  • Page 24 After calibrating the redox electrode, the setpoint optimisation is out of service for 2 hours, as the redox electrode does not supply reliably si- ® gnals during this period. During this time, the DEPOLOX Pool uses a fixed temporary Cl2 setpoint. This temporary Cl2 setpoint is the last current Cl2 before the calibration (can be altered manually, Menu 2.1.1...
  • Page 25 ® DEPOLOX Pool Description What can be achieved by using CEDOX?  Reduction of disinfectant consumption (as much chlorine as necessary and as little chlorine as is possib- le).  The optimum control of the Cl2 setpoint based on the redox potenti- al means that the lowest possible Cl2 setpoint is always used and thus disinfectant saved.
