DIP Switches and Jumpers Definitions
DIP Switchbank A Key
A1 ................Test Mode (normally Off)
A2 ................In “ON” position, heater can run while any/all high-speed pumps or blowers are running
  (High amperage)
 ................In “OFF” position, heater is disabled while any high-speed pump or blower is running
  (Low amperage)
A3 ................In “ON” position, filter cycles are programmed by duration for non-time capable panels
 ................In “OFF” position, filter cycles are programmed to start and end times for time capable panels
A4* ................In “ON” position, displays time in 24 hours (military\European time)
 ................In “OFF” position, displays 12 hour time
A5* ................In “ON” position, displays temperature in Celsius
 ................In “OFF” position, displays temperature in Fahrenheit
* Sets default for user preferences - only applies when persistent memory is reset (A12 On) during power-up
A6 ................In “ON” position, Equipment timeout 30 minutes (4 hours for Pump 1-Low)
 ................In “OFF” position, Equipment timeout 15 minutes (2 hours for Pump 1-Low)
A7 ................In “ON” position, Cleanup Cycle – 30 minutes after spa use/timeout, Pump 1-Low & Ozone or 
    Circ Pump and Ozone run for 1 hour
 ................In “OFF” position, no Cleanup Cycle
A8 ................In "ON" position, Ozone suppression for one hour after pump/blower button press
A9 and A10.............See Table for Circ Pump Behavior settings
A11 ................In “ON” position
  (non-circ mode operation) Pump 1 is two-speed, Ozone is 
    ON in Filter & Cleanup Cycles only
  (in any circ mode) Pump 1 is one-speed, Ozone is ON with 
  circ pump
 ................In “OFF” position
  (non-circ mode operation) Pump 1 is two-speed, Ozone is 
    ON with Pump 1-Low
  (in any circ mode) Pump 1 is two-speed, Ozone is ON with 
  circ pump
A12 ................Persistent memory reset (normally off) (used when spa is 
  powering up)
    Circ Pump 
 A9 A10  Behavior
 OFF  OFF  No Circ Pump 
      or Circ Pump not 
    plumbed w/heater
 ON  OFF  24 Hours
 OFF  ON  24 Hr w/3°F Shut-Off
 ON  ON  Acts like Pump 1-Low
      (Filter Cycles, Polls)
Jumpers
J8  Jumper on 1 Pin only when using 2.0kW or 1.0kW heater. 
Jumper on Pins 1 and 2 when using 3.0kW heater.
J91  Jumper on 1 Pin only enables Real Time Clock function; use with time capable panels. 
Jumper on Pins 1 and 2 disables RTC function; use with non-time capable panels.
DIP Switchbank B Key
B1 ...............In “ON” position, single-speed Pump 2
 ...............In “OFF” position, two-speed Pump 2
B2 ...............In “ON” position, Pump 2 enabled
 ...............In “OFF” position, Pump 2 disabled
B3 ...............In “ON” position, Blower enabled
 ...............In “OFF” position, Blower disabled
B4 ...............In “ON” position, Fiber and Wheel instead of Spa Light
  (if A9 & A10 are both OFF, Fiber uses J2 connector; if either A9 or A10 is ON, X-FOW Kit required to run Fiber)
 ...............In “OFF” position, Spa light enabled
B5 ...............In “ON” position, Pump 3 enabled (Jets 3 replaces Blower on Aux panel)
 ...............In “OFF” position, Pump 3 disabled
B6 ...............In “ON” position, Alternate Panel layout
 (ML900 scrunching enabled - ML550 / 700 Jets 3 replaces Blower)
 ...............In “OFF” position, Normal Panel layout
WARNING:
sSetting DIP switches incorrectly may cause abnormal system behavior and/or damage to system components.
