ABSTRACT:
A skylight operator includes a chain drive driven by a motor. Polarity of power applied to the motor is controlled to selectively open or close the window. Polarity is controlled by an H-bridge switching circuit driven by a microcontroller. The microcontroller receives commands from any one of a plurality of control devices The operator includes a feedback circuit using a hall effect sensor in connection with a ring magnet on the motor shaft for sensing incremental movement of the motor, representing movement of the window. A potentiometer control device allows unattended full or partial opening of the window. A user need only turn the potentiometer knob to a desired amount of opening. The microcontroller in response to such a command compares the command to the feedback signal and controls the motor to minimize the difference between the two.
