Elements of automatic heating systems (HAU)

Passenger compartment temperature sensor installed in the front room lamp. For a quick fix temperature fluctuations inside the indoor air is constantly pumped through the sensor - it is on it with a small fan. The temperature in the interior regardless of the vehicle speed is constantly maintained at a predetermined value.

Temperature sensors are installed on the body of the radiator heater under the dashboard for each of the two radiators. They determine the temperature directly behind radiators and transmit information to automatically adjust the unit. In the latter processes signals from the temperature sensor in the cabin and from each of the sensors on the radiator at a predetermined ratio. So determined by the actual value of the temperature in the cabin. To make a particular adjustment of the actual value is compared with the set. To enhance the heat is the heater fan. Fan speed is regulated by an electronic control unit.

Cleaning filter air entering the cabin, from the dust. With the help of filtered fresh air and recirculated air. Replacement filter element is located directly in front of the fan. Depending on the magnitude of the dust particle filtration rate can reach 100%. Filter consisting of a polycarbonate, and carries an electrostatic filter. It is insensitive to water and has a low air resistance. Cleaning the filter is not possible.

Exhaust air from the passenger compartment through the opening for the rear shelf extends between the body and the plastic upholstery of the right rear trunk trim. Through the ventilation flap at the right side part of the shock absorber it is printed out.
