This is the genuine OEM Carrier Economizer Control Board Kit (part number HH63AW001), the factory-specified replacement for the Carrier TFACCY50HJ484259 commercial rooftop unit. The economizer control module manages CO2-based demand-controlled ventilation, coordinates the rooftop economizer damper logic, and provides exhaust fan control output — all critical functions for maintaining indoor air quality and ASHRAE 62.1 compliance. When this board fails, you may experience fault codes related to economizer operation, loss of CO2 demand ventilation control, damper hunting or not responding, or complete economizer lockout on the rooftop unit.
Compatibility: Engineered for the Carrier TFACCY50HJ484259 commercial packaged rooftop unit. Mounts on the M7215 actuator or duct installation point. Verify your existing part number on the board label before ordering. Need help confirming fitment? Our parts specialists are available to verify compatibility before you order.
