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 ML400
Pressing “Temp” followed by “Aux” or “Jets 2” or “Blower”
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” 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 ML400
Press the “Jets” 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 time-out period. The
pump 1 low speed time-out 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) ML400
If your system has a second pump but your panel does
not have a “Jets 2” button, use the “Aux” button to control
pump 2. 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 time-out period.
Blower (optional on some systems) ML400
If your system has a blower (and only one pump), but your
panel does not have a “Blower” button, use the “Aux” button
to control the 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 time-
out period.
Circ Pump (optional) ML400
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.
Light ML400
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.
Ozone (optional) ML400
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, Jets 2, Blower, etc.) is pressed.
