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.
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.”
Jets Icon - Spins fast on high speed; spins
slow on low speed.
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.
Fiber-Optic Light Icon - Spins when the
wheel is on; stands still when wheel is off.
Heat Icon - Indicates different stages of heating.

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

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 “ ” icon will display until
the mode is changed.
Economy mode heats the spa to set temperature only
during filter cycles. The “ ” icon will display
until mode is changed.
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.
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.

Preset Filter Cycles
On all systems, the pump and the ozone generator will
run during filtration. At the start of each filter cycle, the
blower will run briefly on its highest speed to purge the
air channels. The lowest speed of any other pumps and
the mister will also run briefly. On some circ systems,
pump 1 may also run for the duration of the filter.
(The following is specific to all systems that are
programmed according time)
There are two filter cycles per day. The start/end
times of each cycle are programmable. To program,
set time as instructed above, then press “Mode/Prog”
to advance to the next setting (or to exit after the last
setting). Default filter cycles can vary from system to
system. A common default is 8:00 AM to 10:00 AM and
8:00 PM to 10:00 PM. Press “Time” then “Mode/Prog”
to step through the filter settings to see how they are
currently set.
Each filter cycle automatically operates the pump for the
duration of the filter cycle. The filter 1 “F1 ” icon will
light when filter 1 is running. The filter 2 “F2 ” icon
will light when filter 2 is running.
(The following is specific to EL2000 and EL1000
systems that are programmed according to
duration rather than time)
The first filter cycle (“day”) begins 6 minutes after the
spa is powered up. The second filter cycle (“night”)
begins 12 hours later. Filter duration is programmable for
1-12 hours (“”-“ ”). The default filter duration can
vary from system to system. To program, press “Warm”
or “Cool,” then “Jets 1.” Press “Warm” or “Cool” to select
the filter duration. Press “Jets 1” to select the number
of filter cycles. The display will show “ ” (both “day”
and “night” cycles); “ ” (day cycle only); or “ ” (“night”
cycle only). Press “Warm” or “Cool” to adjust, then press
“Jets 1” to exit the programming mode. For continuous
filtration, use “ ” and “ ”.
Note: EL1000 and some EL2000 systems are capable of
being programmed by time rather than by duration (see
Preset Filter Cycles section). On EL2000 and EL1000
systems with duration programming only, the spa powers
up at 12:54, thus the first filter cycles begins 6 minutes
later at 1:00. If you would like your spa to begin filtering
at another time, you may change the clock to align with
your preferred filter time, rather than the actual time
of day.
Optional Filter Cycle Programming
You are not required to set filter cycles; however,
it is an option available to you. To change the filter
cycle settings:
Press “Time” “Mode/Prog” “Mode/Prog” “Mode/Prog”
within 3 seconds. You will see the “ ”
and a flashing “ ” icon appear on the display.
Press “Up” or “Down” to choose the filter start time
hour. Enter the hour by pressing “Mode/Prog”.Press
“Up” or “Down” to choose the filter start time minutes.
Each press changes the start time by 5 minutes.
Enter the minutes by pressing “Mode/Prog.”
Press “Mode/Prog” to see “ ” and
a flashing “ ” icon. Adjust the time as
done above.
Press “Mode/Prog” to see the “ ”
(PM cycle) and a flashing “ ” icon. Proceed
as above.
Press “Mode/Prog” to see “ ” and
a flashing “ ” icon. Adjust the time as
done above.
Pressing “Mode/Prog” will enter the new filter
cycle times into the system and display the current
water temperature.
Pressing “Time” at any time during this programming
sequence will save the values entered up to that point
and exit programming.
If you would like to select continuous filtration, set the
filter 1 start and end times to be the exact same time.
In this case, the filter 2 start time only controls when
the second purge happens. Filter 2 end time will
be unavailable.

