Non-Circ
Operation (one pump version)
Initial Start-up
When your spa is first actuated, it will go into Priming mode,
indicated by "Pr". 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
normal operation in Standard mode. |
Temp/Set (80°F - 104°F / 26°C - 40°C)
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.
Press the "Warm" or "Cool" button to display and adjust the set
temperature. After three seconds, the LCD will automatically display
the last measured spa temperature.
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 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.
Note: The pump can also be activated by an optional
auxiliary button.
Light
Press the "Light" button to turn the spa light on and off. If
left on, the light automatically turns off after 4 hours.
If a fiber optic light 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.
Blower
This button turns
the blower on and off. The blower automatically turns off after 15
minutes. |
Mode
This button is used to switch between Standard, Economy, and Sleep
Modes.
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. "St"
will be displayed momentarily when you switch into Standard Mode.
Economy Mode heats the spa to the set temperature only during filter cycles. "Ec"
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/11°C of the set temperature only during filter cycles. "SL"
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 "FC").
The default filter time is 2 hours.
To program, press "Warm" or "Cool," then "Jets." Press "Warm" or
"Cool" 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 sterilizer (if installed) will be enabled.
Freeze Protection
If the temperature sensors detect a drop to approximately
44°F/6.7°C within the heater, then the pump and the 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 approximately 45~F ~.2:C 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.

Message |
Meaning |
Action Required |
|
No message on display.
Power has been cut off to the spa.
|
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/47.8 °C 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/43.3°C.
|
DO
NOT ENTER THE WATER. Remove the spa cover
and allow water to cool. At 107°F/42°C, 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 "HL." message within 24 hours.)
Heater is shut down, but other spa functions
continue to run normally.
|
Follow action required for "HFL" message. Heating
capability of
the spa will not reset automatically; you may press any
button to reset. |
|
Inadequate water detected in
