OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TFACCY48TM480100

This is the genuine OEM factory-replacement Economizer Control Board Kit (HH63AW001) for the Carrier TFACCY48TM480100 commercial packaged rooftop unit. The economizer control board is the brain of the economizer subsystem — it continuously monitors outdoor air conditions, interprets demand-controlled ventilation (DCV) signals, and commands the damper actuator to bring in the precise amount of fresh outside air needed to satisfy both indoor air quality (IAQ) and energy efficiency requirements. When this board fails, symptoms typically include a stuck-open or stuck-closed damper, loss of DCV response, fault codes on the unit controller, or complete economizer lockout — all of which can trigger building code compliance issues and spike energy costs on commercial rooftop installations.

• OEM Part Number: HH63AW001 | Cross-Reference: W7212A1017 | Factory Authorized Carrier Replacement Components Division part
• Specs: 120V input | 60 Hz | All inputs Class 2 rated | Dimensions approx. 4" × 4" × 2" | Weight: 1 lb | Designed for DCV (Demand-Controlled Ventilation) economizer systems on Carrier commercial RTU platforms
• OEM vs Generic: OEM boards are programmed with Carrier-specific firmware and factory-calibrated sensor thresholds. Third-party substitutes frequently lack DCV compatibility, cause damper hunting, or trigger false fault codes — leaving your rooftop unit non-compliant and your warranty void.
• Install Difficulty: 3/5 — This is a commercial rooftop board replacement. Tools required: insulated screwdrivers, multimeter, low-voltage wire labels, and access to unit wiring diagram. De-energize the unit fully before opening the economizer compartment. Document all wiring connections with photographs before disconnecting. Allow 10–15 minutes for the new board to initialize on first power-up.
• Warranty: 1-year OEM factory warranty through Carrier. Ships same business day from our warehouse in original Carrier Factory Authorized Parts packaging.
