Thread: Hayward/AO Smith motor/intermatic timer question

    Hayward/AO Smith motor/intermatic timer question

    I removed my single speed motor with a Hayward/AO Smith TriStar two speed motor. The single speed motor was controlled (on and off) by a T104M intermatic timer. Now, when I turn the breaker on, the motor runs at low speed, with the timer in the off position. When I turn on the timer, the motor switches to high speed. I was told that I needed to add a second timer, a intermatic T106M to the system. Has anyone had this issue? What is the wiring diagram if using the two switches.
    Any help would be appreciated.

    The T104 is a double pole but only a single throw. So it won't operate a 2-speed pump properly.

    If your existing enclosure has enough room to add the T106M then that's probably the easiest way to go but if it's a single box then you might be better off getting the T10604R which is a double enclosure with the timers in it.

    Thank you very much. I do have the room for the T106M. Do you have any wiring instructions for me to follow to wire up the two timers?
