Circulation Pump
This is an optional feature. The circulation pump will
come on when the system is checking temperature,
during lter cycles, during freeze conditions, or when
another pump is on.
Preset Filter Cycles
There are two lter cycles per day. The start and end
times of each cycle are programmable. To program,
set the time as instructed above, then press “MODE/
PROG” to advance to the next setting (or to exit
after the last setting). The default lter cycles are as
follows:
The rst lter cycle is automatically activated at •
8:00 AM and operates the pump until 10:00 AM.
The “FILTER 1” indicator icon will light when lter
1 is running.
The second lter cycle is automatically activated •
at 8:00 PM and operates the pump until 10:00 PM.
The “FILTER 2” indicator icon will light when lter
2 is running.
The pump and the ozone generator will run during
ltration. At the start of each lter cycle, the blower
will run on highest speed for 30 seconds to clean out
the air channels. The lowest speed of pump 2 and
pump 3 will run for ve minutes. In the event of power
loss or shut down, the time of day will need to be
reset for lter cycles to run according to your desired
programming.
Clean up Cycle
When the 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 hour.
Ozone
This is an optional feature. On most systems, the
ozone generator (if installed) runs during lter cycles
(except when pump 1 is operating at high speed on a
non-circulating system) and during clean-up cycles. On
some systems, the ozone generator operates whenever
the pump runs. If your system is congured with the
optional ozone disable feature, the ozone generator
will turn off for one hour any time a function button
(“JETS 1”, “JETS 2”, “OPTION” etc.) is pressed.
Freeze Protection
If the temperature sensors detect a drop to 44°F
within the heater, the pump automatically activates
to provide freeze protection. The equipment stays
on until four minutes after the sensors detect that
the spa temperature has risen to 45°F or higher. 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 and
without a four-minute delay in turnoff.
