10.0 Automatic Filtration Cycles

Your new spa includes a 24-hour circulation pump which filters the
water continuously. The circulation pump draws water through the
skimmer bag and one of two filter cartridges to effectively remove small
debris in your spa. Note: the 24-hour circulation pump system also sup-
plies heated water to the spa when the heater turns on. This features
cannot be altered or disabled.
The control system activates a programmable "standard" or "economy"
skimming/heating cycle to remove larger debris missed by the 24-hour
circulation pump filtration system. These cycles utilize pump # and the
filter cartridge to quickly clear "skim" the water of large debris and mini-
mize their "bath-tub ring" effect. Apart from their skimming benefit, each
mode also effects the operation of your spa's heater. Refer to sections
0. and 0.2 below for additional information.
10.1 Standard Skimming/Heating Modes (F0 - F3)
Standard skimming/heating modes are typically selected by customers
in cold climates where heat up times are extended due to lower ambi-
ent temperatures. In 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 operate 24-
hours to filter and clean your spa.
10.2 Economy Skimming/Heating Modes (F4 - F6)
Economy skimming/heating modes are typically selected by custom-
ers in warm climates where heat up times are minimized due to higher
ambient temperatures. In these modes, the water temperature is regu-
lated by the set temperature, 24-hour circulation pump, and heater only
while a programmed filter cycle is running (unless in summer logic; see
section 3., page 34). Note: these modes consume less energy than
standard modes F0-F3 outlined above.
10.3 Lock Modes (L1 - L2)
These modes are designed for use during spa service or to prevent
unauthorized use.
