2.17.2. System of heating and ventilation of salon (without air conditioning)

Fig. 2.29. Elements of the control panel of heating and ventilation of salon: 1 — the regulator of speed control of the fan; 2 — the selector switch of the modes; 3 — the regulator of temperature of the given air; 4 — the switch of an electrical heating of back glass and external rear-view mirrors; 5 — the air recirculation mode switch

The system of heating and ventilation has the corresponding control panel (fig. 2.29).

Description of purpose of various elements of the control panel of heating and ventilation of salon:

1) the regulator of speed control of the fan has 6 provisions corresponding to various speeds of its work (respectively: 0 — выкл, 6 — the highest speed of operation of the fan);

2) selector switch of the modes of various directions of intake of air. The switch can be installed in any intermediate position between the designated modes. The possible directions of streams of air, and also the relevant provisions of this selector switch are presented in fig. 2.30,2.31,2.32,2.33,2.34.

Remember that at open air vents on the dashboard through them always there passes an air quantity, irrespective of position of the selector switch of the mode. For receiving the maximum air stream to a floor or on windows it is necessary to close these air vents. For prevention of repeated fogging of side glasses open two extreme air vents;

3) the regulator of temperature of the given air allows to carry out step regulation from the cold arriving air (extreme left situation) to warm (extreme right situation);

4) heater of back glass, heaters of external rear-view mirrors.

At the switched-off mode of heating the LED indicator lights up;

5) air recirculation mode switch. At the included situation fresh air does not move in interior of the car that is necessary for prevention of penetration of exhaust gases of surrounding cars. When using this operating mode the LED indicator lights up. During the work in the mode of recirculation it is recommended to use the timer. It is necessary to regulate temperature of the arriving air the selector switch of temperature. When using of this mode in cold or damp weather fogging of windows is possible.

Function of the timer during the work in the mode of recirculation minimizes risk of frosting, fogging and closeness in salon. Execute the following operation: press the switch of the mode of recirculation of air and hold its pressed more than 3 pages. During 5 with the light-emitting diode will blink. Recirculation of air in the car will be included approximately

5 minutes. By each pressing of the switch the timer will become more active. If it is required to turn off function of the timer, again press the switch and hold its pressed more than 3 pages. For confirmation of the made choice during 5 with the light-emitting diode will burn.
