OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TCACCY50TM480019

This is a genuine OEM Carrier Economizer Control Board Kit (part# HH63AW001), the factory-specified replacement for the Carrier TCACCY50TM480019 commercial rooftop unit. The economizer control board acts as the decision-making hub for your unit's economizer system — continuously reading outdoor air enthalpy and CO₂/DCV sensor inputs to modulate the outdoor air damper and maximize free cooling while minimizing mechanical refrigeration run time. When this board fails, symptoms include economizer dampers stuck open or closed, loss of demand-controlled ventilation (DCV) function, fault codes related to economizer operation, or a noticeable spike in energy costs due to uncontrolled outside air intake.

  • Specs: 120V | 60Hz | DCV (Demand-Controlled Ventilation) capable | Dimensions approx. 4" × 4" × 2" | Weight: 1 lb | Cross-reference: W7212A1017
  • OEM vs Generic: This factory-authorized OEM board is pre-programmed and calibrated to Carrier RTU specifications. Generic or aftermarket economizer boards often require additional configuration and may lack full DCV compatibility, risking improper ventilation control and potential code violations.
  • Install difficulty: 3/5 — Disconnect power at the disconnect box before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, smartphone/camera for wiring documentation. Label and photograph all harness connectors before removal. Commercial rooftop work should be performed by a licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier TCACCY50TM480019 commercial packaged rooftop unit. Cross-references Honeywell W7212A1017. Always verify your existing board's part number and input/output configuration against your unit's wiring diagram before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCACCY50TM480019?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCACCY50TM480019. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCACCY50TM480019?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
