Circuit Breaker Installation and Wiring
Circuit breakers are to be supplied by the installer. Refer to the circuit breaker chart below for a list of
suitable circuit breakers that can be used. Follow the code and the circuit breaker manufacturer’s rating
requirements regarding the size and temperature rating for wiring. Note that some pool equipment may be
required to be connected to ground fault circuit breakers—check local and NEC (CEC) codes.
General Purpose Outlet
If desired, a duplex receptacle with weatherproof cover (supplied by installer) may be installed in the
knockouts on the lower right side of the ECOMMAND 4 enclosure. Per code, the receptacle should be
a GFCI type. Alternatively, connect a standard receptacle to a GFCB.
ECOMMAND 4 Control Power
The ECOMMAND 4 requires 120VAC, 2A power to operate the control logic circuits. This power
should be connected to a circuit breaker rated at 125% of the intended load or the next higher size
available.

Aux1 Function
Manual On/Off (default)—the aux relay will alternate between turning on and off when the
aux button is pressed. There is no automatic control logic.
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 ECOMMAND 4 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) 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 or dimmer.
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 ECOMMAND 4 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.
