Hayward Pro Logic PL-P-4-CUL Installation Manual page 29

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, super chlorinate or dimmer.
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, 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.
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 the Aux2 output are the same as shown below for Aux1.
