Preset Filter Cycles
On all systems, the pump and the ozone generator will
run during filtration. At the start of each filter cycle, the
blower will run briefly on its highest speed to purge the
air channels. The lowest speed of any other pumps and
the mister will also run briefly. On some circ systems,
pump 1 may also run for the duration of the filter.
(Note: This panel cannot be used to program filter
cycles for systems that are programmed by time
rather than by duration. For these systems, a larger
panel is needed and the following description does
not apply.)
The first filter cycle (“day”) begins 6 minutes after the
spa is powered up. The second filter cycle (“night”)
begins 12 hours later. Filter duration is programmable for
1-12 hours (“
”-“ ”). The default filter duration can
vary from system to system. To program, press “Cool” or
“Warm,” then “Jets 1.” Press “Cool” or “Warm” to select
the filter duration. Press “Jets 1” to select the number
of filter cycles. The display will show “
” (both “day”
and “night” cycles); “ ” (day cycle only); or “ ” (“night”
cycle only). Press “Cool” or “Warm” to adjust, then press
“Jets 1” to exit the programming mode. For continuous
filtration, use “
” and “ ”.
Freeze Protection
If the temperature sensors within the 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.
Locking Features
If this panel is used as the main panel, locking features
will not be available.
If this panel is used as a remote or additional panel, it
will lock when the main panel is locked. To unlock this
panel, unlock the main panel.
In the same way, the set temperature can be locked and
unlocked by a main panel. When the set temperature is
locked, it cannot be changed from either panel.
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 one to four hours,
depending on the system (on some systems, you can
change this setting; see User Preferences section.)
Circ Pump (optional)
If your system is equipped with a circ pump, it may 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) The circ pump will come on when the system is
checking temperature (polling), during filter cycles,
during freeze conditions, or when another pump is on.
Ozone (optional)
On most systems, the ozone generator (if installed) runs
during filter cycles (except when pump 1 is operating at
high speed on a non-circ system) and during clean-up
cycles. On some systems, the ozone generator operates
whenever the pump runs.
If your system is configured with the optional ozone
suppress feature, the ozone generator will turn off for
1 hour any time a function button (Jets 1, Jets 2, Blower,
etc.) is pressed.
