    Question Timer for two speed B2982

    Got a sweet, sweet deal on a Century B2982 motor, with no timer. At $175, I could not pass up the opportunity. This leaves me with the question of how to control this two speed motor.

    My current timer is a Tork P1104-M mechanical timer inside a Tork PP-125-R-P4 panel. Perfect for single speed motors, but does not seem to support my two speed needs.

    I would consider the 2Green timer normally included with the B2982T product, but I can't find it as a separate item nor can I find a part number for the bare timer.

    For whatever solution, I prefer to avoid having a single hot leg live to the motor.

    I'm looking for thoughts and suggestions, please.

    Thank you.

    The T106 switches from high to low so you would keep your existing timer for on/off and add the T106 to switch high/low.

    If you dont need a timer for high/low, you can do it manually by using a two speed switch.

    Also note that the new motor is 1.65 total hp. You list the current motor as 2 hp. You need to make sure that your impeller is correct for 1.65 total hp.

    If your current impeller is for more than 1.65 total hp, you will need to replace the impeller.

    I was going to start a new thread to discuss the impeller change, but you beat me to it.

    Current pump is Challenger 2hp CFII-N1-2A, with an AO Smith rated SF 1.1. From the information on this website, I believe this is an uprated 1.5hp motor. Thus, for the new motor I need the impeller for a 1 HP full rated motor, which I believe is Pentair part number 35-5074.
