9.0 Automatic Filtration Cycles
Your new spa includes a programmable 24-hour circulation pump which
filters the water continuously while using less energy than a common 100
watt light bulb! The circulation pump draws water through the smaller
MicroClean
TM
filter cartridge and effectively removes small debris in your
spa. Note: the 24-hour circulation pump system also supplies heated water
to the spa when the heater turns on. See page 26 for programming
details.
The control system activates a programmable “standard” or “economy”
skimming/heating cycles to remove larger debris missed by the 24-hour cir-
culation pump filtration system. These cycles utilize pump#1 and the larger
filter cartridge end to quickly clear “skim” the water of large debris and
minimize their “bath-tub ring” effect. Apart from their skimming benefit,
each mode also effects the operation of your spa’s heater. Refer to sec-
tions 9.1 and 9.2 below for additional information.
9.1 Standard Skimming/Heating Mode
Standard skimming/heating mode is typically selected by customers in cold
climates where heatup times are extended due to lower ambient tempera-
tures. In this mode, the water temperature is regulated by the set tempera-
ture, 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
(unless programmed otherwise).
9.2 Economy Skimming/Heating Mode
Economy skimming/heating mode is typically selected by customers in
warm climates where heatup times are minimized due to higher ambient
temperatures. In this mode, the water temperature is regulated by the set
temperature, 24-hour circulation pump, and heater only while a
programmed skimming/heating cycle is running (unless in summer logic;
see note below). Note: this mode consumes less energy than the standard
mode outlined above.
9.3 Selecting Standard or Economy Skimming/Heating Mode
Press the MODE button to select either “Standard” or “Economy” skim-
ming/heating mode. The control panel’s indicator on the right side of the
LCD changes to indicate which mode is selected. When an automatic
skimming/heating cycle activates, the LCD screen displays the following
message:
