Troubleshooting and Diagnostic Information
The Aqua Plus 16v 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 Aqua
Plus 16v will remain in this mode of operation until manually taken out of service mode.
Pressing the “SERVICE” button again will cause the Aqua Plus 16v to switch to service-timed mode which is very
similar to service mode, except that the Aqua Plus 16v 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 Aqua Plus 16v to normal (automatic) operation.
Check System Indicator
The “CHECK SYSTEM” LED will alert you when the Aqua Plus 16v 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 Aqua Plus 16v chlorinator cell approxi-
mately every 3 months and clean the cell if necessary. The Aqua Plus 16v 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 Aqua Plus 16v 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 Aqua Plus 16v will stop generating chlorine under certain high salt condi-
tions 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.
