This is a genuine OEM Carrier Factory Authorized Part — the HH63AW001 DCV Economizer Control Board Kit — factory-specified for the Carrier TCHC1850HE401482 commercial rooftop unit. The economizer control board is the intelligence center of your unit's free-cooling system: it continuously monitors outdoor air conditions via CO₂ and/or enthalpy sensors, modulates the economizer damper position, and coordinates with the main unit controls to maximize energy efficiency while maintaining ASHRAE 62.1-compliant ventilation. When this board fails, symptoms include stuck-open or stuck-closed dampers, ventilation fault codes, erratic damper hunting, failure to enter free-cooling mode, or a complete loss of economizer function — all of which can trigger building code non-compliance flags and spike energy costs.
Compatibility: Direct OEM replacement for Carrier model TCHC1850HE401482 commercial rooftop units equipped with the factory DCV economizer option. Also cross-references W7212A1017. Confirm your existing board's part number on the label before ordering — our team is available to verify fitment. Order today for same-day dispatch.
