Freeze Protection; Clean Up Cycle - Cal Spas LTR20101000 Owner's Manual

16
The "FILTER 1" indicator icon will light when filter
1 is running.
• The second filter cycle is automatically activated
at 8:00 PM and operates the pump until 10:00 PM.
The "FILTER 2" indicator icon will light when filter
2 is running.
The pump and the ozone generator will run during
filtration. At the start of each filter 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 five minutes. In the event of power
loss or shut down, the time of day will need to be
reset for filter 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 filter cycles (except
when pump 1 is operating at high speed on a non-circ
ulating 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 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.
