Troubleshooting and Diagnostic Information
The Aqua Logic provides 2 different tools to aid in troubleshooting any problems that may occur in your
pool and/or spa system. The Service mode will allow you to disable automatic operation and manually
control most of the equipment (the heater and general purpose Valve3 output are the exceptions). The
Diagnostic Menu will provide some detailed information regarding system operation.
While both of the features are primarily intended for the use of the professional service technician, their
function is fully explained below. If you believe your system is not operating properly or have questions
regarding the operation, call the Goldline Technical Service Dept. from Monday through Friday, 8AM to
8PM EST at 888-9221-7665.
Service Mode
The main unit keypad has a SERVICE button that is used primarily during servicing of the pool equipment.
If you want to completely disable the automatic operation and operate the system manually, you can put
the system into Service or Service-Timed mode by pressing the “Service” button. Pressing the “Service”
button once will switch the system into service mode which means that all automatic functions are disabled,
the optional remote display/keypads are disabled (except for manual turn off for emergencies). The
outputs can be manually controlled by pressing the buttons on the local display/keypad. The red service
LED will be illuminated and the Aqua Logic will remain in this mode of operation until manually taken out
of service mode.
Pressing the “Service” button again will cause the Aqua Logic to switch to service-timed mode which is
very similar to service mode, except that the Aqua Logic will automatically return to normal operation after
3 hours. During service timed operation, the service LED will flash and the time remaining will be dis-
played on the remote display/keypad(s).
Pressing the “Service” button again, will return the Aqua Logic to normal (automatic) operation.
Check System Indicator
The “Check System” LED will alert you when the Aqua Logic detects conditions that are abnormal and
require attention for optimal operation of your pool. The following conditions will cause the “Check Sys-
tem” LED to illuminate:
• Inspect Cell—for optimum operation, you will need to inspect the Aqua Logic chlorinator cell approxi-
mately every 3 months and clean the cell if necessary. The Aqua Logic will automatically remind you
when it is time and display “Inspect Cell, + to reset” as part of the rotating Default Menu. Clean the cell
(see instructions, pg 20) and then press the “+” button during the “Inspect Cell” display to reset the
timer.
• Low Salt—when the salt is too low the Aqua Logic will generate less chlorine and the life of the cell is
degraded. Check the cell and clean if necessary (see instructions, pg 20) before adding salt (see in-
structions, pg 17).
• High Salt—the Aqua Logic will stop generating chlorine under certain high salt conditions in order to
protect the internal electronics from damage. The only way to lower the salt level is to partially drain the
pool and add fresh water.
• Water Sensor—if the water sensor is either an open or short circuit.
• Air sensor—if the freeze protection feature is enabled (Configuration Menu / Filter Config.) and the air
sensor is either an open or short circuit
• Solar sensor-if the solar control feature is enabled (Configuration Menu / Solar Config.) and the solar
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.
