.
  
  

3.  Test Flow biCoder by performing a Tap Test. 

• Tap yellow and white wires together
• Make sure the LED blinks
• If it  fails, replace the Flow biCoder

Note: In some cases it may be necessary to take the flow device, and biCoder to the controller to manually/self test it at the terminals by themselves to rule out wire path issues. When running a self test on that flow biCoder, activate the flow device/register to identify if the controller reads flow on the test screen.
