ML500, 551, 554
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.
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”). Then press any other
button to exit. System reverts 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 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)
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
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.
