10.0 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 cus-
tomers 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, low-speed jets pump 1 and heater
which turns 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 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 cus-
tomers 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, 24 hour circulation pump and heater
which turns on as needed. After the programmed set temperature is
reached, the heater turns off and the circulation pump continues to oper-
ate 24 hours to filter and clean your spa.

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, low-speed pump, optional circulating pump and heater
only while a programmed filtration/heating cycle is running. 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 unau-
thorized use.
