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 heat-
er. Refer to sections 0. and 0.2 below for additional information.

10.1 Standard Filtration/Heating modes (F1 - 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, low-speed pump, and heater which turns on as needed.
After the programmed set temperature is reached, the heater and pump
turn off, only to turn back on at the next programmed filtration/heating
cycle or during a heat call.

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 ambient
temperatures. In these modes, the water temperature is regulated by the
set temperature, low-speed 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.

10.3 Lock modes (L1 - L2)

These modes are designed for use during spa service or to prevent
unauthorized use.
