Abstract
A heating, ventilation, or air conditioning (HVAC) system with automated flow direction detection is provided. The HVAC system includes one or more hoses configured to provide airflow from HVAC equipment, a bidirectional pressure sensor coupled to the hoses, and a controller coupled to the bidirectional pressure sensor. The controller is configured to receive a signal from the bidirectional pressure sensor, determine a direction of the airflow relative to the bidirectional pressure sensor based on the signal, correct the signal for a reversed hose polarity relative to the bidirectional sensor based on the direction of the airflow, and perform a control activity using the corrected signal.
