c. Overfeed Timer
The ORP overfeed timer is a safety function turning off
the dosing if the ORP setpoint is not reached under a
certain amount of time.
• Avoid overdosing of chemicals in case of wrong /
inconsistent ORP measurement for a long period
of time.
• Detect saltwater chlorinator issues.
• Default: The ORP overfeed timer will turn on after
36 hours of chlorination without reaching the ORP
setpoint.
• The ORP overfeed timer can be modified using the
"Dose time" pushbutton in ORP mode.
Default: 36 hours
Selectable range: 12 hours to 96 hours of
chlorination (12 hours increment).
Increase the Overfeed timer if the unit is not able to
maintain the defined ORP setpoint and triggers the
ORP overfeeding alert regularly.
• Display: The ORP LED is blinking in the auto mode
and "Er2" is displayed on the LCD screen.
• The overfeed timer does not automatically reset. It
must be reset by turning the controller off and then
on or cycling the mode out of auto and back to auto.

4.4.4 Flow
The integrated flow switch is pre-wired to the controller.
The flow switch must be installed for safety reasons to
prevent dosing chemicals when there is no flow in the
circulation piping.
NOTE: Install the small in-line filter on the intake
tubing going to the flow cell. Not installing it
could potentially lead to malfunction of the flow
switch.
