Automatic Filtration Cycles

The control system activates a programmable "Standard" or "Economy"
filtration cycle to remove debris from your spa. These cycles use the low
speed pump, skimmer basket, and filter cartridge quickly clear "skim"
the water of debris and minimize their "bathtub ring" affect. Apart from
their filtration benefit, each mode also effects the operation of your spa's
heater. Refer to Sections 10.1-10.3 below for additional information.
10.1 Standard Filtration/Heating Modes For Models Without
Circulation Pump Option
Standard filtration/heating modes (F1-F3) are typically selected by
customers in cold climates where heat up times are extended due
to lower ambient temperatures. In either of these modes, the set
temperature regulates the water temperature. The low-speed jets pump
1 and heater turn on as needed. After the programmed set temperature
is reached, the heater and low speed pump turn off; only to turn back on
during a heat call and/or during the next programmed filtration/heating
cycle.
10.2 Standard Filtration/Heating Modes For Models With
Circulation Pump Option
Standard filtration/heating modes (F0-F3) are typically selected by
customers in cold climates where heat up times are extended due
to lower ambient temperatures. In either of these modes, the water
temperature is regulated by the set temperature. The 24-hour circulation
pump and heater turn on as needed.
10.3

Economy Filtration/Heating Modes (F4-F6)

Economy filtration/heating modes are typically selected by customers in
warm climates where heat up times are minimized due to higher ambient
temperatures. In these modes, the water temperature is regulated by the
set temperature only during a programmed filtration/heating cycle. The
heater will turn on only when there is a heat call during a programmed
filtration/heating cycle.
Note: These modes consume less energy than standard modes F1-F3
outlined above.
10.4

Lock Modes (L1-L2)

These modes are designed for use during spa service or to prevent
unauthorized use.
