FAW Logic Assembly For Air Conditioning Equipment Installation: 19 Critical Components for Flawless Climate Control

Welcome to this definitive guide to the FAW Logic Assembly For Air Conditioning Equipment Installation (Assembly 710). This is the complete, 19-component-type, “dual-zone automatic” climate control system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 diesel semi-trailer tractor. This is the “brain” and “lungs” of the cab’s comfort system, a “logic” assembly that goes beyond simple heating and cooling.

The “automatic” logic of this FAW Logic Assembly For Air Conditioning Equipment Installation means it is a “smart” system. It uses an ‘Automatic A/C operating mechanism’ (8112010AD04-C00) to interpret driver commands and sensor data (like the ‘In-cab temp sensor’ from Assembly 709). Its “dual-zone” logic, managed by the ‘Dual-zone box assy’ (8100015AD04-C00), allows it to blend hot and cold air to maintain a perfect, pre-set temperature.

This in-depth guide is an essential resource for HVAC technicians and parts managers. We will deconstruct the entire FAW Logic Assembly For Air Conditioning Equipment Installation into its 19 serviceable component types. We will analyze the “core” logic of the ‘Dual-zone box’, the “air-handling” logic of the ducts and filter, the “drainage” logic of the hose system, and the critical “anti-vibration” fastener system.

Core 1: The “Dual-Zone” & Operating Logic (Components 1 & 19) (The “Longer” Module)

This group represents the “brain” and “heart” of the FAW Logic Assembly For Air Conditioning Equipment Installation. These two components are the core “black boxes” that manage the entire system.

1. Component 1: ‘Dual-zone box assy – automatic A/C’ (8100015AD04-C00)

This is the primary serviceable component. It is the main “plenum” or “air-box” that is mounted deep inside the ‘Dashboard’ (Assembly 647). Its “logic” is to be the “meeting point” for all air.

“Blending Logic”: Inside this box, the “cold” air from the ‘Evaporator’ (709) and the “hot” air from the ‘Heater Core’ (709) are mixed. This box contains the “blend doors”—small flaps operated by ‘Servo Motors’ (709, P/N 8101051-A65-C00). The “automatic” logic is that the ‘Operating Mechanism’ (Component 19) tells these doors *how much* to open or close, precisely blending the air to achieve the driver’s set temperature (e.g., 22°C).

“Dual-Zone Logic”: This box is a “dual-zone” unit. This “logic” means it has *separate* blend doors for the driver’s side and the passenger’s side. This allows the driver to have their heat on while the passenger (or sleeper) has the A/C on, a critical “comfort logic” for long-haul team driving.

2. Component 19: ‘Automatic A/C operating mechanism assy’ (8112010AD04-C00)

This is the “brain” of the FAW Logic Assembly For Air Conditioning Equipment Installation. It is the “climate control head unit” that the driver interacts with.

“Control Logic”: This component’s “logic” is to be the central computer. It takes “inputs” from the driver (e.g., “set temp to 22°C”) and “inputs” from the sensors (e.g., the ‘In-cab temp sensor’ (709) reads 20°C). It then “logically” decides what to do. It calculates that it needs to *add heat* and sends an “output” signal to the ‘Central Drive’ (709) to move the “blend door” slightly towards “hot.”

This serviceable part also includes the ‘Independent Cold Air’ (独立冷风) function, a “logic” that allows the driver to run the A/C *without* the engine running (via the independent heater’s power source), which is essential for “no-idle” sleeper comfort.

Core 2: The “Air Handling & Filtration” Logic (Components 3, 6, 7)

This group of components manages the *path* of the air for the FAW Logic Assembly For Air Conditioning Equipment Installation.

Component 3: ‘Outside air filter’ (8101570-D04): This is the “lung protection” logic. This is the “cabin air filter.” It is a serviceable part (MSU) that is “upstream” of the entire system. Its “logic” is to filter all *outside* air *before* it enters the ‘Blower’ (709). It traps dust, pollen, and road grime, protecting both the driver’s lungs and the ‘Evaporator’ (709) core from getting clogged.

Components 6 & 7: ‘Blower duct assy’ (8101160-A01 / 8101185-B27-C00): These are the “arteries” of the system. Their “logic” is to be the “plumbing” that delivers the conditioned air from the ‘Dual-zone box’ (Component 1) to the driver. The ‘Blower duct’ (6) is for the main “footwell” (脚风道) heat, while the ‘Passenger footwell duct’ (7) is a specific branch for the passenger.

Core 3: The “Water Drainage” Logic (Components 9, 10, 13)

This is one of the most critical, and most common, failure points of any A/C system. The “logic” of the ‘Evaporator’ (709) is that it *pulls moisture* (humidity) from the air. This water must go somewhere.

Component 9: ‘Drain hose’ (8107066-A01): This is the “drain pipe.” Its “logic” is to collect the condensation from the ‘Dual-zone box’ (Component 1) and safely route it *outside* the cab, where it drips on the ground.

Component 10: ‘Drain hose sleeve’ (8107047-A01): This is the “anti-chafe” logic. It is a protective “sleeve” that guards the hose (Component 9) as it passes through the metal ‘Firewall’ (617).

Component 13: ‘Drain hose fixed bracket’ (8100106-A01): This is the “anti-kink” logic. This bracket holds the hose at a specific *downward angle*.

Failure Logic: If this “drainage logic” fails (the hose is clogged by a spider web, or “kinked” by a missing bracket), the water *backs up*. It floods the ‘Dual-zone box’, leaks out, and *saturates* the ‘Floor Carpet’ (692) and ‘Soundproofing Pad’ (623). This is a catastrophic failure that leads to mold, mildew, and total rust-out of the cab floor. This makes these simple, cheap components critical serviceable parts.

Core 4: The “Fastener & Info” Logic (Components 2, 4, 5, 8, 11, 12, 14, 15, 18)

This final group is the “installation” and “information” logic for the FAW Logic Assembly For Air Conditioning Equipment Installation.

Fastener “Logic”: The system uses a 14-piece “anti-vibration” fastener kit.

• Bolts/Nuts (2, 5, 11, 12, 14): This combination of ‘Hexagon bolts’, ‘Hexagon nuts’, ‘Flange nuts’, and ‘Combination bolts’ is the “structural logic.” They are used to mount the heavy ‘Dual-zone box’ (Component 1) and ‘Drain hose bracket’ (Component 13) to the cab’s structural frame.
• ‘Self-tapping screw’ (8, 18): This is the “polymer-safe” logic. These 6 screws (with their washers) are used to fasten the *plastic* ‘Blower ducts’ (6 & 7) to the *plastic* ‘Dual-zone box’, ensuring a tight, rattle-free, plastic-on-plastic connection.

Information “Logic” (16, 17): These are the ‘A/C maintenance notice’ and ‘Independent cold air… manual’. This is the “human logic” component, providing the driver and technician with critical instructions (in Chinese) for operation and service.
