Fig. 1.33. Control panel heating and ventilation system

The temperature and the direction of supply of air in salon is regulated by handles on the control panel heating and ventilation system (fig. 1.33) .

Fig. 1.34. Control panel system of heating and Termotronic ventilation

In addition to system of heating and ventilation the device of automatic control of air temperature in Termotronic salon (fig. 1.34) can be established . She establishes the set temperature in salon of the car quicker and automatically supports its constant value.

Switches of systems of heating and ventilation or conditioning are shown on fig. 1.33 – 1.35 ).

I\switch of operating modes of the fan of the supercharger of air.

Positions of the switch:

0–the fan is switched off;

1–low frequency of rotation of the fan;

2–average frequency of rotation of the fan;

3–high frequency of rotation of the fan.

In position of the switch I between 0 and 1 supply of air in salon of the car it is regulated without the fan.

II\switch of a regulator of air temperature. At switch turn to the left in salon cold air, to the right — hot moves. For Termotronic system digital designations on the control panel correspond to the temperature supported in salon.

Fig. 1.36. System of supply of air in salon

III\switch of the distributor of a stream of air. Depending on position of the switch air in salon arrives through defined воздуходувы (fig. 1.36) . Dependence of the direction of a stream of air on position of the switch is shown in tab. 1.2.

The stream direction through воздуходувы 3 and 4 (see fig. 1.36 ) can be operated by means of handles of management of their jalousie. The stream direction in the vertical plane changes rotation of the handles located sideways from воздуходувов, in the horizontal plane — moving of the handles located directly on a jalousie. Air to feet moves through воздуходувы 5.

For heating wind and glasses of windows of forward doors execute the following operations:

– establish the switch I (see fig. 1.33 – 1.35 ) in situation 3;

– turn switches II and III clockwise against the stop;

– close a jalousie воздуходувов 3 (see fig. 1.36 );

– adjust the provision of a jalousie воздуходувов 4 so that the stream of air moved to glasses of windows of forward doors.

For prevention of condensation of moisture ("zapotevaniye") on wind and glasses of windows of forward doors execute the following:

– establish the switch I (see fig. 1.33 – 1.35 ) in situation 2 or 3;

– turn the switch II clockwise against the stop (for inclusion of a mode of the maximum heating of air) – the Termotronic system will automatically maintain the set temperature;

– turn the switch III clockwise against the stop (situation)

– close a jalousie воздуходувов 3 (see fig. 1.36 );

– adjust the provision of a jalousie воздуходувов 4 so that the stream of air moved to glasses of windows of forward doors.

For fast warming up of air in salon of the car which has not been equipped with Termotronic system, execute the following operations:

– establish the switch I (see fig. 1.33 ) in situation 3;

– establish the switch II in situation for creation of a demanded temperature mode;

– establish the switch III in situation between symbols and. If in this mode glasses of windows of forward doors "mist over", establish the switch III in situation between symbols and

– close a jalousie воздуходувов 3 (see fig. 1.36 );

– adjust the provision of a jalousie воздуходувов 4.

For fast warming up of air in salon and maintenance of its constant temperature on the cars equipped with Termotronic system, execute the following operations:

– establish the switch I (see fig. 1.34 ) in situation 3;

– establish in demanded situation the switch II (recommended air temperature in salon of +22 °C);

– establish the switch III in situation. In this position of the switch the system of heating works with maximum efficiency.

– close a jalousie воздуходувов 3 (see fig. 1.36 );

– adjust the provision of a jalousie воздуходувов 4.

For salon ventilation by fresh air:

choose position of the switch I (see on fig. 1.33 – 1.35 );

turn the switch II counter-clockwise against the stop — heating is switched off;

establish the switch III in situation;

open a jalousie воздуходувов 3 and 4 (see fig. 1.36 ).

Fig. 1.35. Control panel central air

Air central air (on cars of the corresponding complete set) joins in pressing of buttons IV (see fig. 1.35 ): «norm» – supply of fresh air or «max» – air circulation in salon. At turning on of buttons the control lamps built in in them light up. The system is disconnected by repeated pressing of the button — the corresponding control lamp dies away.

Central air works only at the switched-on fan of the supercharger (the switch I in situation from 1 to 4, see fig. 1.35 ), at the working engine and external air temperature is higher than +5 °C.

For fast cooling of air in salon execute the following actions:

– lift all glasses of windows of doors;

– establish the switch I (see fig. 1.35 ) in situation 4;

– turn the switch II counter-clockwise against the stop — heating is switched off;

– establish the switch III in situation;

– press the max button IV;

– open a jalousie воздуходувов 3 and 4 (see fig. 1.36 ).

At such position of switches air arrives in the conditioner from salon and is quickly cooled.

For decrease in air temperature in salon execute the following actions:

– establish the switch I (see fig. 1.35 ) in any situation from 1 to 4;

– establish the switch II in any situation;

– establish the switch III in any situation;

– press the norm button IV;

– adjust the provision of a jalousie воздуходувов 3 and 4 (see fig. 1.36 ).

At such position of switches air arrives in the conditioner outside (a mode of supply of fresh air) and is cooled.
