pH Feed Timeout
To protect the pool, the AquaRite Pro will automatically shut down pH control and display a
"Check System" message if the pH dispensing device runs continuously for more than the se-
lected timeout value. This prevents a situation where the AquaRite Pro is constantly feeding pH
reducer because of a probe error or external problem with the pool and allows the pool owner to
evaluate the pool chemistry before continuing with pH control. Use the "+" and "-" buttons to
select a preset timeout value from 5 to 120 minutes. If the AquaRite Pro exceeds this pH Feed
Timeout, it can be reset in the Check System display.
Maintain ORP Level
The Wizard prompts you to enter the desired ORP level (650mV default). Note that the AquaRite
Pro will attempt to maintain this level but typically the pool's ORP level will vary above this value
during normal operation. The adjustable range is from 400mV to 900mV in 5mV increments.
ORP Alarms
The AquaRite Pro will automatically set a high and low alarm for the ORP level. The high
alarm point is 850mV and the low alarm point is 350mV. If the ORP level meets or exceeds
these points, an alarm message will display locally and on all remote controls. Also, if the ORP
level is too high, chlorine generation will shut down.
Sanitizer Feed Timeout
When the Chlorine Feed selection is set to ORP Auto Sensing, the AquaRite Pro will automati-
cally shut down ORP control and display a "ORP Timeout" message if the timeout value is ex-
ceeded (1-24 hours). This prevents a situation where the AquaRite Pro is constantly generating
chlorine because of a probe error or external problem with the pool and allows the pool owner
to evaluate the pool chemistry before continuing with ORP control. The Timeout can be reset
in the Check System Default Menu display.
pH Calibration Wizard
After installation, the pH probe must be calibrated using the pH Calibration Wizard. Periodically,
a pool water test should be compared to the pH level reported by the AquaRite Pro. If there is
a discrepancy between the two values, the pH Calibration Wizard should be redone.
Run the pool pump for a minimum of 20 minutes before starting the pH Calibration Wizard. The
procedure to perform the Wizard is shown below. Detailed information about specific screens
can also be found below.
1. Press the button.
2. Press ">" repeatedly until "pH Calibration Wizard" is displayed.
3. Push "+" to start Wizard.
4. Advance through the Wizard using "<" and ">" buttons. Use "+" and "-" buttons to answer
questions when prompted.
5. Continue until finished.
Enter Independent pH Test Result
Test the pH of the pool water with a dependable quality test kit after the pool pump has been
running for a period of time. Hayward suggests that you take more than one test and average
the results before entering the value in the pH Calibration Wizard. After entering the pH value,
press the "+" button to calibrate the pH probe. A "Check System" warning will display if the
probe value and the entered value are different by ± 1.0 or greater. If this is the case, retest the
pH (possibly with another test kit) and consider cleaning the pH probe per the instructions found
in the Probe Maintenance section of this manual.
