Balboa Water Group ML550 User Guide - Manual (Page 4)

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 1 minute.
Cool/Warm
Press the “Cool” or “Warm” 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
This button is used to switch between Standard,
Economy, and Sleep modes. Press “Mode” to enter mode
programming, press “Cool” to cycle through to desired
mode (LCD flashes until confirmed), then press “Mode”
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 1 minute. “
” will appear on the display
momentarily when you switch into Standard Mode.
Economy mode heats the spa to the set temperature
only during filter cycles. “
” will appear solid when
the temperature is not current and will alternate with the
temperature when the temperature is current.
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. During this time, pressing
“Cool” or “Warm” followed by “Light” will revert the
mode to Economy immediately.
Sleep mode heats the spa to within 20°F (11°C) of the
set temperature only during filter cycles. “
” will
appear on the display until mode is changed.
Standby Mode
Pressing “Cool” or “Warm” followed by “Blower”
or “Jets 2” or “Aux” will turn off all spa functions
temporarily. This is helpful when changing a filter.
Pressing any button exits Standby mode. 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 1 minute 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.
Jets 2 (optional on some systems)
Press the “Jets 2” button once to turn pump 2 on or
off, and to shift between low and high speeds if it is
a two-speed pump. If left running, the pump will turn
off after a timeout period.
Blower
1-speed operation: on/off;
2-speed operation: med/hi/off; or
3-speed operation: lo/med/hi/off.
If left on, the blower will automatically turn off after a
timeout period.
Note: If your system does not have a “Blower” button, and
is labeled as ”Jets 3” instead, please see page 9 “Jets 3”.
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.
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.
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.
