We claim: 1. An adjustable covering for an architectural opening in combination with a control system, a motor, and a remote control having an up button and a down button, said control system being configured to execute at least one computer readable instruction for controlling the operation of the adjustable covering, wherein the covering includes a pair of flexible elements and a plurality of parallel vanes interconnecting the flexible elements, said covering being movable between retracted and extended positions and said vanes being pivotable between open and closed positions, said vanes remaining in said closed position when said covering is moving between said extended and retracted positions and being movable between said open and closed positions only when said covering is fully extended, said control system executing said instruction by: receiving a first signal from said remote control wherein the first signal is generated upon a single press and release of the down button; outputting a second signal upon receiving said first signal, which activates said motor to begin extending the adjustable covering; outputting a third signal which deactivates the motor after the adjustable covering reaches full extension and while the adjustable vanes are in a closed position; receiving the first signal from the remote control for a second time after outputting the third signal, wherein the first signal is again generated upon a single press and release of the down button; and outputting the second signal activating the motor to begin rotating the roll bar to move the vanes from the closed toward an open position while the covering is fully extended. 2. The combination of claim 1 wherein said control system again after outputting said second signal for the second time receives at least one of a fourth signal or a first signal indicating a single press and release, respectively, of one of the up button and the down button, and outputs a third signal to deactivate the motor before the vanes are fully open. 3. The combination of claim 1 wherein said control system during extension of the adjustable covering, receives at least one of a fourth signal or the first signal indicating a single press and release, respectively, of one of the up button and the down button, and outputting a third signal to deactivate the motor. 4. An adjustable covering for an architectural opening in combination with a control system, a motor, and a remote control having an up button and a down button, said control system being configured to execute at least one computer readable instruction for controlling the operation of the adjustable covering, wherein the covering includes a bottom rail, a pair of flexible elements and a plurality of parallel vanes interconnecting the flexible elements, said covering being movable between retracted and extended positions and said vanes being pivotable between open and closed positions, said vanes remaining in said closed position when said covering is moving between said extended and retracted positions and being movable between said open and closed positions only when said covering is fully extended, said control system including a processor adapted to execute at least one computer readable instruction to adjust the position of the covering by: detecting a signal indicative of a desired adjustment of the covering; activating said motor when the vanes are in a closed position and the window covering is at least partially retracted to move the covering toward the extended position; while the motor is activated, detecting a signal indicative of a second desired adjustment of the covering when the covering is fully extended but the vanes remain closed; deactivating the motor upon detection of the signal indicative of the second desired adjustment; detecting a signal from the remote control generated upon a single press and release of the down button indicative of a third desired adjustment of the covering; upon detection of the signal indicative of the third desired adjustment of the covering, activating the motor until the vanes move from a closed to an open position; sensing when the vanes in the covering have been moved to the fully open position; and deactivating the motor when the vanes reach the fully open position. 5. The combination of claim 4 wherein: the detection of the signal indicative of a second desired adjustment is in response to detecting contact between said bottom rail of the window covering and a window frame in which the covering is mounted.
