OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model PGACCY48HG480165

This is a genuine OEM Carrier Factory Authorized Part (part number HH63AW001), the factory-specified DCV Economizer Control Board Kit for the Carrier PGACCY48HG480165 packaged rooftop unit. The economizer control board serves as the decision-making center for the unit's economizer subsystem — it continuously monitors outdoor air conditions via connected sensors and modulates the damper actuator to optimize the blend of outdoor and return air. When this board fails, common symptoms include the economizer damper stuck fully open or closed, inability to meet setpoints, excessive energy consumption, loss of demand-controlled ventilation (DCV) functionality, or fault codes indicating economizer communication errors.
