10.0 Automatic Filtration Cycles
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”
filtration/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 “bath-tub ring” effect. Apart from their filtration ben
-
efit, each mode also effects the operation of your spa’s heater. Refer to
sections 10.1 and 10.2 below for additional information.
10.1 Standard Filtration/Heating Modes (F0 - F3)
Standard filtration/heating modes are typically selected by customers in
cold climates where heat up 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 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 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 ambi
-
ent temperatures. In these modes, the water temperature 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 13.1, page 37).
Note: these modes consume less energy than
standard modes F0-F3 outlined in section 10.1.
10.3 Lock Modes (L1 - L2)
These modes are designed for use during spa service or to prevent
unauthorized use.
