OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TFACCY48TM480096

This is a genuine OEM Carrier Factory Authorized Part — the HH63AW001 DCV Economizer Control Board Kit — engineered as the factory-specified replacement for the Carrier TFACCY48TM480096 commercial packaged unit. The economizer control board is the electronic brain of your unit's free-cooling and demand-controlled ventilation (DCV) system. It continuously monitors outdoor air conditions, CO₂ sensor inputs, and enthalpy levels to regulate the economizer damper, maximizing energy recovery and maintaining required fresh-air ventilation rates. When this board fails, you may experience economizer faults locked on the thermostat or building automation system, dampers stuck fully open or fully closed, DCV sensor communication errors, or the unit running mechanical cooling during favorable outdoor conditions — all of which drive up energy costs and compromise occupant comfort and indoor air quality.

• Specs: OEM Part# HH63AW001 | Cross-reference: W7212A1017 | Input voltage: 120V / 60Hz | Dimensions: 4" × 4" × 2" | Weight: 1 lb | Factory Authorized Parts — Carrier Corporation
• OEM vs Generic: This board ships as a complete OEM kit with factory-matched firmware, pre-calibrated DCV thresholds, and all mounting hardware included. Aftermarket boards often lack DCV logic compatibility, risking ventilation code violations and compressor short-cycling.
• Install Difficulty: 4/5 — Commercial-grade board replacement. Requires de-energizing the unit at the disconnect, photographing all wiring harness connections before removal, and verifying CO₂ sensor and enthalpy sensor wiring terminations post-install. Tools needed: insulated screwdrivers, needle-nose pliers, multimeter, and laptop with BAS access if fault codes need clearing. Recommend a licensed commercial HVAC technician.
• Warranty: 1-year OEM manufacturer warranty on parts. Ships same business day from our warehouse. Carefully inspect all wiring and harness connectors before installation — electrical parts are non-returnable once installed.

Compatibility: Designed for the Carrier TFACCY48TM480096 commercial packaged rooftop unit. Cross-references with Honeywell W7212A1017.
