Automated central air of air (climate control)

General information

Entering into a standard complete set of some models the automated central air of air functions only at the working engine. At a choice of an economic mode (АСoff), the system of cooling does not work.

Transition to the chosen temperature mode always is made with the maximum possible speed.

Built in an entrance air path of system the connected filter provides protection of salon against penetration in it of a dust and pollen of plants.

General comments on To/in system functioning

Functioning of To/in system can lead to formation of condensate under the car bottom, - education under the parked car of a small pool in hot weather should not cause concern.

In a hot sunny weather before a start of motion it is necessary to air the salon of the car heated up by the sun.

Watch, that ventilating openings in space between the back shelf and back glass of the car remained open.

In the winter before a start of motion clean from snow an air inlet lattice before a car windscreen.

In case of leakages of a coolant functioning To/in automatically stops and the system is switched in an economic mode.

Governing bodies

Supply of air in salon of the car carries out on a network of air lines of system of the ventilation, terminating in the equipped deflectors nozzles.

Scheme of distribution of an air stream and elements of management of a target stream of a forward air path

In a forward part of salon air moves in four main directions: on obverse level of the driver and the forward passenger (the central and lateral deflectors of the dashboard), on having blown in a windscreen (forward deflectors of the dashboard), on having blown in lateral glasses (lateral deflectors) and in foot wells (the bottom air lines).

Target nozzles of forward air lines settle down on the dashboard and in foot wells of salon.

Design of zhalyuziyny deflectors of days off snuffled air lines of obverse level allows to operate intensity (the full perekryvaniye of a nozzle is made by a regulator povorachivaniye against the stop up) and the direction of leaving streams (a rotary element nozzle assembly is).

Forward assembly of management by functioning To/in is located in the top part of console section of the dashboard.
Zhalyuziynye deflectors snuffled a path of supply of air in a back part of salon have a rotary design, adjustments of a pressure of air and stream distribution in the vertical direction are carried out with located directly under assembly of deflectors of the switch of management.

Mode of automatic functioning

The mode of automatic functioning of system is base. For activation of a mode press the AUTO button of the central switch of the control panel, - the light-emitting diode built in the button should light up. The choice of a demanded temperature mode is carried out by rotation of a rotary regulator of the central switch (built in a regulator ring the being shone segment serves for indication of the chosen value).

Having appointed a comfortable temperature mode, press the AUTO button and hold it pressed during not less than 3 seconds, - the system will pass to a mode of automatic maintenance of the chosen installation.

The design of a control system provides possibility of programming of a base temperature mode. Transfer a rotary regulator of the central switch to the discretion chosen on yours situation (for example, 21°С), then press the AUTO button and hold it pressed during about 10 seconds.

Manual adjustment of intensity and directions of distribution of air

Intensity and the direction of distribution of air can be exposed manually by means of rotary regulators of lateral switches (the control light-emitting diode of the AUTO mode will go out), - the chosen temperature mode does not change.

Intensity of supply of air can change within 5 steps of high-speed modes of functioning of the fan.

The choice of the direction of distribution of air provides the following possible options:

Supply of air on having blown in a windscreen
Supply of air on having blown in glasses, on obverse level and in foot wells
Supply of air in foot wells and on obverse level through lateral nozzles of the dashboard
Supply of air on obverse level

Return to an automatic mode can be made by pressing the AUTO button (the being shone segments which have been built in rings of regulators should go out), - make sure of serviceability of activation of a control light-emitting diode of an automatic mode.

Mode of removal of condensate from glasses

For fast removal of condensate from glasses press the button, - the control light-emitting diode built in in the button should light up. Thus the system automatically provides maximum having warmed and in productivity of the fan, supply of air on having blown wind and lateral glasses (through lateral nozzles of the dashboard, - do not forget to open completely their nozzles through passage and to develop in a demanded way rotary deflectors) and shutdown of supply of air in a back part of salon.

Adjustment of all other installations, except for function of electroheating of back glass, for the period of activation of a mode is blocked.

For mode shutdown rather repeatedly to press the same button, or on the AUTO button.

For condensate removal from an external surface of a windscreen it is necessary to choose a mode of supply of air on having blown in glasses () and to activate screen wipers.

