High Voltage (120/240V) Pool Equipment
All ECOMMAND 4 relays are double pole (they make/break both “legs” of 240V circuits) and are rated
at 3HP/30A at 240V (1½HP/30A at 120V). Refer to the diagram below for typical relay wiring.
WARNING: Do not use the ECOMMAND 4 to control an automatic pool cover.
Swimmers may become entrapped underneath the cover.
Two speed filter pump: Requires 2 relays (FILTER plus one of the AUX relays) for proper operation of
both speeds.
IMPORTANT: Be sure to follow the wiring diagram below AND to configure
the control logic according to the instructions on page 14.
Lights: A ground fault circuit breaker must be used to supply power for high voltage pool/spa lighting.
Low voltage lights will require an external transformer. For lighting systems that have both a light source
and color wheel, connect the light source to the “Lights” relay and then connect the color wheel to one of
the AUX outputs.

Super Chlorinate – if “Chlorinator” is enabled, this option allows the user to start a Super
Chlorinate cycle when the Lights button is pressed, rather than using the Settings Menu.
Note that only one button can be assigned to this function.
Lights Relay
This feature allows the user to select either “Standard” (default) or “Dimmer” 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.
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 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 ECOMMAND 4 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 pump when the Lights output is on. The choices are the Settings
Menu speed and a speed that is unique to the Lights 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 Lights output is on, push
“+” or “-” and select from “Lowest” to “Highest” in 5% increments.
NOTE: The configuration parameters for the Aux2 output are the same as shown below for Aux1.
