Automated central air of air (climate control)

General information

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

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

Insignificant fluctuations of temperature round the established point speak influence of sunlight and temperature drops of external air.

The design of system allows to support an individual microclimate from both parties of salon.

The step of change of temperature should be not too big.

The connected filter built in an entrance path 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.

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.

In a forward part of salon air moves in four main directions: on obverse level of the driver and the forward passenger (central and in 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 to the right) and the direction (nozzle assembly is rotary) leaving a stream. Two push-button switches built in between the central deflectors allow to include/switch off independent heating/cooling of a leaving stream.

In a base mode all buttons are wrung out.

Deflectors snuffled a path of supply of air in a back part of salon can have one of two designs, depending on that, the mode of conditioning is provided here or not.

The control panel To/in with the digital information display built in it is located with functioning in the top part of forward section of the central console.

Mode of automatic functioning

The mode of automatic functioning of system is base. For activation of a mode press at the same time buttons in the top corners of the control panel, - the light-emitting diodes built in buttons should light up. For installation in salon of comfortable room temperature (22°С) press at the same time buttons and. On the screen of the display the following information will be deduced:

Intensity of giving and distribution of an air stream in this mode will be automatically regulated. Buttons of a choice of temperature modes on deflectors of the central air lines of the dashboard should be wrung out.

Mode of defrosting of glasses

Completely open sections of lateral glasses of the dashboard through passage.
For activation of a mode of defrosting of glasses press the button, - the control light-emitting diode built in in the button should light up. On the screen of the display the following information will be deduced:

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

Mode of removal of condensate from glasses

For fast removal of condensate from glasses switch off an economic mode or a mode of the closed circulation, then activate an automatic mode in simultaneous pressing of buttons (control light-emitting diodes should light up) and by means of buttons manually choose a mode of supply of air in the top part of salon. On the screen of the display the following information will be deduced:

Do not forget to open completely sections of the lateral through passage snuffled dashboards.

Economic mode

For activation of an economic mode press EU button, - 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.

Compulsory choice of the direction of distribution of an air stream

The choice of the direction of distribution of an air stream is made by means of control panel buttons. Press buttons until on the screen of the display confirmation on demanded switching will not be deduced. In the example given below the mode of supply of air is chosen on having blown in glasses of a driver's half of salon and in feet of the forward passenger:

For activation of supply of air through the central nozzles of the dashboard press one of buttons of deflectors.

Return to an automatic mode is made by pressing of the AUTO buttons.

Compulsory choice of intensity of supply of air

The choice of one of seven high-speed modes of functioning of the fan can be made manually by means of the keyboard switch, - confirming information in a graphic look is displayed the display (blackout of sections of the wedge-shaped indicator):

By means of the same switch shutdown To / is made continue to press the switch Century until on the screen of the display the message of "OFF" and supply of air in salon will not be deduced will stop:

Central air shutdown for a long time can lead to a zapotevaniye of glasses.

Activation To/in can be made by a way of pressing one of buttons or, or pressing section «+» the keyboard switch.

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 residual heat. Activation of the corresponding mode is made by means of the button on the control panel, - the control light-emitting diode built in the button should light up.

Before inclusion of a mode turn a key in the ignition lock in situation 0 or 1, or take it from the lock. Also it is necessary to block section of a nozzle through passage / snuffled a back air line
In a mode adjustment of intensity and the directions of supply of air is made automatically.

Necessary condition of use of a 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.

Air circulation mode

Activation of a mode of air circulation is made by means of the To/in control panel button, - 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 temperatures of external air is higher +5°С, in 5 minutes at temperatures is lower 5°С and in 5 minutes in economic (EU) a mode of functioning of central air.

At high temperatures of external air activation of a mode of the closed circulation is made automatically, - approximately each 30 minutes in salon the portion of fresh air will move. Besides, to automatic activation of the closed mode gives dangerous increase of concentration in an entrance stream of monooxide of carbon (WITH) or some nitrogen (NOH) oxides provided that the mode and temperature of external air is disconnected is not lower +7°С.

Connection to the inlet air highway of the salonny filter

By pressing the button of the To/in control panel connection to the inlet air highway of central air of the salonny filter filled with absorbent carbon is made. The fact of activation of the filter proves to be true operation of the switch of a control light-emitting diode built in the button.

Connection of the salonny filter allows to limit sharply concentration in an inlet air stream of harmful components and to prevent penetration into salon of the car of unpleasant smells.

For the purpose of preservation of the set intensity of supply of air at filter connection fan turns
To/in automatically raise.

Concentration increase in external air of monooxide of carbon (WITH) or oxides of nitrogen (NOX) leads to automatic activation of a mode of the closed circulation (see above).

Activation of modes and defrosting of glasses () leads to automatic shutdown of the salonny filter.

In need of fast warming up/cooling of salon the filter also should be disconnected.

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 button on the To/in system control panel (see an illustration 19.3), - 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 12 minutes.

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.
