Here's an excerpt on 115v/230v convertible settings:

115-230 VOLT CONVERTIBLE MODELS
• Sovereign® (Model I)
• Prodigy® (Model H)
• Jetsetter® (Model J)
230 VOLT CONVERSION INSTRUCTIONS
Refer to the following instructions to convert a 115 volt spa to a 230 volt spa.
NOTE: Converting the spa to 230 volt operation should only be done by an
authorized service agent or a qualified electrician.
Required Parts: (3) P.N. 36021 program jumpers (staged on JP jumpers in IQ 2020™
control box) and (1) P.N. 20679 or 37087 subpanel (230 volt)
1. Disconnect the power cord from the house receptacle.
2. Remove the screws and open the equipment compartment door.
3. Remove the screws on the front of the IQ 2020™ spa control box.
4. Open the control box cover.
5. Identify TB-1, located in the lower left-hand corner inside the control box.
6. Refer to Figure 1, item A. Remove both the 3 pin jumper attached to terminals 3,
4, and 5, and the 2 pin jumper attached to terminals 1 and 2.
7. Refer to Figure 1, item B. Remove the power cord wires from terminals 2, 4 and
the system ground terminal.
8. Refer to Figure 1, item C. Attach the 2 pin jumper to terminals 4 and 5.
9. Unscrew the power cord strain relief and remove the power cord from the
access hole in the control box.
10. On the large circuit board, locate the program jumpers, JP-1 through JP-12 (positioned near the center of the circuit
board, with JP-1 being the top jumper).
WARNING: Do not allow pliers to contact any electronic components inside the control box.
11. Use a pair of needlenose pliers to place the program jumpers as shown in Figure 2 (use Watkins P.N. 36021).
NOTE: The program jumpers JP-1, JP-2 and JP-3 must be set correctly for the spa to operate. Figure 2 illustrates the
correct jumper settings.
Converting from 115 volts to 230 volts changes the voltage supplied to the heater from 115 volts to 230 volts. The jet
pump will continue to operate at 115 volts.
