Troubleshooting cont.
Observation
Digital Display not
illuminated (continued
from previous page)
Digital Display is reading
a flow rate that is
significantly different to
the FlowVis
Turnover rate appears to
be inaccurate
External equipment such
as a Heater or Chemical
Feeder, that is being
controlled by the Auxiliary
Output, is turning on and
off erratically
Display is showing
the wrong unit of
measurement
16. Environmental

Solution
•
If the blue light is flashing, the sensor has not detected a magnet in the FlowVis indicator
arm. Contact H2flow for further assistance.
•
Is this a retrofit to an existing FlowVis? If yes, did you install a new lid assembly that is
'Digital' compatible? If no...
•
Contact H2flow for further guidance
•
Check that the DIP switch settings applied in 'Programming' section, correcly related to
the FlowVis model being used. If applied correctly, please contact Dryden Aqua for further
guidance.
•
The turnover rate is calculated by the programmed pool volume, divided by the flow
rate. Perform a manual calculation as follows: (Pool Volume ÷ Flow Rate from FlowVis) ÷
60 = Turnover rate in hours. If this number is different to the value shown on the FlowVis
Display, reconnect your laptop and check that the pool volume has been accurately
entered.
•
Reconnect laptop PC and check that the Sensitivity Level has been set to 'Low' . If yes...
•
Check the flow rate reading is well above (or below) the set level programmed to turn
on (or off ) the Auxiliary Output. If the actual flow rate is close to the set value and there is
turbulence causing the flow rate to be erratic, consider adjusting the set point value.
•
Connect your laptop and check to see the required Unit of Measurement (US GPM, LPM
or M
/hour) has been selected. Change as necessary.
