9.7 Filtration Options
Your new spa includes a 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 short side
of the double-ended 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. 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#1 and the larger filter cartridge end to quickly clear
“skim” the water of large debris and minimize their “bathtub ring”
effect. Apart from their skimming benefit, each mode also effects
the operation of your spa’s heater. Refer to sections 9.8 and 9.9
below for additional information.
9.8 Standard Skimming/Heating Modes (F0 - F3)
Standard skimming/heating modes are typically selected by custom-
ers in cold climates where heatup times are extended due to lower
ambient 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 tem-
perature is reached, the heater turns off and the circulation pump
continues to operate 24-hours to filter and clean your spa.
9.9 Economy Skimming/Heating Modes (F4 - F6)
Economy skimming/heating modes are typically selected by custom-
ers in warm climates where heatup times are minimized due to
higher ambient temperatures. In these modes, the water tempera-
ture is regulated by the set temperature, 24-hour circulation pump,
and heater only while a programmed filter cycle is running (unless in
summer logic; see section 11.1, page 24).
Note: these modes
consume far less energy than standard modes F0-F3 outlined
above.
9.10 Lock Modes (L1 - L2)
These modes are designed for use during spa service or to prevent
unauthorized use.
