Abstract
A method of operating a motorized window covering is presented wherein in response to a standard movement command power is supplied to a motor in a continuous or generally continuous manner thereby moving the shade material from a start position to an end position in a generally continuous manner. However, in doing so, the motor rotates at a fast rate thereby causing elevated noise levels. In response to an automated movement command, power is supplied to the motor by cycling power to the motor between a powered state and an unpowered state thereby moving the shade material from a start position to an end position in an incremental manner. While moving the shade material in this incremental manner is slower, it is substantially quieter. The preferred mode of operation is selected based on whether the movement command is a standard movement command or an automated movement command.
