The Lock option can be accessed from the “ Settings ” menu.
SETTINGS
The Settings Screen is where all programming and other spa
behaviors are controlled. This screen has several features that
can be acted on directly. These features may include Temp
Range, Heat Mode, Hold, and Invert Panel. When one of these
items is selected, it will toggle between two settings. All other
menu items (with an arrow pointing to the right) go to another
level in the menu.
DUAL TEMPERATURE RANGES (HIGH VS. LOW)
This system incorporates two temperature range settings with
independent set temperatures. The specific range can be
selected on the Settings screen and is visible on the Main
Screen in the upper right corner of the display. These ranges
can be used for various reasons, with a common use being a
“ready to use” setting vs. a “vacation” setting. Each range
maintains its own set temperature as programmed by the user.
This way, when a range is chosen, the spa will heat to the set
temperature associated with that range.

High Range can be set between 80°F and 104°F.

Low Range can be set between 50°F and 99°F.
HEAT MODE – READY VS. REST
In order for the spa to heat, a pump needs to circulate water
through the heater. The pump that performs this function is
known as the “heater pump.” The heater pump can be either a 2-
speed pump (Pump 1) or a circulation pump. If the heater pump
is a 2-Speed Pump 1, Ready Mode will circulate water every 1/2
hour, using Pump 1 Low, in order to maintain a constant water
temperature, heat as needed, and refresh the temperature
display. This is known as “polling.” Rest Mode will only allow
heating during programmed filter cycles. Since polling does not
occur, the temperature display may not show a current
temperature until the heater pump has been running for a minute
or two. When the heater pump has come on automatically (for
example for heating) you can switch between low speed and
high speed but you cannot turn the heater pump off.
RESTRICTING OPERATION
The control can be restricted to prevent unwanted use or
temperature adjustments. Locking the Panel prevents the
controller from being used, but all automatic functions are still
active. Locking the Settings allows Jets and other features to be
used, but the Set Temperature and other programmed settings
cannot be adjusted. Settings Lock allows access to a reduced
selection of menu items. These include Filter Cycles, Invert,
