11.0  Automatic Filtration Cycles
The control system activates a programmable “Standard” or “Economy” 
ltration cycle to remove debris from your spa. These cycles use the low 
speed jets pump 1 and lter cartridge to quickly clear “skim” the water of 
debris and minimize their “bathtub ring” affect while the spa is in use or 
during a programmed lter cycle. Apart from their ltration benet, each 
ltration mode also effects the operation of the spa heater. 
11.1  Standard Filtration/Heating Modes
Standard ltration/heating modes (F1-F3) are typically selected by 
customers in cold climates where heat up times are extended due to 
lower ambient temperatures. In these modes, the low-speed pump and 
heater will come on as necessary to maintain the set temperature 24 
hours a day. The low speed pump will run continuously during the ltration/
heating cycles with the heater coming on as necessary to maintain the set 
temperature.
11.2  Economy Filtration/Heating Modes (All Models)
Economy ltration/heating modes (F4-F6) 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 only during a programmed ltration/
heating cycle. The heater will turn on only when there is a heat call 
during a programmed ltration/heating cycle.
Note: These modes can be used to conserve energy while on vacation 
or out of town for several weeks since heater operation is minimized. 
During such times, you can also minimize the spa set temperature to 
maximize energy savings!
11.3  Lock Modes - L1-L2 (All Models)
These modes are designed for use during spa service or to prevent 
unauthorized use.
11.4  Selecting The Filtration/Heating Mode
Press and hold both control panel WARMER ( ) and COOLER ( ) 
buttons at the same time, then release. Then press either WARMER 
( ) or COOLER ( ) button to select either ltration/heating mode or 
lock mode as outlined below.
