function identically, but conform to different International requirements.
This user guide will refer to EL systems for the sake of simplicity, but the

EL/GL SERIES (Mach 2.1) CONTROL WITH ML900 PANEL

The ML900 panel can be used with the EL8000, EL5000,
EL2000 and EL1000 systems. This user guide lists all
features that are available. Your spa may not respond as
described in this document as specific operation varies
by system and equipment used. If your spa is not fully
equipped, the panel buttons on your spa control may
not be laid out as shown.

The pump responsible for heating and filtration (pump 1
low on non-circ systems, or the circ pump on circ
systems) will be referred to simply as the pump.

Timeouts refer to a preset length of time that a
function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can
cause a function to operate longer, while faults can
cause a function to operate for a shorter length of time.
The system keeps track of timeouts regardless of other
conditions occurring.

In multi-button sequences, if buttons are pressed too
quickly in sequence, they may not register.

Initial Start-up

When your spa is first actuated, it will go into Priming
mode (after displaying some configuration information).

Please see the M-7 Installation Instruction Manual
for complete instructions on Power-up and
Pump Priming.

Icon Legend

Heat Icon - Indicates different stages of heating.

Jets Icon - Spins fast on high speed; spins
slow on low speed.

Blower Icon - Biggest in highest speed;
smallest in lowest speed.

The Priming mode will last for up to 4 minutes and
then the spa will begin to heat and maintain the water
temperature in the Standard mode. You can exit Priming
mode early by pressing “Warm” or “Cool.”

Fiber-Optic Light Icon - Spins when the
wheel is on; stands still when wheel is off.

Light Icon - On dim, the LCD will show
the center circle plus one quarter of the
light beams. Half of the light beams will
show on medium brightness, and all of
the light beams will show on bright.

Time

When time hasn’t been programmed, the “ ” icon
flashes. To set the time, press “Time” then “Mode/Prog.”
Use the “Warm” and “Cool” buttons to adjust time.
See previous page for more detailed instructions.

(Time settings on EL1000 and EL2000 systems are not
preserved in the event of power loss; time will have to be
reprogrammed upon each power up.)

If your spa has an optional pH/ORP sensor (not
available on EL1000 and some EL2000 systems), pressing
“Time” twice will display the current pH level; pressing
it three times will display the current ORP.

Setting the Time

Once the spa has been properly connected the first time (every
power up on the EL1000 and EL2000 systems), notice the “
appearing on the screen.

Temp Set (80°F - 104°F / 26.0°C - 40.0°C)

The last measured temperature is constantly displayed
on the LCD.

Note that the last measured spa temperature
displayed is current only when the pump has been
running for at least 2 minutes.

Warm/Cool

Press the “Warm” or “Cool” button once to display the
set temperature. Each time either button is pressed again,
the set temperature will increase or decrease depending
on which button is pressed. After three seconds,
the LCD will automatically display the last measured
spa temperature.

Mode/Prog

This button is used to switch between Standard,
Economy, and Sleep modes. Press “Mode/Prog” to enter
mode programming, press “Cool” to cycle through to
desired mode (LCD flashes until confirmed), then press
“Mode/Prog” to confirm selection.

Standard mode maintains the desired temperature.
Note that the last measured spa temperature displayed
is current only when the pump has been running for at
least 2 minutes. The “
the mode is changed.

Economy mode heats the spa to set temperature only
during filter cycles. The “

Pressing “Jets 1” while in Economy mode puts the
spa in Standard-In-Economy mode, which operates
the same as Standard Mode, then reverts to Economy
Mode automatically after 1 hour. Both the “
and “

” icons display in this mode. During this

”

time, a press of the “Mode/Prog” button will revert to
Economy Mode immediately.

Sleep mode heats the spa to within 20°F (11°C) of the
set temperature only during filter cycles. The “

”

icon will display until mode is changed.

Standby Mode

Pressing “Warm” or “Cool” then “Jets 2” will turn off all
spa functions temporarily. This is helpful when changing
a filter. Pressing any button resets the spa. On some
systems the “Jets 1” button will control the pump in
Standby Mode (“Drain Mode”). In this case, press any
other button to exit. System will revert to previous mode
after 1 hour.

Jets 1

Press the “Jets 1” button once to turn pump 1 on or off,
and to shift between low and high speeds if equipped.
If left running, the pump will turn off after a timeout
period. The pump 1 low speed timeout on some systems
may be as long as 4 hours.

On non-circ systems, the low speed of pump 1 runs
when the blower or any other pump is on. It may also
activate for at least 2 minutes every 30 minutes to detect
the spa temperature (polling) and then to heat to the
set temperature if needed, depending upon mode.
When the low speed turns on automatically, it cannot
be deactivated from the panel; however, the high speed
may be started.