Mode of the closed air circulation

Activation of a mode of the closed air circulation is made by means of the bottom button of the left switch of the K/V forward control panel, - the control light-emitting diode built in the button should light up. In this mode giving shutdown in salon of fresh air is made. This function allows to prevent hit in salon of the car of zagazovanny or unpleasantly smelling air.

Long use of the closed circulation, leads to a zapotevaniye of glasses and increase of a spertost of air therefore it is recommended to include this mode only in case of need and for rather short time, for example, at movement on the district with the filled with smoke or polluted atmosphere. As soon as need of isolation of salon disappears, supply of fresh air should be renewed.

The repeated pressing the button of the switch allows to restore supply of air.

Also automatic shutdown of a mode of the closed circulation on a timer signal is provided: approximately in 30 minutes at included To/in, or in 5 minutes at switched off К/В.

At high temperatures of external air activation of a mode of the closed circulation is made automatically and not accompanied by inclusion of a control light-emitting diode of the button of the switch.

Economic mode

At a choice of an economic mode К/В compressor shutdown is made.

For activation of an economic mode press the ACoff button of the central switch, - the control light-emitting diode built in in the button should light up.

In an economic mode such functions of system, as cooling and air drainage are disconnected.

Shutdown of a mode is made by repeated pressing of the same button.

Mode of use of residual heat of the engine

Heating of salon can be made during even some time after an engine stop at the expense of use of the power unit of residual heat accumulated in the mass. Activation of a mode is made by means of the ACoff/REST button of the central switch of the forward control panel, - the control light-emitting diode built in the button should light up.

Before inclusion of a mode of use of residual heat of the engine (REST) turn a key in the ignition lock in situation 1.

At the activated mode adjustment of intensity and the directions of supply of air is made automatically.

Necessary condition of use of the REST mode is sufficient level of a charge of the storage battery.

Switching off of a mode is made automatically on a timer signal approximately in 30 minutes, at a key povorachivaniye in the ignition lock in situation 2, and also at appreciable decrease in level of a charge of the storage battery.

Shutdowns of supply of air in a back part of salon

Shutdown of supply of air in a back part of salon can be made by means of the bottom button of the right switch of the forward control panel, - the control light-emitting diode built in in the button should light up, and management from the back panel is blocked.

For restoration of supply of air it is necessary to press the same button repeatedly back, - the control light-emitting diode should go out, and the back control panel will be switched in a mode of automatic functioning (sections through passage snuffled open).

Heating of back glass

Heating of back glass functions only in situation 2 keys in the ignition lock. Activation of a heating element of back glass is made by means of the top button of the right switch of the K/V forward control panel, - the control light-emitting diode built in the button should light up.

In a winter season before inclusion of heating remove from glass наледь and snow.

The heating element of heating of back glass consumes a lot of electric power therefore it is not necessary to activate it for a long time.

Automatic shutdown of heating is made on a timer signal approximately in 6-17 minutes, depending on temperature of external air and speed of movement of the car.

Shutdown of heating of back glass can occur also at simultaneous activation of a large number of consumers of the electric power, and also at appreciable decrease in level of a charge of the storage battery, - the control light-emitting diode built in the button will start to blink. With restoration of level of tension the heating element is activated automatically.

The back switch of management of functioning of the automated To/in system

The back switch built in the central part of the control panel located on a back face wall of the central console it is direct under deflectors of a back air line. From both parties from the To/in switch individual switches of regulators of window regulators of back doors are located.

Switch of management of air conditioning of a back part of salon

Mode of automatic functioning

Activation of an automatic mode is made by means of the AUTO button of the back switch equipped with the built in control light-emitting diode.

At the included automatic mode central air of air provides automatic maintenance of a temperature mode in a back part of salon according to the installation chosen by means of a regulator on the К/В forward control panel.

Manual adjustment of intensity and directions of distribution of air

Intensity and the direction of distribution of air can be exposed manually by means of lateral keyboard regulators of the back switch (the control light-emitting diode of the AUTO mode will go out). The temperature mode chosen from the forward panel remains invariable.

The high-speed mode of functioning of the fan is regulated by the left keyboard regulator, the distribution direction in the vertical plane – right.

Return to an automatic mode can be made by pressing the AUTO button, - make sure of serviceability of activation of a control light-emitting diode of an automatic mode.
