Abstract
A method for controlling a variable airflow apparatus to prevent processor overflow and underflow, with the variable airflow apparatus including an airflow sensor for providing an airflow sensor signal, a stored relationship between the airflow sensor signal and an airflow value, a damper for varying airflow, and an actuator for positioning the damper. The method includes energizing the airflow controller, determining either a minimum allowed airflow value based on the stored relationship between the airflow signal and an airflow value, or determining a maximum allowed airflow value based on the stored relationship, and periodically positioning the damper to provide an airflow value within a range limited by the minimum allowed airflow value or the maximum allowed airflow value in response to a signal from the airflow controller.
