The Lennox 17A08 BACnet control kit (A0CTRL31LS1) is a genuine OEM communication and control module that connects your Lennox rooftop or packaged unit to a building automation system (BAS) over the BACnet protocol. It allows a central control system to monitor and command heating, cooling, fan, and economizer operation, delivering coordinated setpoint control, scheduling, and fault reporting across your equipment.

Common failure symptoms: A failing or missing control kit can cause loss of BAS communication, unresponsive setpoints, unit lockouts, missing status or alarm data at the front end, erratic staging, or an inability to remotely command heat, cool, or ventilation. Power surges, moisture, and aging electronics are common culprits.

Why OEM matters: BACnet integration depends on firmware, object mapping, and hardware that exactly match your Lennox controller. The OEM 17A08 kit is validated for seamless communication with Lennox unit controls — generic substitutes risk incompatible objects, dropped points, and integration failures. Install the factory-spec part for dependable building automation performance. In stock and ready to ship same day.

Frequently Asked Questions

Does this Control Board fit my Lennox OEM Lennox BACnet Control Kit — 17A08?
Yes. This is the factory-specified OEM control board for the Lennox OEM Lennox BACnet Control Kit — 17A08. 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 Lennox OEM Lennox BACnet Control Kit — 17A08?
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 Lennox 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 Lennox 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.
