on, the equipment will automatically turn off after 15
minutes.
Light
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 control panel will show
the center circle plus one quarter of the light beams.
Half of the light beams will show on medium bright-
ness, and all of the light beams will show on bright.
Invert
Press the "INVERT" button to change the numbers
in the display to read upside down. Another press
returns the display to the right-side-up position. This
enables you to read the display while you are in the
spa.
Locking the Panel
To lock the panel:
• Press "TIME", "JETS 1", and the "UP" button within
three seconds. When locked, the panel will display
"LOCK". All buttons are frozen except the "TIME"
button.
To unlock the panel:
• Press "TIME", "JETS 1" then the "DOWN" button
within three seconds.
Setting the Temperature Lock
To activate the temperature lock:
• Press the "UP" or "DOWN" button, "TIME", "JETS
1", then the "UP" button within three seconds. The
panel will display "TEMP LOCK" when the set tem-
perature is locked.
To unlock the set temperature:
• Press the "UP" or "DOWN" button, "TIME", "JETS
1", and then the "DOWN" button.
Circulation Pump
This is an optional feature. The circulation pump will
come on when the system is checking temperature,
during filter cycles, during freeze conditions, or when
another pump is on.

Preset Filter Cycles

There are two filter cycles per day. The start and end
times of each cycle are programmable. To program,
set the time as instructed above, then press "MODE/
PROG" to advance to the next setting (or to exit after
the last setting). The default filter cycles are as fol-
lows:
Inground Spas
LTR20121002, Rev. A
• The first filter cycle is automatically activated at
8:00 AM and operates the pump until 10:00 AM.
The "FILTER 1" indicator icon will light when filter
1 is running.
• The second filter cycle is automatically activated
at 8:00 PM and operates the pump until 10:00 PM.
The "FILTER 2" indicator icon will light when filter
2 is running.
The pump and the ozone generator will run during fil-
tration. At the start of each filter cycle, the blower will
run on highest speed for 30 seconds to clean out the
air channels. The lowest speed of pump 2 and pump
3 will run for five minutes. In the event of power loss
or shut down, the time of day will need to be reset for
filter cycles to run according to your desired program-
ming.
Clean-up Cycle
When the 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 hour.
Ozone
This is an optional feature. 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 op-
tional ozone disable feature, the ozone generator will
turn off for one hour any time a function button ("JETS
1", "JETS 2", "OPTION" etc.) is pressed.

Freeze Protection

If the temperature sensors detect a drop to 44°F
within the heater, the pump automatically activates
to provide freeze protection. The equipment stays
on until four minutes after the sensors detect that
the spa temperature has risen to 45°F or higher. 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 four-minute delay in turnoff.
