• ORP High - Check Chlor -- If an ORP level of 950mV or higher is detected. Check the chlorinator for proper
operation.
• ORP High - Chlor Off -- If an ORP level of 950mV or higher is detected and the chlorine feed mode is ORP
Auto Sensing, the chlorinator has been turned off. Check the chlorinator for proper operation.
• ORP Timeout -Chlor Off -- If the unit has been chlorinating for more than the selected sanitizer timeout
without reaching the desired level, the chlorinator has been turned off. Press the "+" button to reset the alarm
and resume chlorination.
• Ambient Sensor -- If the Pro Logic internal temperature sensor is either an open or short circuit.
For helpful troubleshooting information on any of these issues, go to the Diagnostic Menu and then scroll through
the various items until you see the cause for the "CHECK SYSTEM" LED being illuminated.
Diagnostic Menu
To enter the Diagnostic Menu, press the "Menu" button repeatedly until the display shows "Diagnostic Menu". At
this point, you can use either the "<" or ">" buttons to scroll through the various menu items which are described
below:
Press to switch chlorinator operation to opposite polarity (15 second delay)
+23.45
Set Day and Time
+6.75A
Wednesday 10:37P
84°F
3200PPM
Move to previous/next menu item
+/- 23.45V is the voltage applied to the chlorinator cell
+/-6.75A is the current (amps) through the cell
84ºF is the water temperature at the cell
3200PPM is the "instant" salt level at this time
This display will be shown only if the chlorinator is enabled. For the chlorinator to be operating,
several other things must be happening: the filter pump must be running, the flow switch must be
detecting flow, the chlorinator setting must be set greater than 0%, the water temperature at the cell
must be between 50ºF and 140ºF, and the salt level must be within the operating range. If any of these
conditions are not met, the chlorinator diagnostic display will tell you the reason. It's possible to have
more than one reason, in which case after you rectify what was displayed the first time, a second
display will appear.
If the current (amps) display is 0.00A, then the chlorinator is operating normally but is in the off part
of its normal operating cycle. Simply press either the "+" or "-" key to start a new cycle.
The Pro Logic periodically reverses the polarity of the voltage applied to the cell in order to automatically
clean off any calcium deposits. It is important that you check the chlorinator operation in both
polarities. To do this, press either the "+" or "-" buttons and the chlorinator will turn off, wait for 15
seconds and then turn on in the opposite polarity.
If a conventional or solar heater is operating, it is likely that the temperature of the water at the cell is
higher than the pool/spa water temperature displayed on the Pro Logic default display.
Instant Salt
Press to load the "Instant Salt" into the averaged salt display
3200 PPM (+=save)
Move to previous/next menu item
This display will be shown only if the chlorinator is enabled. This display shows "Instant Salt" or
"Instant Minerals" (if Chlor. Config. is set for "Display Minerals"). The "Instant Salt" is calculated
based on the voltage, current (amps), and water temperature at the cell. This is different than the
"average salt" value which is displayed as part of the default menu. There are a number of reasons
why instant and average salt readings may differ. Some of these include salt having just been added
to the pool and not yet thoroughly mixed, calcium buildup on the cell, and the cell aging.

The Pro Logic is designed to handle the purification needs of most residential swimming pools up to 40,000 gallons
(150,000 liters), or the needs of most commercial pools up to 25,000 gallons (95,000 liters). Check local codes
for other restrictions. The actual amount of chlorination required to properly sanitize a pool varies due to bather
load, rainfall, temperature, and the pool's cleanliness.
For pools larger than 40,000 gallons, the Pro Logic can control one or more Hayward Aqua Rite chlorinators to
supplement chlorine production.
NOTE: Before installing this product as part of a saline water purification system in a pool or spa using natural
stone for coping or for immediately adjacent patios/decking, a qualified stone installation specialist should be
consulted regarding the appropriate type, installation, sealant (if any) and maintenance of stone used around a
saline pool with electronic chlorine generator in your particular location and circumstances.
NOTE: The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in arid regions where
pool water is subject to excessive evaporation and is not commonly diluted with fresh water. Dry acid can cause a
buildup of by-products that can damage your chlorinator cell.

Default Display

Turn power on at the main panel and turn the Pro Logic control power circuit breaker on. The keypad will show
the default display. The default display alternates between the day/time, air and pool (or spa) temperature, pool/
spa sanitizer setting, and salt level. Under certain circumstances, additional displays may be added to the default
menu to inform you about system operation. Refer to the Programming Menu Flowchart on page 6 to view all
possible displays. The Pro Logic will automatically scroll through all of the available default menu displays or you
can press "<" or ">" to manually scroll.
