OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TFACCYCRECOMZR020A02

This is a genuine OEM Carrier Factory Authorized Parts replacement for the Carrier TFACCYCRECOMZR020A02 economizer assembly. The DCV (Demand-Controlled Ventilation) economizer control board serves as the intelligence center of the economizer module — continuously monitoring outdoor air enthalpy or dry-bulb conditions, staging damper actuators, and coordinating CO₂ or occupancy sensor inputs to maximize free cooling while minimizing mechanical cooling energy costs. When this board fails, you may experience a stuck-open or stuck-closed damper, loss of free-cooling mode, fault codes on your BAS or RTU controller, or complete economizer lockout.

• Specs: OEM Part# HH63AW001 | Cross-reference: W7212A1017 | Input voltage: 120V / 60Hz | All inputs Class 2 | Dimensions approx. 4" × 4" × 2" | Weight: 1 lb | Factory Authorized Parts — Carrier Corporation
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact factory tolerances. Generic economizer boards often lack proper sensor calibration curves and enthalpy algorithm tuning, leading to improper damper staging, energy waste, and premature actuator wear. OEM is always the recommended choice for commercial RTU economizer applications.
• Install difficulty: 3/5 — Economizer board replacement requires familiarity with commercial rooftop unit wiring and Class 2 low-voltage circuits. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and wiring diagram (available in unit service manual). Always de-energize the unit at the disconnect before servicing. Photograph all wiring connections before removal. Sensor wiring polarity must be observed during reinstallation.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse — get your economizer back online fast.
