Variable-speed replacement dedicated-purpose pool pump motor

means a replacement dedicated-purpose pool pump motor that is capable of operating at a variety of user-determined speeds, where all the speeds are separated by at most 100 revolutions per minute (RPM) increments over the operating range and the lowest operating speed is less than or equal to one-third of the maximum operating speed and is greater than zero. Such a motor must include a variable-speed drive and be sold or offered for sale either:

(A) with a user interface that changes the speed in response to preprogrammed user preferences and allows the user to select the duration of each speed, the operational times, or both; or

(B) without a user interface that changes the speed in response to preprogrammed user preferences and allows the user to select the duration of each speed, the operational times, or both, but is unable to operate without the presence of such a user interface.
