The DCV (Demand Controlled Ventilation) economizer control board serves as the intelligence center of the unit's economizer assembly — continuously monitoring outdoor air conditions, CO₂ levels, and enthalpy to optimize the blend of outside and return air. When this board fails, common symptoms include the economizer damper stuck open or closed, loss of demand-controlled ventilation, fault codes related to the economizer circuit, degraded indoor air quality, and increased energy consumption as the system can no longer take advantage of free-cooling conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e HH63AW001 | Cross-reference: W7212A1017 | Factory Authorized Carrier replacement part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V | 60Hz | DCV (Demand Controlled Ventilation) compatible | Dimensions approx. 4\" × 4\" × 2\" | Weight: 1 lb | All inputs Class 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized board engineered to exact tolerances for the TFACCY50HJ484260.
