Lights, Aux1 and Aux2 Outputs
Standard Relay:
Manual operation of all 3 relays is identical. Assuming that the relay is currently off, simply press
the appropriate button to turn on the relay. If the relay does not turn on, it probably is due to the “interlock” feature
(which was set up in the Configuration Menu) being activated that requires the filter pump to be running and the
valves to be in the pool-only position. This protects pumps and other equipment from possible damage. If the
controlled output is on, pressing the appropriate button again will turn off the relay. Manual turn off is disabled if the
“Freeze Protection” feature is enabled and the air temperature is less than the selected freeze temperature thresh-
old.
Dimmer Relay:
If Lights or an Aux output is configured as a dimmer, pressing the corresponding button will
generate a temporary display which shows the dimmer output level (Off - On 100%). Pushing the “+” or “-”
button changes the level in increments of 20%. When the desired output level is displayed, press the correspond-
ing button again to turn off the display and return to normal operation. When the Lights or Aux output comes on
again (either manually or automatically), the dimmer output level will be the same as the last time that it was set.
External Input Interlock:
If enabled, this function will force the Lights or Aux off when the external input is active. External Input Interlock
will not have precedence over Freeze Protection for Lights and Aux outputs.
Pool/Spa Valves
Pool-only or spa-only systems:
The POOL/SPA button has no function.
Pool and Spa systems without spa spillover:
In pool-only mode, the left LED next to the POOL/SPA button is
illuminated. Pressing the POOL/SPA button will switch the Aqua Plus to spa-only operation (right LED illumi-
nated). Pressing the POOL/SPA button again will switch back to pool-only. Note that the filter pump will turn off
while the pool/spa valves are turning.
Pool and Spa systems with spa spillover:
In pool-only mode, the left LED next to the POOL/SPA button is
illuminated. Pressing the POOL/SPA button will switch the Aqua Plus to spa-only operation (right LED illumi-
nated). Pressing the POOL/SPA button again will switch to spa spillover operation (both LED’s illuminated).
Pressing the POOL/SPA button again will switch back to pool-only. Note that the filter pump will turn off while the
pool/spa valves are turning.
External Input Interlock:
If enabled, this function will force the Valve off when the external input is active. External Input Interlock will not
have precedence over Freeze Protection for Valve outputs
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 will remain in this mode of operation until manually taken out of service mode.
Pressing the SERVICE button again will cause the Aqua Plus to switch to service-timed mode which is very similar
to service mode, except that the Aqua Plus 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 to normal (automatic) operation. See Troubleshoot-
ing/Diagnostic Information (page 30) for more information about the service modes.

•
No Cell Power
-- If no chlorinator cell power is detected on the printed circuit board.
•
Check Flow Switch
-- If the flow switch input is invalid.
•
Cell Power Error
-- If a chlorinator cell power error is detected on the printed circuit board.
•
Cell Missing
-- If the chlorinator is enabled but no cell is detected.
•
Pool Bridge Comm
-- If variable speed is selected for the Pool Filter and the VSC interface is not responding.
•
Pool VSC Comm
-- If variable speed is selected for the Pool Filter and the Hayward VSC is not responding.
•
Pool VSC Err: x
-- If variable speed is selected for the Pool Filter and the Hayward VSC is indicating and
error. x is the same decimal error displayed by the VSC itself.
•
CSM Comm Error:
-- If Chemistry Sensing is enabled and the Chemistry Sense Module (CSM) is not
responding.
•
pH Probe Error
-- If the CSM indicates that there is a problem with the pH probe.
•
pH Low - Check Feeder
-- If a pH level of 6.9 or less is detected, check the feeder for proper operation
•
pH High - Check Feeder
-- If a pH level of 8.1 or higher is detected, check the chemical supply and the
feeder for proper operation
•
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 internal temperature sensor is either an open or short circuit.
