This guide will help you to wire a 2-speed 230v motor to a Hayward Pro Logic. Before you start, you must ensure that the electrical supply agrees with the motor's voltage, phase, and cycle and that all electrical wiring conforms to local codes and NEC regulations. If you are unsure of this voltage or are unfamiliar with electrical codes and regulations, have a professional electrician wire your pump for you or at least check your work. Failure to wire the pump correctly can cause electrical shock or can damage your pump motor and void your warranty.
1. Turn off the power to the Pro Logic at the main breaker.
2. Open the door to the Pro Logic box.
3. Remove the three blue screws that secure the cover plate.
4. Remove the cover plate.
5. A 2-speed pump requires using two relays inside the Pro Logic box. Steps 6-9 explain how to connect those relays to the breaker.
Note - The breaker needed is a 20 amp 2-pole circuit breaker. We used a Square D HOM series breaker. Check the Hayward Pro Logic manual for a full list of acceptable breakers.
6. Using black wire, connect one end to the bottom of the two-pole breaker and the opposite end to the first Line In spot on the Filter Pump relay.
7. Run a black jumper from the first line in spot on the Filter Pump relay to the first Line In spot on the Aux 2 relay. (You can use either of the Aux relays. We opted for the Aux 2)
8. Using red wire, connect one end to the top of the two pole breaker and the opposite end to second Line In spot on the Filter Pump relay.
9. Run a red jumper from the 2nd line in spot on the Filter Pump relay to the second Line In spot on the Aux 2 relay.
10. Steps 11-16 will cover connecting the 2-speed motor wires to the Pro Logic relay. A 2-speed motor requires four wires; two hot wires, one common wire, and the ground wire. We’ll use black, red, white and green wires respectively.
Note - We used 14 gauge wire for this installation. Your installation may require a different gauge.
11. Cut the wires to a length that will reach from the motor to the Pro Logic. Add an extra foot or two just to be safe.
12. The wire that we’ll use for high speed will be black. Connect the black wire to the second load out spot on the Filter Pump relay.
13. The wire that we’ll use for low speed will be red. Connect the red wire to the second load out spot on the Aux 2 relay.
14. The wire that we’ll use for the common line will be white. Connect the white wire to the first load out spot on the Aux 2 relay.
15. Run a white jumper from the first load out spot on the Aux 2 relay to the first load out spot on the Filter Pump relay.
16. The wire that we’ll use for the ground is green. Connect the green line to one of the grounding lugs on the grounding bar.
17. Feed all four wires, from step 12-16, through one of the knockouts and through the conduit back to the motor. At this point, you can reinstall the Pro Logic cover plate.
18. Loosen the two screws on the back cap of the motor and remove the cap.
19. Feed the wires through the conduit adapter at the motor.
20. The following steps explain how to connect the wires to the motor. In our example, we are using a Century SQS1102R. Note: Not all motors are the same. Make sure you look at the wiring diagram on your motor label.
21. Connect the black (high) line to the L1 terminal.
22. Connect the white (common) line to the L2 terminal.
23. Connect the red (low) line to the A terminal.
24. Connect the green (ground) line to the green screw.
25. Replace the black motor cap and tighten the screws.
26. Most pool pumps should be bonded. Connect the bonding wire to the bonding lug on the motor.
27. Congratulations! You have successfully wired the 2-speed motor to the Pro Logic.
