Circulation Pump Modes
The circ pump (if your spa is equipped with
one) operates continuously (24 hours) with
the exception of turning o 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 very hot climates).
Filtration and Ozone
On non-circ systems, Pump 1 low and the
ozone generator will run during ltration. On
circ systems, the ozone will run with
the circ pump.
The system is factory-programmed with
one lter cycle that will run in the evening
(assuming the time-of-day is properly
set) when energy rates are often lower. The
lter time and duration are programmable. A
second lter cycle can be enabled as needed.
At the start of each lter cycle, the blower (if
there is one) or Pump 2 (if there is one) will run
briey to purge its plumbing to maintain good
water quality.
Freeze Protection
If the temperature sensors within the heater
detect a low enough temperature, the
pump(s) and the blower automatically
activate to provide freeze protection.
The pump(s) and blower will run either
continuously or periodically depending
on conditions.
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. See your dealer for details.
Clean-up Cycle (optional)
When a pump or blower is turned on by a
button press, a clean-up cycle begins 30
minutes after the pump or blower is
turned o or times out. The pump and the
ozone generator will run for 30 minutes or
more, depending on the system. On
some systems, you can change this setting.
TEMPERATURE & TEMP RANGE
Adjusting the Set Temperature
Pressing Up or Down temperature buttons
will cause the temperature to ash. Pressing a
temperature button again will adjust the set
temperature in the direction indicated on the
button. When the LCD stops ashing, the spa
will heat to the new set temperature.
Press-and-Hold
If a Temperature button is pressed and
held when the temperature is ashing, the
temperature will continue to change
until the button is released.
Dual Temperature Ranges
This system incorporates two temperature
range settings with independent set
temperatures. The High Range designated in
the display by an “up” arrow, and the Low
Range designated in the display by a “down”
arrow. These ranges can be used for various
reasons, with a common use being a “ready to
use” setting vs. a “vacation” setting.
The Ranges are chosen using the menu
structure below. 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.
For example:
High Range may be set between 80°F - 104°F.
Low Range may be set between 50°F - 99°F.
Freeze Protection is active in either range.
