Abstract
A control for a hydromassage pump motor and pump controls the speed thereof at one of a plurality of predetermined speeds. The control includes a high voltage motor power control which is connected to the AC lines and to the motor to affect energization thereof and a low voltage user interface. The low voltage user interface is powered by a low cost, small, limited energy power supply which limits the current to the user interface and which provides electrical isolation from the AC lines.
