NOTE: Heater1 and Heater2 configuration are identical. If Heater2 is enabled then Valve4 will automatically be disabled due
to the fact that they use the same output relay and only 1 function can be assigned to that relay.

Heater1
If the heater is “Enabled”, the heater relay will turn on when the water temperature is less than the
desired temperature setting and the filter pump is running. The desired temperature is in the “Settings
Menu”. If applicable, the homeowner will be prompted to enter separate “pool” and “spa” settings.
Depending on the position of the pool/spa suction valves, the proper temperature setting will be
used.
Heater Name
The Aqua Plus 16v allows you to assign any one of a number of names (e.g. “Gas Heater, Heat Pump,
etc.) to each of the heater control functions. This will make the Aqua Plus 16v much more user
friendly to the homeowner when they want to turn various heaters on or off or set temperatures. A
sheet of small name labels is included with the Aqua Plus 16v main unit and each remote display/
keypad so that appropriate pushbuttons can be labeled the same as the name that you have as-
signed.
Heater Cooldown
This feature ensures that the heater cools down before water circulation is stopped. When enabled,
the Aqua Plus 16v will continue to run the filter pump for 5 minutes after the heater turns off. During
this period the filter pump LED will flash and also a “Heater Cooldown, X:XX remaining” message will
scroll on the display.
When the filter pump is running and the heater is on: Pressing the “Filter” button once will cause the
heater to turn off, but the filter pump will continue to run for heater cooldown (filter LED flashing and
message on display). Pushing the filter button a second time will override the heater cooldown
operation and turn the filter pump off.
For a Pool/Spa Setup selection of “Pool Only”, “Spa Only” or “Pool and Spa-Std”, Heater1 and/or
Heater2 cooldown affect the filter pump. For “Pool and Spa-Dual”, Heater1 is associated with the spa
filter and Heater2 with the pool filter.
Heater Extend
If “Enabled”, the filter extend logic keeps the filter pump running beyond the normal turn-off time until
the pool (or spa) is heated up to the desired temperature setting (see Settings Menu). Heater extend
will NOT cause the filter pump to turn on, it will only delay the turn off time when the heater is
operating.

Lights Function
Although designated as the “Lights” output, the function of the lights relay is similar to the Aux
relays. If pool lights are wired to the lights relay, some options including Solar function, Low Speed
of a 2-Speed Filter Pump, Lights Interlock and Lights Freeze Protection are not applicable and should
be disabled. If no pool lights are used, the lights relay can be used to control other pool devices that
may require these options. The function of each option is shown below.
Manual On/Off
—the lights relay will alternate between turning on and off when the LIGHTS button is
pressed. There is no automatic control logic.
Countdown Timer
—the lights relay will turn on when the LIGHTS button is pressed. The lights relay
will turn off automatically after a programmed time (see Timers Menu). The LIGHTS button can also
be used to turn the output off.
Low Speed of a 2-speed Filter Pump
– the Aqua Plus 16v will turn on the lights relay whenever the low
speed operation of the filter pump is required. It is very important that the “2-speed” filter pump
option be selected under the “Filter Config.” Menu for proper operation.
Timeclock
– the lights relay will turn-on and turn-off at the times set for the lights timeclock in the
Settings Menu (see Settings Menu). The LIGHTS button can also be used to turn the output on and
off.
Solar
– the lights relay can operate a solar booster pump which will turn on when the filter pump is
running and solar heat is available and the water is less than the desired temperature setting. Note
that “Solar” must be enabled in the “Solar Config.” menu for proper operation to occur.
Low Speed of a 2-Speed Spa Filter Pump
– the Aqua Plus 16v will turn on the lights relay whenever
the low speed operation of the Dual Equipment Spa filter pump is required. “Pool and Spa-Dual”
(located in Pool/Spa Setup menu) and “2-Speed” (located in Spa Filter Config. menu) must be selected
for proper operation.
Group
– the lights relay operates when the Group function is initiated and shuts off when the Group
function is terminated. See Lights Group section for operation information for the Group function.
Super Chlorinate
– The Super Chlorinate function can be assigned to any Aux, Lights or Valve
button. This allows the user to simply hit a button to start a Super Chlorinate cycle, rather than using
the Settings Menu. Note that only one button can me assigned to this function.
pH Dispense
–When Chemistry Sensing is enabled and pH Reduction Control is NOT disabled, the
Aqua Plus 16v will turn on the Lights relay when there is a need to energize the pH dispensing device.
The pH Dispense function can be assigned to any Aux or the Lights output. Once programmed for pH
Dispense, the Lights button will have no function. Requires the use of the AQL-CHEM sensing kit.
Lights Relay
This feature allows the user to select either “Standard” (default), “Dimmer” or “VSP” type relay for the
Lights output. The optional AQL-DIM dimmer kit must be installed if “Dimmer” is desired.
When “Dimmer” is selected, and the Lights output is manually turned on, the “+” and “-” buttons
adjust the level from 20% to 100% (default). The level is saved for the next time the lights are turned
from off to on.
If “VSP” is selected, the Lights relay is used to supply power to a Hayward Variable Speed Pump
(VSP). The relay will be on when the Lights output is on and off when the output is off. On, off and
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 15 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.
