Dongfeng KL truck parts Automatic air conditioning controller assembly 8112010-C3103

At the core of this assembly is its advanced automatic climate control function, powered by a high-precision microprocessor and dual NTC temperature sensors (cab interior and ambient). Drivers simply set a target temperature (16–30°C, 0.5°C increments), and the controller automatically adjusts AC compressor output, blower speed (6 levels), air mode (face/feet/defrost/dual-zone), and recirculation status to maintain the set temperature within ±0.3°C. For example, in hot weather, it activates maximum cooling until the target is reached, then switches to low-power maintenance mode; in cold conditions, it coordinates with the heater core to deliver warm air without temperature fluctuations. Unlike manual controllers that require constant adjustments, this intelligent system reduces driver distraction, improves energy efficiency (cutting AC-related fuel consumption by 12%), and ensures consistent cab comfort in all climates

Designed to meet diverse comfort needs, the controller integrates comprehensive functions and supports optional dual-zone control (for cabs with separate driver/passenger AC vents). Key features include: one-touch defog (activates max blower + defrost mode to clear windshield fog in 60 seconds), rear defogger activation (with 15-minute auto-shutoff to prevent battery drain), air purification mode (triggers cabin air filter circulation), and memory function (restores last used settings after truck restart). The interface uses a combination of tactile rotating knobs (for temperature/speed) and backlit touch buttons (for mode selection)—both with clear, wear-resistant labels (UV-printed to avoid fading). The 2.4-inch LCD display shows real-time temperature, mode, and filter status with high contrast, ensuring readability in direct sunlight or night driving. This multi-functional design caters to both driver and passenger comfort, making it ideal for long-haul teams

Built to withstand the rigors of commercial truck use—including constant vibration, temperature extremes, and dust—the assembly uses rugged materials and reinforced design. The front panel is made of impact-resistant PC/ABS plastic (UL94 V-0 flame-retardant rating) with a scratch-resistant coating, enduring 10,000+ wipe cycles (with cleaning cloths) without visible damage. Internal components: the circuit board is coated with a 0.2mm conformal epoxy layer (resisting moisture, dust, and electrical interference), and the connector pins are gold-plated (ensuring low-resistance contact for 300,000+ insertion/removal cycles). Rubber dampers on the mounting bracket absorb 70% of road vibration (10–2,000 Hz frequency range), preventing internal part loosening or solder joint failure. Unlike consumer-grade AC controllers that fail in 1–2 years, this assembly operates reliably in temperatures from -40°C to 90°C for 5+ years

Engineered for hassle-free troubleshooting and maintenance, the controller includes a built-in self-diagnostic system. If the AC system malfunctions (e.g., compressor failure, sensor error, or blower motor issue), it detects the fault via CAN bus communication with the truck’s ECU and displays a specific error code (e.g., “E03” for ambient sensor fault) on the LCD screen. Technicians can use the code to quickly identify issues, reducing diagnostic time by 50% compared to controllers without this feature. The controller also alerts drivers to cabin air filter replacement (via a “FILTER” indicator) after 15,000 km of use, ensuring optimal air quality. Installation requires only basic tools (socket wrench, trim panel tool) and takes 30–45 minutes, as it aligns with factory mounting points. Backed by a 24-month warranty against manufacturing defects (e.g., display failure, button malfunction, or circuit board damage), it provides Dongfeng KL truck owners with a reliable, low-maintenance automatic climate control solution
