Product Overview<\/strong><\/h3>\n\n\n\n

The \u041f\u0440\u0438\u0432\u043e\u0434 \u0443\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u044f TEMP III<\/strong> is a high-performance, electronically controlled servo motor specifically designed to regulate the temperature blend damper<\/strong> in automotive Heating, Ventilation, and Air Conditioning (HVAC) systems. Widely used in Volkswagen (VW)<\/strong> vehicles and other European makes such as Audi, Seat, and Skoda, this actuator enables precise, continuous adjustment of cabin temperature by modulating the mix between hot and cold air streams.<\/p>\n\n\n\n

Unlike basic mechanical or on\/off actuators, the TEMP III features an advanced polarity-switching control mechanism<\/strong> combined with real-time position feedback<\/strong>, allowing the HVAC system to maintain consistent thermal comfort across varying environmental conditions. Its compact design, reliable operation, and OEM compatibility make it a critical component in modern vehicle climate control architectures.<\/p>\n\n\n\n

This actuator is especially valued in premium and mid-range vehicles where accurate temperature regulation<\/strong>, low noise operation<\/strong>, and long-term durability<\/strong> are essential for occupant comfort and system efficiency.<\/p>\n\n\n\n

Key Features & Technical Advantages<\/strong><\/h3>\n\n\n\n
    \n
  • Continuous Temperature Adjustment via Polarity Switching<\/strong>:
    The TEMP III actuator operates by reversing the polarity of the power supply wires (+\/-), which drives the motor to rotate the temperature damper smoothly through its full range. This allows for fine-tuned control over cabin warmth and cooling<\/strong>, enabling seamless transitions between different temperature settings without abrupt changes.<\/li>\n\n\n\n
  • Integrated Position Feedback System<\/strong>:
    Equipped with a potentiometer or Hall-effect sensor<\/strong>, the actuator provides real-time feedback on damper position to the HVAC ECU. This closed-loop control ensures accuracy, prevents over-travel, and enhances system stability\u2014critical for maintaining consistent climate performance.<\/li>\n\n\n\n
  • Adjustable Rotation Angle<\/strong>:
    Standard rotation angle is 90\u00b0 \u00b12\u00b0<\/strong>, but can be customized to meet specific OEM requirements. This flexibility supports integration into various HVAC housing designs and duct configurations.<\/li>\n\n\n\n
  • High Torque & Mechanical Strength<\/strong>:
    Delivers 3 kgf\u00b7cm running torque<\/strong> and up to 15 kgf\u00b7cm locked torque<\/strong>, ensuring robust operation even under mechanical resistance from dampers or internal friction. The high locked torque also helps maintain position during sudden vibrations or impacts.<\/li>\n\n\n\n
  • Low Power Consumption<\/strong>:
    Operates efficiently at just 3W<\/strong> with a maximum current draw of 100mA<\/strong>, minimizing load on the vehicle\u2019s electrical system and supporting energy efficiency goals.<\/li>\n\n\n\n
  • Quiet Operation<\/strong>:
    With a noise level of max. 43 dB(A)<\/strong>, it operates silently\u2014ideal for premium interiors where acoustic comfort is a priority.<\/li>\n\n\n\n
  • Wide Operating Temperature Range<\/strong>:
    Functions reliably in extreme environments from -30\u00b0C to +80\u00b0C<\/strong>, with storage capability up to +85\u00b0C<\/strong>, making it suitable for global markets and all seasonal conditions.<\/li>\n\n\n\n
  • Extended Service Life<\/strong>:
    Designed for up to 200,000 operational cycles<\/strong>, ensuring long-term reliability and reduced maintenance costs\u2014especially important in high-use vehicles.<\/li>\n\n\n\n
  • Compact & Lightweight Design<\/strong>:
    Measures 83.5 \u00d7 59 \u00d7 28 mm<\/strong> and weighs only 90g<\/strong>, allowing easy installation in tight HVAC compartments without compromising space or weight balance.<\/li>\n\n\n\n
  • Molded Electrical Connection<\/strong>:
    Features a molded wire harness connection<\/strong> for enhanced durability, moisture resistance, and secure electrical contact\u2014reducing the risk of corrosion or signal loss.<\/li>\n\n\n\n
  • OEM-Grade Quality & Certification<\/strong>:
    Complies with ISO 9001<\/strong> and TS16949<\/strong> standards, ensuring strict quality control, traceability, and compliance with international automotive manufacturing norms.<\/li>\n<\/ul>\n\n\n\n

    How It Works: Smart Climate Control Integration<\/strong><\/h3>\n\n\n\n

    The TEMP III Actuator operates using a DC motor-driven rotary mechanism<\/strong> connected to the temperature blend damper inside the HVAC unit. When the driver adjusts the temperature setting on the climate control panel, the HVAC ECU sends a control signal by reversing the polarity of the power supply:<\/p>\n\n\n\n

      \n
    • Positive Polarity (+)<\/strong> \u2192 Rotates the damper in one direction (e.g., toward hot air)<\/li>\n\n\n\n
    • Negative Polarity (-)<\/strong> \u2192 Rotates in the opposite direction (e.g., toward cold air)<\/li>\n<\/ul>\n\n\n\n

      As the damper moves, the internal position sensor continuously monitors its angle<\/strong> and sends feedback to the ECU. This enables the system to:<\/p>\n\n\n\n
