Hayward OnCommand Operation Manual page 23

Countdown Timer – the aux relay will turn on when the AUX button is pressed and then will turn off
automatically after a programmed time (see Timers Menu, Operation Manual). The AUX button can
also be used to turn the output off.
Low Speed of a 2-speed Filter Pump – the OnCommand 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.
Group – the aux relay operates when the Group function is initiated and shuts off when the Group
function is terminated. See Aux1 Group section for operation information for the Group function.
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) or "Dimmer" 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.
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,
dimmer or group.
Aux1 Group
The Aux1 Group function allows the user to perform multiple tasks with a single push of the "Aux1"
button. When setting up a Group function, refer to page 12 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.
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 temperature threshold, the
OnCommand 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.
Aux1 Pump Speed
This is the speed of the pump when the Aux1 output is on. The choices are the Settings Menu speed
and a speed that is unique to the Aux1 output only. 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.
