6  Classification of pump-units – meaning of single, two, multi and variable speed
  In this Determination:
  a pump-unit is single speed if it has a single discrete nominal motor speed that is fixed by the manufacturer.

                  a pump-unit is two speed if it has two discrete nominal motor speeds that are fixed by the manufacturer. The speed settings may be selectable by the user or installer or control system, but the user or installer or control system cannot change the speed assigned by the manufacturer to each discrete speed setting.

         a pump-unit is multi speed if it has three or more discrete nominal motor speeds that are fixed by the manufacturer. The speed settings may be selectable by the user or installer or control system, but the user or installer or control system cannot change the speed assigned to each discrete speed setting.

         a pump-unit is variable speed if it has continuously variable speeds, where the speed may be set or reset by the user or installer or control system.
