Why is the free chlorine level too low in my Zodiac Lighting Equipment (murky water)?
- P
  Paul GarciaAug 18, 2025
  The free chlorine level might be too low due to several reasons. The water balance could be incorrect (high pH, etc.), or the Redox set point might be too low. Also, the daily filtering time may be too short. To resolve this: * Check and correct the water balance parameters. * Use the «Boost» mode. * Ensure the set point is above 650mV. * Ensure the daily filtering time is at least 12 hours per day during the season.

What to do if my Zodiac Chlor Expert Lighting Equipment shows an unsuitable or constantly unstable value?
- P
  Philip LewisAug 20, 2025
  If your appliance shows an unsuitable or constantly unstable value, it could be due to a damaged Redox sensor connection cable, a worn Redox sensor, or the Redox sensor cable being too close to an electric cable. Here’s what you can do: * Check the cable and/or the BNC connector. * Reduce the distance between the appliance and the sensor. * Replace the Redox sensor. * Place the sensor in a more suitable location.

Why is the free chlorine level too high in my Zodiac Chlor Expert Lighting Equipment?
- R
  Richard ToddAug 28, 2025
  A high free chlorine level can be caused by an incorrect water balance (low pH, etc.) or a Redox set point that is too high. You should: * Check and correct the water balance parameters. * Ensure the set point is not too high. * Power off the appliance.

What to do if my Zodiac Chlor Expert Lighting Equipment shows a value close to 0mV?
- K
  Kayla LoweAug 29, 2025
  If the appliance consistently displays a value near 0mV, it may indicate a cable problem or a BNC connector issue. Check that the connection between the sensor and the control box is not short circuited (between the cable’s central core and the external shielding). Also, check for humidity and/or condensation at the BNC connector level.

What to do if I get a calibration impossible error message or Redox sensor reliability is less than 25% on my Zodiac Chlor Expert Lighting Equipment?
- J
  Jessica PetersenSep 1, 2025
  If you receive an error message during calibration or the Redox sensor reliability is below 25%, it could be due to a defective buffer solution, a dirty or defective sensor, or a worn sensor. Try the following: * Check that the solution used is 465mV. * Use new buffer solution. * Begin calibration again. * Check the condition of the sensor tip and the porosity of the sensor. * Clean the sensor by leaving its extremity in a 10% solution of hydrochloric acid. * Replace the sensor.

What to do if my Zodiac Lighting Equipment indicates «Flow»?
- J
  Julie JohnsonSep 6, 2025
  If the appliance displays «Flow», it could be due to the filtering being stopped or an incorrect connection. To resolve this: * Start and/or check the filtering. * Check the electric connections.

What does «OFA Check» mean on my Zodiac Chlor Expert Lighting Equipment, and what should I do?
- R
  robert75Sep 8, 2025
  If «OFA Check» is indicated, it signifies a Redox sensor measurement test is in progress because the «OFA Stop» was activated during a previous filtering cycle. Wait for the end of the procedure (1 hour) then check the sensor and/or the pool chlorine level.
