This guide will explain how 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.
Open the door to the Pro Logic box.
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.
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. Check out our recommended wire size chart for gauge requirements.
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.
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.
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.
Congratulations! You have successfully wired the 2-speed motor to the Pro Logic.
