Low Speed of a 2-speed Filter Pump
– the Pro Logic will operate the aux 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 aux relay will turn-on and turn-off at the times set for the aux1 timeclock in the Timers
Menu. The AUX button can also be used to turn the output on and off.
Solar
– the aux relay operates 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. It is important to note that
“Solar Control” must be enabled in the “Solar Config.” menu for proper operation to occur.
Super Chlorinate
– if “Chlorinator” is enabled, this option allows the user to start a Super Chlorinate cycle
when the Aux button is pressed, rather than using the Settings Menu. Note that only one button can be
assigned to this function.
Aux1 Relay
This feature allows the user to select either “Standard” (default), “Dimmer” or “VSP” type relay for the
Aux1 output. The optional AQL-DIM dimmer kit must be installed if “Dimmer” is desired.
When “Dimmer” is selected, and the Aux1 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 aux1 output is turned from off to
on.
If “VSP” is selected, the Aux relay is used to supply power to a Hayward Variable Speed Pump (VSP). The
relay will be on when the Aux output is on and off when the output is off. On, off and speed are controlled
by commands sent to the VSP.
Aux1 Interlock
If “Enabled”, this feature will override the function (Manual On/Off, Countdown Timer, Timeclock), selected
above and turn the aux1 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, super chlorinate or dimmer.
Aux1 External Input Interlock
When Aux1 External Input Interlock is enabled, the Aux1 output will be forced off when the external input
is active. This will have precedence over freeze protection. Aux1 External Input Interlock is not available
for solar, low speed filter pump, dimmer, group, super chlorinate, or pH dispense functions.
Aux1 Freeze Protection
This function protects the pool, plumbing, and equipment against freeze damage. If Freeze Protection is
enabled and the AIR temperature sensor falls below the selected freeze protection temperature, the Pro
Logic will turn on the aux relay to circulate the water. IMPORTANT: this only enables operation of the
AUX output 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.
Aux1 Pump Speed
This is the speed of the filter pump when the Aux1 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 Aux1 output is on, push “+” or “-” and select from “Lowest” to
“Highest” in 5% increments.

Pool Sizing Formula
Type of Salt to Use
It is important to use only sodium chloride (NaCl) salt that is greater than 99.0% pure. This can be found at most pool
stores in 40-80 lb. bags labeled “for use in swimming pools”. Alternatively, use common food quality or water softener
salt that is at least 99.0% pure. It is also acceptable to use water conditioning salt pellets, however, it will take longer
for them to dissolve. Do not use rock salt, or salt with more than 1% of yellow prussiate of soda, salt with anti-caking
additives, or iodized salt.
How to Add Salt
For new plaster pools, wait 10-14 days before adding salt to allow the plaster to cure. Turn the circulating pump on
and add salt directly into the pool. Brush the salt around to speed up the dissolving process—do not allow salt to pile
up on the bottom of the pool. Run the filter pump for 24 hours with the suction coming from the main drain (use pool
vacuum if there is no main drain) to allow the salt to evenly disperse throughout the pool. The salt display may take 24
hours to respond to the change in salt concentration.
Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the
chart below to determine how much stabilizer must be added to raise the level to 30 ppm.
