OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TFACCY48TM480097

This is a genuine OEM Carrier Economizer Control Board Kit (part number HH63AW001), factory-specified for the Carrier TFACCY48TM480097 commercial packaged rooftop unit. The economizer control board is the command center of your unit's demand-controlled ventilation (DCV) and free-cooling system — it continuously monitors outdoor air conditions, CO₂ levels, and enthalpy inputs to determine when and how much outdoor air to introduce, reducing mechanical cooling loads and improving indoor air quality. When this board fails, symptoms include the economizer damper not responding, free-cooling mode not engaging, fault codes related to ventilation control, or the unit running at full mechanical cooling even in favorable outdoor conditions.
