Dual Equipment" Pool/Spa - Shared Heaters - Hayward Pro Logic Installation Manual

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 in Operation Manual). 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 Pro Logic 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
Pro Logic 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 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
33
5. The chlorinator cell must be installed in the pool plumbing. If spillover is enabled, then the Pro Logic can
chlorinate both the pool and spa (during spillover operation). Otherwise, the Pro Logic 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

Some important notes regarding the Pro Logic control of Dual Equipment Pool/Spa systems with shared heaters:
Pool/Spa Setup
In the Pool/Spa Config., select:
Pool and Spa-Dual
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.
