SPA BEHAVIOR

FILTRATION AND OZONE
If your spa does not have a circulation pump, pump
1 low and the ozone generator will run during a filter
cycle. If your spa has a circulation pump, the ozone will
run with the circulation pump.
Many control systems are factory-programmed with
one filter cycle that will run in the evening (assuming
the time-of-day is properly set) when energy rates
are often lower. The filter cycle time and duration are
programmable (view page 14). A second filter cycle can
be enabled as needed.
At the start of each filter cycle, any additional water
devices (such as pumps and blower) will also run briefly
to purge its plumbing to maintain good water quality.
FREEZE PROTECTION
If the temperature sensors within the control system's
heater detect a low enough temperature, then 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.
CLEANUP CYCLE (Optional)
When a pump or blower is turned on by pressing
a button on the panel, a clean-up cycle begins 30
minutes after the pump or blower is turned Off or times
out. The pump and the ozone generator will run for 30
minutes or more, depending on the control system.
On some control systems, you can change this setting
(view page 29).

PUMPS
Press the JETS button once to turn Pump 1 On or
Off, and to shift between low-speed and high-speed
if equipped. If left running, Pump 1 will turn Off after a
time-out period.
If your spa does not have a circulation pump, Pump
1 will run at low speed when the blower or any other
pump is on.
If the spa is in Ready Mode (view page 22), Pump 1
low may also activate for at least 1 minute every once
in a while to detect the spa temperature (polling) and
then to heat to the set temperature if needed. When
the low-speed turns on automatically, it cannot be
deactivated from the panel, however the high speed
may be started.
3 CIRCULATION PUMP MODES
If the spa is equipped with a circulation pump, it will
be configured to work in one of the following
three modes:
MODE 1: The circulation pump will operate
continuously (24 hours) with the exception of turning
Off for at least 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).
MODE 2: The circulation pump will stay on
continuously, regardless of the water temperature.
MODE 3: A programmable circulation pump will
come on when the control system is checking the
water temperature (polling), during filter cycles, during
freeze conditions, or when another pump is on.
Circulation pump modes are determined by
the Manufacturer and cannot be changed
in the field.
HOW DOES YOUR CONTROL SYSTEM
CHECK THE WATER TEMPERATURE?
The control system (A) activates a pump that
circulates water from the spa tub through the water
heater (B) shown below. The water heater contains
two temperature sensors (C). When water flows
around the sensors, the control system calculates
the water temperature. This process is referred to
as "polling" in this user guide.
HEATER PUMP
The heater pump is any pump dedicated to
circulating water through the water heater. If your
spa has a circulation pump, the circulation pump
will serve as the heater pump. If your spa does
not have a circulation pump, a two-speed pump
will serve as the heater pump. If the heater pump
is a two-speed pump, anytime it is activated
automatically (for any reason, including to check
the water temperature), it will activate at low speed.
