4. The Aqua Plus 16v can be programmed to accommodate spillover if desired. Note that spillover operation
will be automatically suspended whenever the spa filter pump is turned on.
5. The chlorinator cell must be installed in the pool plumbing. If spillover is enabled, then the Aqua Plus 16v
can chlorinate both the pool and spa (during spillover operation). Otherwise, the Aqua Plus 16v will only
chlorinate the pool and the spa sanitization will have to be handled manually.
6. If any water feature or pressure side cleaner boost pumps are used, be sure to enable the “interlock”
feature (see “Configuration Menu” for details) to ensure that the pumps operate only when the “Pool
Filter” pump is on and the system is in the “pool only” operating mode.
7. The plumbing diagram on page 9 is intended to be used as a general guideline and is not a complete
plumbing schematic for the pool.
8. When using the wireless spa-side remote control (AQL2-SS-RF), the “POOL” button will position the
valves for Pool mode and the “SPA” button will position the valves for Spillover mode.
“Dual Equipment - Shared Heaters” for Pool/Spa configuration
These systems have 2 complete sets of equipment (filter pump, filter) and shared heaters. Refer to the diagram
below:
Some important notes regarding the Aqua Plus 16v control of Dual Equipment Pool/Spa systems with shared
heaters:
In the Pool/Spa Config., select:
Pool/Spa Setup
Pool and Spa-Dual
Heaters
Shared
1. When dual equipment is selected:
a. The “filter” pump automatically is renamed “Pool Filter” and can not be changed. The pool filter
can be a one, two or variable pump.
b. The “Aux1” output is automatically renamed “Spa Filter”, its function is set to “Timeclock” and the
Interlock feature is forced to “Disabled”. None of these can be changed. The spa filter can be a
one, two or variable pump.
c. The Valve3 configuration menu is disabled.
d. The heater(s) will be dedicated to the spa whenever the spa filter is on and the spa temperature
setting is not off.
2. The water sensor should be installed on the pool loop prior to the heater(s) and will display the pool
temperature whenever the “Pool Filter” pump is running.
3. The dual equipment spa sensor should be installed on the spa loop prior to the heater(s) and will display
the spa temperature whenever the “Spa Filter” pump is running.

speed are controlled by commands sent to the VSP. Note: Up to 6 Lights/Aux outputs can be
configured as VSP relays.
Lights Interlock
If enabled, this feature will override the function (Manual On/Off, Countdown Timer, Timeclock)
selected above and turn the lights relay off when: filter pump is off, first 3 minutes of filter pump
operation (allows the pump to prime and get water flowing), when the pool/spa suction return valves
are in any position other than “pool only”, or for the first 3 minutes after solar turns on (allows air in
the solar panels to be purged). Interlock is not available for solar, low speed filter pump, dimmer,
group, super chlorinate, or pH dispense functions.
Lights Group
The Lights Group function allows the user to perform multiple tasks with a single push of the “Lights”
button. When setting up a Group function, refer to page 22 for specific programming information.
There are two Group menus; the first menu determines how the group command will be initiated
(Manual On/Off, Countdown Timer, or Timeclock) and the second menu selects the desired functions
and their respective control parameters.
When activating Group functions, be aware that the most recent Group function that is initiated will
override any previous Group function.
Lights External Input Interlock
When Lights External Input Interlock is enabled, the lights output will be forced off when the external
input is active. This will have precedence over freeze protection. Lights External Input Interlock is not
available for solar, low speed filter pump, dimmer, group, super chlorinate, or pH dispense functions.
Lights Freeze Protection
This function helps protect equipment that is wired to the lights relay against freeze damage. If Freeze
Protection is enabled and the AIR temperature sensor falls below the selected freeze temperature
threshold, the Pro Logic will energize the lights relay. IMPORTANT: this only enables operation of the
lights relay during freeze--see the “Filter Pump Config.” menu to enable freeze protection for the main
circulation system. Freeze Protection is not available for low speed filter pump, dimmer, group, super
chlorinate or pH dispense functions.
Lights Pump Speed
This is the speed of the filter pump when the Lights output is on. The default selection is “Settings
Menu”. This is the speed of the pump that has been selected in the Settings Menu for normal filter
operation. If an alternate speed is desired when the Lights output is on, push “+” or “-” and select from
“Filter Lowest” to “Filter Highest” in 5% increments.
NOTE: The configuration parameters for all Aux outputs are the same as shown below for Aux1. PS-4: Aux1 and Aux2. PS-8:
Aux1 through Aux6. PS-16: Aux1 through Aux14. Also note that for the PS-16, Valves7, 8, 9 and 10 are turned On/Off with the
control function selected for Aux7, 8, 9, and 10, respectively.
