J-300 Series
11.0 automatic Filtration Cycles
Your new spa includes a 24-hour circulation pump which filters the water
continuously. The circulation pump draws water through the skimmer bag
and one of two filter cartridges to effectively remove small debris in your
spa.
note: The 24-hour circulation pump system also supplies heated water
to the spa when the heater turns on.
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 low
speed and the second filter cartridge to quickly “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 sections 11.1 and 11.2 below for additional information.
11.1 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 unless in summer logic; see section 14.1, page 38.
11.2 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, 24-hour circulation pump, and heater only while a
programmed filter cycle is running (unless in summer logic; see section
14.1, page 38).
11.3 lock modes (l1-l2)
These modes are designed for use during spa service or to prevent
unauthorized use.
11.4 selecting the Filtration/heating Mode
