Cabin temperature sensor installed in the front dome light. To quickly capture temperature fluctuations in the cabin, internal air is constantly pumped through the sensor - for this, a small fan is installed on it. The temperature in the passenger compartment, regardless of the speed of the vehicle, is constantly maintained at the level of the set value.
Radiator temperature sensors installed on the heater housing under the instrument panel behind each of the two radiators. They determine the temperature directly behind the radiators and transmit information to the automatic control unit. In the latter, the signals from the temperature sensor in the cabin and from each of the sensors on the radiators with a given ratio are processed. This determines the actual temperature in the passenger compartment. To perform a particular adjustment, the actual value is compared with the set value. The heater fan is used to enhance the heating. The fan speed is controlled by the electronic control unit.
Cleaning filter air entering the cabin from dust. It filters the supply and recirculated air. The replaceable filter element is located directly in front of the fan. Depending on the size of the dust particles, the degree of filtration can reach 100%. The polycarbonate filter also performs electrostatic filtration. It is insensitive to water and has low air resistance. The filter cannot be cleaned.
exhaust air from the passenger compartment through the hole behind the rear shelf passes between the body and the plastic upholstery behind the right rear trunk upholstery. Through the ventilation flap under the right side of the shock absorber strut, it is brought out.
