Initial Start-up
When your spa is first actuated, it will go into Priming mode, indicated by “ .” Please see the M-7 Installation Instruction
Manual for complete instructions on Power-up and Pump Priming. The Priming mode will last for less than 5 minutes and
then the spa will begin to heat the spa and maintain the water temperature in the Standard mode.

Temp/Set (80°F - 104°F / 26°C - 40°C)
Mode is changed by pressing the “Temp” or “Set” button,
then pressing the “Light” button.
The start-up temperature is set at 100F°/37°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.
To display the set temperature, press the “Temp” or “Set”
pad once.
To change the set temperature, press the pad a second
time before the LCD stops flashing. Each press of the
“Temp” or “Set” pad will continue to either raise or
lower the set temperature.
If the opposite direction is desired, release the pad and
let the display revert to the current water temperature.
Press the pad to display the set temperature, and again
to make the temperature change in the desired direction.
After three seconds, the LCD will stop flashing and
display the current spa temperature.
Standard Mode is programmed to maintain 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. “ ” will be displayed
momentarily when you switch into Standard Mode.
Economy Mode heats the spa to the set temperature
only during filter cycles. “ ” will display solid when
temperature is not current, and will alternate with
temperature when temperature is current.
Sleep Mode heats the spa to within 20°F of the set
temperature only during filter cycles. “ ” will display
solid when temperature is not current, and will alternate
with temperature when temperature is current.
Preset Filter Cycles
The first filter cycle begins 6 minutes after the spa is
energized. The second filter cycle begins 12 hours later.
Filter duration is programmable for 2, 4, 6, 8 hours or for
continuous filtration (indicated by “ ”). The default filter
time is 2 hours.
To program, press “Temp” or “Set,” then “Jets.”
Press “Temp” or “Set” to adjust. Press “Jets” to
exit programming.
The blower purges for 30 seconds at the beginning of
each filter cycle. The low speed of the pump runs during
filtration and the ozone generator (if installed) will
be enabled.
Jets
Touch the “Jets” button once to activate the low speed
of the pump and again for the high speed. Press the
“Jets” button again to turn off the pump. If left running,
the low speed of the pump will automatically turn off
after 4 hours, and the high speed will automatically
turn off after 15 minutes. The low speed of the pump
runs when the blower is on. It may also activate for
at least 2 minutes every 30 minutes to detect the spa
temperature 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.
Freeze Protection
If the temperature sensors detect a drop to below
45°F within the heater, the pump and blower will
automatically activate to provide freeze protection. The
equipment stays on until 4 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. Aux
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.
Jets 2
This button is used to turn pump 2 on and off. If left on,
the pump automatically turns off after 15 minutes.
Light
Press the “Light” button to turn the light on and off. If
left on, the light automatically turns off after 4 hours.

The control panel will be disabled until power returns.
Spa settings will be preserved until next power up.
Temperature unknown.
After the pump has been running for 2 minutes, the
temperature will be displayed.
“Overheat” - The spa has shut down. One
of the sensors has detected 118°F at the
heater.
DO NOT ENTER THE WATER. Remove the spa cover
and allow water to cool. Once the heater has cooled,
reset by pushing any button. If spa does not reset,
shut off the power to the spa and call your dealer or
service organization.
“Overheat” - The spa has shut down. One
of the sensors has detected that the spa
water is 110°F.
DO NOT ENTER THE WATER. Remove the spa
cover and allow water to cool. At 107°F, the spa
should automatically reset. If spa does not reset,
shut off the power to the spa and call your dealer or
service organization.
“Ice” - Potential freeze condition detected.
No action required. The pump and blower will
automatically activate regardless of spa status.
Spa is shut down. The sensor that is
plugged into the Sensor “A” jack is
not working.
If the problem persists, contact your dealer or service
organization. (May appear temporarily in an overheat
situation and disappear when the heater cools.)
Spa is shut down. The sensor that is
plugged into the Sensor “B” jack is
not working.
If the problem persists, contact your dealer or service
organization. (May appear temporarily in an overheat
situation and disappear when the heater cools.)
Sensors are out of balance. If alternating
with spa temperature, it may just be a
temporary condition. If flashing by itself,
spa is shut down.
If the problem persists, contact your dealer or
service organization.
A significant difference between
temperature sensors has been detected.
This could indicate a flow problem.
Check water level in spa. Refill if necessary. If the
water level is okay, make sure the pumps have been
primed. If problem persists, contact your dealer or
service organization.
Persistent low flow problems. (Displays on
the fifth occurrence of “ ” message within
24 hours.) Heater is shut down, but other
spa functions continue to run normally.

capability of the spa will not reset automatically; you
may press any button to reset.
