Abstract
Methods and apparatus to operate a covering of an architectural covering are disclosed. An example apparatus includes a clutch to disengage a motor when the motor is not in use. The dual control architectural covering further includes a clutch to disengage a motor from moving a covering to facilitate manual operation of the covering of an architectural covering when the motor is not in use; and a controller: to track a covering position based on a first encoder measurement from a first encoder; and to track a motor position when the motor disengages based on a second encoder measurement from a second encoder different from the first encoder.
