Spa Behaviour
Pumps
On the Spa Screen, select a “Jets” button once to turn the pump on or off, and to shift between low- and
high-speeds if equipped. If left running, the pump will turn off after a time-out period.
Non-Circ Systems
The low-speed of pump 1 runs when the blower or any other pump is on. If the spa is in Ready Mode (See
page 9), Pump 1 low may also activate for at least 1 minute every 30 minutes 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.
Circulation Pump Modes
If the system is equipped with a circ pump, it will be configured to work in one of three different ways:
1, The circ pump operates continuously (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 very
hot climates).
2, The circ pump stays on continuously, regardless of water temperature.
3, A programmable circ pump will come on when the system is checking temperature (polling), during filter
cycles, during freeze conditions, or when another pump is on.
The specific Circulation Mode that is used has been determined by the Manufacturer and cannot be
changed in the field. Other device options may be available, like Blower, Light, Mister, etc.
Filtration and Ozone
On non-circ systems, Pump 1 low and the ozone generator will run during filtration. On circ systems, the
ozone will generally run with the circ pump, but can be limited to filtration cycles. (On some circs systems,
Pump 1 low will run along with the circ Pump during filtration.)
The system is 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 time and duration are programmable.
(See page 13) A second filter cycle can be enabled as needed.
At the start of each filter cycle, the water devices like blower, mister device (if these exist) and other pumps
will run briefly to purge the plumbing to maintain good water quality.
Freeze Protection
If the temperature sensors within the heater detect a low enough temperature, then the water devices
automatically activate to provide freeze protection. The water devices will run either continuously or
periodically depending on conditions.
In colder climates, an optional 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 off 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. (See the Preferences section
on page 18)
Time-of-Day
Be sure to set the Time-of-Day
Setting the time-of-day is important for determining filtration times and other background features.
“Set Time” will appear on the display if no time-of-day is set in the memory.
On the Settings Screen, select the Time-of-Day line. On the Time-of-Day screen, simply select the
Hour, Minutes, and 12/24 Hour segments. Use the Up and Down Buttons to make changes.
