Abstract: A motor calibration system and method for a motor having a rotor and a stator and comprising at least one phase. The system further comprises at least one position detector adapted to detect a position of the rotor with respect to the stator and generate a feedback signal and a controller adapted to perform a calibration sequence to calibrate to motor. Wherein the controller calibrates the motor by driving at least one motor phase with a motor control signal at a predetermined maximum amplitude value in a first direction with substantially no load applied on the motor, receiving a feedback signal from the at least one position detector, and determining a first calibration angle shift by measuring a difference between at least the motor control signal and the feedback signal of the at least one motor phase. The controller accounts for the first calibration angle shift when driving the motor in the first direction during normal operation. According to one embodiment, the controller may determine a second calibration angle shift for a second direction in a similar manner. According to another embodiment, the may determine the second calibration angle shift using a transformation function and a predetermined angle shift sum constant.

Abstract: A motorized window treatment configure for automatically determining and reporting the tilt level of a motorized window treatment. The motorized window treatment comprises a window covering material, a motor configured for moving the window covering material from an opened position to a closed position, an accelerometer configured for measuring gravitational forces, and a controller configured for reporting the tilt level of the motorized window treatment. Particularly, the controller receives gravitational force measurements from the accelerometer, determines a tilt level of the motorized window treatment using the gravitational force measurements, compares the tilt level to a first threshold value, and issues an error signal when the tilt level exceeds the first threshold value.

Abstract: Systems, methods, and modes for commissioning of a building control system comprising at least one controller and a plurality of control devices comprising a plurality of multicolored LEDs and at least one button for controlling at least one associated electrical load. Each control device is assigned a different color sequence comprising a plurality of colors and commanded to drive the plurality of LEDs to illuminate according to the assigned color sequence. The at least one controller receives a logical object and an identification of a plurality of illuminated colors of a control device to be commissioned, selects a control device from the plurality of control devices commanded to illuminate a color sequence that matches the received identification of the plurality of illuminated colors, and associates the selected control device with the received logical object.

Abstract: A roller shade comprising a motor pretensioned counterbalancing spring that lowers the torque load on the motor of the roller shade throughout the rolling up or rolling down cycles. The roller shade comprises a motor drive unit including a motor adapted to drive a drive wheel through a clutch. The motor drive unit further comprises a first spring carrier adapted to be stationary during operation of the motor and a second spring carrier adapted to rotate during operation of the motor. The motor drive unit further comprises a counterbalancing spring connected at its first end to the first spring carrier and at its second end to the second spring carrier. The counterbalancing spring is pretensioned using the motor prior to inserting the motor drive unit into the roller tube by driving the drive wheel and thereby rotating the second end of the counterbalancing spring with respect to the first end of the counterbalancing spring. The clutch translates rotational motion from the motor to the drive wheel, but locks rotational motion from the drive wheel thereby locking the pretension in the counterbalancing spring.