Light
Some systems are equipped with both a spa light and a
fiber optic light; however, only one can be accessed by this
panel. (Larger panels may be purchased so that both the
spa light and fiber optic light can be utilized.) Depending
upon how your spa is equipped and configured, the
“Light” button will operate in one of three ways:
1) Press the “Light” button to turn the spa light on and
off, and to shift between dim and bright settings if your
light is dimmable. On dim, the LCD will show 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.
2) If a fiber-optic light with wheel is installed, press the
“Light” button once to start the light and wheel, press
it again to stop the wheel, and then again to turn the
light off. The fiber icon stands still when the fiber optic
light is on by itself, and rotates when the color wheel is
also on.
3) If a fiber-optic light without a separate wheel stop is
installed, press the “Light” button to turn it on and off.
Again, both a spa light and a fiber optic light may be
used simultaneously on the EL8000 and EL5000 systems
with a different panel.
If any light is left on, it will automatically turn off after a
factory programmed time period.
Option (optional)
Press the “Option” button to turn optional equipment
(such as TV or Stereo) on and off (with no timeout).
Fiber (optional on some systems)
If a fiber-optic light with wheel is installed, press the
“Fiber” button once to start the light and wheel, press
it again to stop the wheel, and then again to turn the
light off. The fiber icon stands still when the fiber-optic
light is on by itself, and rotates when the color wheel is
also on.
Both spa light and fiber-optic light can be used
simultaneously on systems that have both. If either light
is left on, it will automatically turn off after a timeout
period (on some systems this timeout can be as long as
4hours.)
Use the “Light” button if your fiber-optic system is on/off
only (no separate wheel stop).
Freeze Protection
If the temperature sensors within the heater detect a low
enough temperature, then the pumps and the blower
automatically activate to provide freeze protection. The
equipment stays on for at least 4 minutes, and until the
sensors detect that the spa temperature is warm enough.
In colder climates, an optional additional freeze sensor
may be added to protect against freeze conditions that
may not be sensed by the standard sensors. Auxiliary
freeze sensor protection acts similarly except with the
temperature thresholds determined by the switch and
without a 4-minute delay in turnoff. See your dealer
for details.
Locking the Panel
Press “Time” “Jets 1” then “Warm” within 3 seconds.
When locked, the PL “PL ” light will light. All buttons
are frozen except the “Time” button. To unlock the
panel, press “Time” “Jets 1” then “Cool.”
Locking the Set Temperature
Press “Warm” or “Cool” then “Time,” “Jets 1,” and
“Warm” within 3 seconds to activate the lock. The
TL “TL ” light will light when the set temperature
is locked.
On some systems, locking the set temperature also locks
out Mode changes.
To unlock the set temperature, press “Warm” or “Cool”
then “Time,” “Jets 1” and “Cool.”
Clean-up Cycle (optional)
When a pump or blower is turned on by a button
press, a clean-up cycle begins 30 minutes after the
pump or blower is turned off or times out. The pump
and the ozone generator will run for one to four hours,
depending on the system (on some systems, you can
change this setting; see User Preferences section.)
Circ Pump (optional)
If your system is equipped with a circ pump, it may be
configured to work in one of three different ways:
1) The circ pump operates continuously (24 hours) with
the exception of turning off for 30 minutes at a time
when the water temperature reaches 3°F (1.5°C) above
the set temperature (most likely to happen in very
hot climates).
2) The circ pump stays on continuously, regardless of
water temperature.
3) The circ pump will come on when the system is
checking temperature (polling), during filter cycles,
during freeze conditions, or when another pump is on.
Page 4
Note: If your spa has additional functions not listed
here, please refer to the section Optional Auxiliary
Panels as listed in the Table of Contents.

Page 5
Ozone (optional)
On most systems, the ozone generator (if installed) runs
during filter cycles (except when pump 1 is operating at
high speed on a non-circ system) and during clean-up
cycles. On some systems, the ozone generator operates
whenever the pump runs.
If your system is configured with the optional ozone
suppress feature, the ozone generator will turn off for
1 hour any time a function button (Jets 1, Jets 2, Blower,
etc.) is pressed.
Displaying Information About Your Spa
There are several pieces of information about your
spa that can be called up from the panel, but are only
needed in special cases.
To access this information, press “Warm” or “Cool”
then “Jets 1”, then “Light”. (Each press must be within
3 seconds of the previous press.) Then press “Temp”
until you see “ ” on the display. Press “Jets 1” to see
the SSID (a series of 3 numbers, such as 100 133 10,
which indicates the precise revision of the software
in your spa), followed by the Mach software version
number (such as 2.1), followed by “ ” and then your
spa’s network ID number (consisting of both letters and
digits displayed in 4 steps).
If you need to see this series of numbers again,
and “ ” is once again on the display, just press
“Jets1”again.
When done, press the “Light” button (more than once if
necessary) until you see the normal temperature display.
User Preferences
There are several aspects of spa operation that you can
customize using the User Preferences submenu.
Press “Warm” or “Cool” then “Jets 1”, then “Light”. (Each
press must be within 3 seconds of the previous press.)
At this point, if “ ” is not showing on the display,
press “Temp” until you see “ ” on the display. Then
press “Jets 1” to enter the User Preferences submenu.
Once in the User Preferences submenu, press “Warm” or
“Cool” to cycle between these settings:
– Suppress Reminders
When set to “ ”, reminders are never displayed
on the panel. When set to “ ”, reminders are
displayed on the panel periodically.
– Temperature in Celsius
When set to “ ”, temperatures are displayed on
the panel in degrees Celsius. When set to “ ”,
temperatures are displayed in Fahrenheit.
– 24-hour Time Display
When set to “ ”, time is displayed in 24-hour
(military) format (00:00 is midnight, 23:00 is one
hour before midnight). When set to “ ”, time
is displayed in 12-hour (am/pm) format (12:00 is
midnight, 11:00 pm is one hour before midnight).
– Clean-up Cycle Duration (some systems only)
When set to “ ”, Clean-up Cycles are disabled.
When set to “ ” through “ ”, the number
indicates how many hours each Clean-up Cycle
will run.
Editing User Preferences
View the setting.
The left two characters (before the decimal point) tell
you what setting you’re viewing or editing, the right most
character (after the decimal point) tells you the value of
that setting (for example, “ ” for Yes or “ ” for No).
If the value is flashing, you’re editing it. If the value is
not flashing, you’re just viewing it.
Press “Jets 1” to switch editing of the value on (flashing)
or off (not flashing).
Once you’re editing the value (it’s flashing), use the
“Warm” or “Cool” buttons to change the value to the one
you want.
After you change the value, you must press “Jets 1” again
to stop the flashing before the change will register, and
before you can view or edit another setting.
If you don’t interact with the menu for more than
30 seconds, it may time out.
If you press “Light” to back out of the menu, or pause
long enough for it to time out, while a value was
flashing, the changes you were making to that setting
are not remembered. But changes you previously made
to other settings will be in effect.
Any User Preferences that you change will stay in
effect “forever” or until you change them again (unless
the spa’s “persistent memory” is reset by a service
technician), and will override the factory defaults for
those settings.
