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 through-
out 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 80 ppm.

Solar Priority
If both “Solar Control” and “Heater Control” are enabled, the Solar Priority feature will keep
the conventional heater off whenever solar heat is available. This provides the most cost
effective way of heating the pool. When solar heat is not available, the conventional heater
will operate normally.
Allow Low Speed
This menu only appears if the pool filter is configured for 2-speed or variable speed operation.
During default operation, high speed mode is used whenever the solar heater is on. If Allow
Low Speed is enabled, low speed pump operation will be allowed during solar heating except
for the first 3 minutes after solar heat turns on.

Lights Function
Although designated as the “Lights” output, the function of the lights relay is similar to the
aux1 and aux2 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
will not be necessary 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 (default)
—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 in Operation
Manual). The LIGHTS button can also be used to turn the output off.
Low Speed of a 2-speed Filter Pump
– the Pro Logic 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 Timers Menu (see Timers 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. It is important to note that “Solar Control” must be enabled in the “Solar Config.”
