OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TFACCY48TM480093

This is a genuine OEM Carrier Economizer Control Board Kit (part number HH63AW001), factory-specified for the Carrier TFACCY48TM480093 packaged rooftop unit. The economizer control board is the intelligence center of your unit's demand-controlled ventilation (DCV) system — it continuously monitors outdoor air conditions, interprets CO₂ or enthalpy sensor signals, and modulates the economizer damper to optimize fresh air intake while minimizing energy consumption. When this board fails, you'll typically see fault codes related to economizer operation, a damper stuck open or closed, loss of IAQ control, or the unit defaulting to minimum ventilation regardless of occupancy load.
