Troubleshooting & Service Mode; Diagnostic Information Check System Indicator - Hayward Pro Logic® Operation Manual

Troubleshooting and Diagnostic Information
The Pro 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 opera-
tion, call the Hayward Technical Service Dept. from Monday through Friday, 8AM to 8PM EST at 908-355-
7995.
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 Pro
Logic will remain in this mode of operation until manually taken out of service mode.
Pressing the "SERVICE" button again will cause the Pro Logic to switch to service-timed mode which is very
similar to service mode, except that the Pro 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 displayed on the
remote display(s).
Pressing the "SERVICE" button again, will return the Pro Logic to normal (automatic) operation.
Check System Indicator
The "CHECK SYSTEM" LED will alert you when the Pro Logic detects any of the following conditions that are
abnormal and require attention for optimal operation of your pool. Press "<" or ">" to view all of the existing
"Check System" conditions.
• Inspect Cell -- For optimum operation, you will need to inspect the Pro Logic chlorinator cell approximately
every 3 months and clean the cell if necessary. The Pro 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 and then press the "+"
button during the "Inspect Cell" display to reset the timer.
• Low Salt/Minerals or Very Low Salt/Minerals -- When the salt is too low the Pro Logic will generate less
chlorine and the life of the cell is degraded. Check the cell and clean if necessary before adding salt.
• High Salt/Amps/Minerals -- The Pro 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/Pool Sensor -- If the water or pool (if Dual Equipment) 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 Solar is enabled and the solar sensor is either an open or short circuit.
• Spa sensor for Dual Equipment-- If dual equipment spa sensor is either an open or short circuit.
• Chlorinator Cell sensor -- If the chlorinator function enabled (Configuration Menu/Chlorinator) and the cell
sensor is either an open or short circuit.
