Abstract
A motorized window covering has a motor and a housing that holds the motor and a dc battery. When the motor is energized to move a window covering, a pulse detector counts the electrical pulses of the motor to determine the position of the window covering. A user can save a current pulse count corresponding to a desired position and then return the desired position from a different position by simply pressing a button on a remote control unit.
