VSP Relay
: This selection is used to configure a Lights/Aux output to supply power and control a Hayward
Variable Speed pump (VSP).
Pool/Spa Valves
Pool-only or Spa-only systems:
The POOL/SPA/SPILLOVER button has no function.
Standard Pool and Spa systems without spa spillover:
In pool-only mode (“POOL” LED illuminated), press
the “POOL/SPA/SPILLOVER” button to switch to spa-only operation (“SPA” LED illuminated). Pressing the
“POOL/SPA/SPILLOVER” button again will switch back to pool-only. Note that the filter pump will turn off
while the pool/spa valves are turning.
Standard Pool and Spa systems with spa spillover:
When currently in the pool-only mode (“POOL” LED
illuminated), press the “POOL/SPA/SPILLOVER” button to switch to spa-only operation (“SPA” LED illumi-
nated). Press the button again to switch to spa spillover operation (“SPILLOVER” LED illuminated). Pressing the
“POOL/SPA/SPILLOVER” button again will switch back to pool-only mode. Note that the filter pump will turn
off while the pool/spa valves are turning.
Dual Equipment Pool and Spa systems without spa spillover
: The POOL/SPA/SPILLOVER button has no
function. The “POOL” LED will always be illuminated.
Dual Equipment Pool and Spa systems with spa spillover
: When currently in the separate Pool and Spa loops
mode (“POOL” LED illuminated) and the Spa Filter is off, press the POOL/SPA/SPILLOVER button to switch
to spa spillover operation (“SPILLOVER” LED illuminated). Press the POOL/SPA/SPILLOVER button again to
return to the separate Pool and Spa loops mode of operation. Note that the Pool Filter pump will shut off while the
pool/spa return valve is turning. The system will automatically switch out of spillover whenever the spa filter pump
is turned on. NOTE: For Dual Equipment Pool and Spa systems, there is no Spa Only mode.
Heaters
This description applies to Heater1 and to Heater2, if programmed (note that the function of the Valve4 button
changes to Heater2 when Heater2 is enabled). Pressing the “HEATER” button causes the Aqua Plus 16v to switch
the heater control output between a “forced off” state and a normal, automatic thermostatic control operating state.
System Off
Each remote display/keypad has a red “SYSTEM OFF” button on the upper left corner of the keypad. Pressing
this button will turn all outputs off and they will remain off, regardless of any programmed control logic, until either
the “SYSTEM OFF” button (on any remote display/keypad) is pressed again or the “SERVICE” button is pressed
on the display/keypad at the main unit. The red “SYSTEM OFF” LED will illuminate to indicate that all outputs and
being forced off.
!
WARNING: pressing the “SYSTEM OFF” button overrides any programmed freeze protection
and may cause damage to your system in freezing conditions.
Service
The main unit keypad has a “SERVICE” key. This button 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, and the remote
display/keypads are disabled (except for manual turn off for emergencies). 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 keypad(s).
Pressing the “SERVICE” button again, will return the Aqua Plus 16v to normal (automatic) operation. See Trouble-
shooting/Diagnostic Information for more information about the service modes.

pH Timeout - Check Feeder
-- If the unit has been dispensing pH for more than the selected timeout without
reaching the desired level. Check the chemical supply and the feeder. If both are OK, the timeout may need to
be increased. Press the “+” button to reset the alarm and resume dispensing.
•
pH Calibration Error
-- When using the pH Calibration Wizard and the entered test result was different from
the measured pH level by ± 1.0 or more. The pH probe may need to be cleaned or replaced.
•
ORP Probe Error
-- If the CSM indicates that there is a problem with the ORP probe.
•
ORP Low - Check Chlor
-- If an ORP level of 350mV or less is detected. Check the chlorinator for proper
operation.
•
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 Aqua Plus 16v 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:
Set Day and Time
Wednesday 10:37P
Move to previous/next menu item
+23.45 +6.75A
84°F 3200PPM
Press to switch chlorinator operation to opposite polarity (15 second delay)
+/- 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 Aqua Plus 16v 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 Aqua Plus 16v default display.
