The automated air conditioning system (conditioner)

General information

In detail in a basic equipment of all models the automated air conditioning system functions only at the working motor. At the choice of the profitable mode (EC), the cooling system does not work.

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

Insignificant fluctuations of temperature around certain point clear up at influence of sunlight and Gefällen of temperature of external air.

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

The step of change of temperature has to be big not too.

The attached filter installed to the entrance highway guarantees protection of salon against penetration in it of dust and flower pollen of plants.

General comments after functioning of the K/W system

Functioning of the K/W system can lead to formation of condensate underground cars, - education under saparkowannym by car of a small pool in hot weather should not cause concern.

In a hot sunny weather prior to the movement it is necessary to air it is necessary the car interior heated in the sun.
They follow that opening of ventilation remained open indoors between the back shelf and back glass of the car.

In the winter you clean prior to the movement of snow a lattice of air receipt before a car windshield.

In case of a vytecheniye of coolant functioning of K/W will be also system automatically stops is switched to the profitable mode.

For activization of the mode you at the same time press the buttons in the top corners of the control panel, - the light-emitting diodes installed in buttons have to ignite. For the device in komfortabelen salon of room temperature (22 °C) you at the same time press the buttons and. The following information will be displayed:

Intensity of transfer and distribution of an air current in this mode will be automatically regulated. Buttons of the choice of the modes of temperature on deflektorach of the central air channels of the panel of devices have to be otschaty.

Auftauens mode of glasses

Completely you open cuts of pass of side glasses of the panel of devices.
For activization of the Auftauens mode of glasses you press the button, - the control light-emitting diode constructed in the button has to ignite. The following information will be displayed:

Shutdown of the Auftauens mode of glasses is made by the repeated pressure upon the same button.

The mode of removal of condensate from glasses

For bystry removal of condensate from glasses you exclude the profitable mode or the mode of the closed address, then you activate the automatic mode of simultaneous pressure of buttons (control light-emitting diodes have to ignite) and by means of buttons you choose the mode of transfer of air to the top part of salon manually. The following information will be displayed:

Do not forget completely, to open pass cuts to the parties puffed panels of devices.

Profitable mode

For activization of the profitable mode you press the EU the button, - the control light-emitting diode constructed in the button has to ignite.

In the profitable mode such functions of system as cooling and drainage of air become switched off.
Shutdown of the mode is made by the repeated pressure of the same button.

Compulsory choice of the direction of distribution of an air current

The choice of the direction of distribution of an air current is made by means of control panel buttons. Press the buttons, up to the screen confirmation on the necessary switching will be removed. In a following example the mode of transfer of air on is chosen, glaziers of a motive half of salon and in legs of the forward passenger blowing:

For activization of transfer of air sopla of the panel of devices is central you press one of the deflektorow buttons.

Return to the automatic mode is made by means of pressure of the CAR buttons.

Compulsory choice of intensity of transfer of air

The choice of 7 bystry modes of functioning of the fan can be made manually by means of the switch of keys, - the confirming information is output by a graphic view of the screen (darkening of sections of the wedge-shaped indicator):

By means of the same switch shutdown of K/W is made. Continue to press the switch, up to the screen the message of "OFF" will be displayed and transfer of air to salon will stop:

Shutdown of the Konditionierung system for long time can lead to sapotewaniju of glasses.

Activization of K/W can be made by means of pressure upon one of buttons or, or to pressure upon the section "+" of the switch of keys.

Mode of use of other heat of the motor

Heating of salon can be made during even certain time after a motor break due to use of other heat. Activization of the corresponding mode is made by means of the button on the control panel, - the control light-emitting diode installed in the button has to ignite.

Before the appendix of the mode you turn a key in the ignition lock in situation 0 or 1, or you pull out it from the lock. It is also necessary to cover it a section of pass of sopla/puffed of the back air channel
In the mode regulation of intensity and the directions of transfer of air is automatically made.

The necessary condition of use of the mode is a sufficient level of freight of the battery.

The exception of the mode is made automatically after a signal of hours of switching for about 30 minutes, at key poworatschiwanii in the ignition lock in situation 2, and also at remarkable immersion of level of freight of the battery.

Mode of the address of air

Activization of the mode of the address of air is made by means of the button of the K/W control panel, - the control light-emitting diode installed in the button has to ignite. In this mode shutdown of transfer is made in salon of fresh air. This function allows to prevent a meeting in a car interior of sagasowannogo or unpleasantly smelling air.

Long use of the closed address, leads to sapotewaniju of glasses and increases in spertosti of air, therefore recommended, only as a last resort and for rather short time to accept this mode, for example, at the movement after the territory from sadymlennoj or the polluted atmosphere. Hardly need of isolation of salon falls down, transfer of fresh air has to be updated.

Repeated pressure upon the button of the switch allows to restore air transfer.

Automatic shutdown of the mode of the closed address is also provided after a signal of hours of switching: approximately it is higher for 30 minutes at temperatures of external air of +5 °C, 5 minutes it below at temperatures of 5 °C and 5 minutes in is profitable (EU) the mode of functioning of the Konditionierung system.

At high temperatures of external air activization of the mode of the closed address automatically is made, - approximately each 30 minutes will be served in salon a share of fresh air. Besides, dangerous increase in concentration brings to automatic activization of the closed mode in entrance current of Monooxids of carbon or as nitrogen oxides (NOH) provided that the mode and temperature of external air is switched off it below +7 °C.

Accession to the highway of air of access of salonnogo of the filter

On pressure upon the button of the K/W control panel accession is made to the highway of air of access of the Konditionierung system is stuffed filter salonnogo absorbent carbon. The fact of activization of the filter is confirmed by wear of the switch of a control light-emitting diode installed in the button.

Accession of salonnogo of the filter strongly allows to limit concentration in the air course of access of harmful components and to prevent penetration into a car interior of unpleasant smells.

For the purpose of preservation of the set intensity of transfer of air at connection of the filter of change of the fan
K/W automatically raise.

Increase in concentration in external Monooxids air of carbon (C) or nitrogen oxides (NOX) leads to automatic activization of the mode of the closed address (see above).

Activization of the modes and Auftauens of glasses () leads to automatic shutdown of salonnogo of the filter.

In need of the bystry warm movement / cooling of salon it is also necessary to switch off it is necessary the filter.

Heating of back glass

Heating of back glass functions only in situation 2 keys in the ignition lock. Activization of a heating element of back glass is made by means of the button on the K/W system control panel (watch an illustration 19.3), - the control light-emitting diode installed in the button has to ignite.

During a winter season you delete before application of heating from a glass naled and snow.

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

Automatic shutdown of heating is made after a signal of hours of switching for about 12 minutes.

Shutdown of heating of back glass can happen also at simultaneous activization of a large number of consumers of the electric power, and also at remarkable immersion of level of freight of the battery, - the control light-emitting diode installed in the button will begin to blink. With restoration of level of effort the heating element is automatically activated.
