MODE
Mode is changed by pressing
Temp
, then
Light
(repeat this button sequence to continue rotating
through the modes).
Standard Mode
is programmed to continuously maintain the desired temperature. Note that the
last measured spa temperature displayed is current only when the low speed of Pump 1 has
been running for at least 1-2 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 when
water temp is not current, and will alternate with water temp when the pump is running. Using
Economy Mode is not recommended in below freezing temperatures.
Sleep Mode
If the spa is not going to be used for prolonged period of time, consider using this
mode, which heats the spa to within 20°F/10°C of the set temperature only during filter cycles.
“SL” will display when water temp is not current and will alternate with water temp when the
pump is running. Using Sleep Mode is not recommended in below freezing temperatures.
PRESET FILTER CYCLES
The first preset filter cycle begins 6 minutes after the spa is energized. The second preset filter cycle
begins 12 hours later. Filter duration is programmable for 2, 4, 6, or 8 hours or for continuous
filtration (indicated by “FC” ). The default filter time is 2 hours for non-circulation systems and 4
hours for circulation systems.
To program, press

SPA BEHAVIOR
For non-circulation systems
, low-speed Pump 1 and the ozone generator (if installed) will run
during filtration.
For 24 hour circulation systems
, the circulation pump and the ozone generator (if installed) runs
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 warm climates or if set
temperature is lowered/set below the current water temperature).
Purge Cycles
In order to maintain sanitary conditions, as well as protect against freezing, all pumps
will purge water from their respective plumbing by running briefly at the beginning of each filter
cycle. It is best that all jets be left in their open position and water diverters in their centered
positions when done using the spa so all jets get water flow during purge cycles.
Automatic Polling (in Standard Mode only)
The pump will activate for 1 to 2 minutes to check the temperature every 30 minutes, whenever
any other pump is turned on, and whenever the set temperature is raised.
FREEZE PROTECTION
If the temperature sensors detect a drop to below 44°F (6.7°C) within the heater, the pump 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 (7.2°C) or higher. During freeze
protection the heater may not be activated.
