Ventilation, heater and conditioner of air of salon

GENERAL INFORMATION

Airfinal channels

Supply of air via the channels intended for this purpose is regulated depending on the chosen control mode - automatically or manually.

On an illustration places of supply of the air, placed on the dashboard are shown.

On any of channels the heated-up, not heated up or cooled fresh air can arrive.

Management of distribution of air is carried out by the multiitem switch About (heater) or conditioner keys.

Stitched deflectors 3 and 4 can be closed or open the corrugated handles separately located on each side.
The direction of supply of air via stitched deflectors can be regulated both in vertical, and in horizontal the planes.
The conditioner automatically supports a uniform microclimate in all space of salon.

For this purpose the temperature of air arriving on stitched channels, and also its mass expense (quantity) and distribution of air streams automatically changes. In need of this automatic process it is possible to introduce manual amendments.

On the control panel display the conditioner established on the average console, deduces indication of the programmed temperature and fan turns. On the left side of the display there is a key of regulation of temperature, and from the right - a key of regulation of turns of the fan. Regulation of temperature and turns of the fan is carried out by pressing of keys “+” or “-”.

Governing bodies ventilation and heater

And temperature regulator

The temperature can be increased smoothly regulator rotation clockwise.

About the air distributor

The direction of an air stream in space for feet

Stitched channels 5 are open.

For the direction of all stream of air to feet stitched deflectors 3 should be closed.

The direction of an air stream to a windscreen


In this situation the mode air circulation (key D) will not join.

Via deflectors 3 warm air on lateral glasses in addition can move.

Deflectors 1 and 2 are open.

The direction of an air stream via deflectors



Stitched channels 1, 2 and 5 are closed. Air moves via deflectors 3 and 4.

At the given positions of the air distributor some leakage of air via other deflectors always takes place.

D mode of air circulation

In a circulation mode access of air is from the outside blocked, and its volume is distributed in salon around. Thereby hit in salon of the air polluted by exhaust gases is prevented. Movement in this mode should not be too long-term.
In case of a zapotevaniye of glasses press repeatedly a key D for shutdown of circulation or include a mode

Prevention of a zapotevaniye wind and lateral glasses


If at the increased humidity of air, for example, during a rain, glasses mist over, the following option of control of system is recommended:

Establish the switch B in situation II or III.

Regulator And if necessary slightly tighten with calling in a high-temperature range.

The air distributor C establish, depending on requirement, between provisions

Via deflectors 3 warm air on lateral glasses in addition can move.

Regulator And turn clockwise against the stop.
Open stitched deflectors 3.

Normal mode of heating of salon

When glasses will be cleared and in salon the necessary temperature will be established, it is recommended to adjust system as follows:

The switch B in situation II or III.

Regulator And adjust on the necessary productivity of a heater.
The air distributor C in situation

Stitched deflectors 3 are regulated at will.

Ventilation (mode of supply of fresh air)

In the option of control described below via stitched deflectors 3 and 4 not warm fresh air arrives:

The switch B establish in the necessary situation (III corresponds to the maximum intake of air).

Regulator And turn to the left against the stop.

The air distributor C in situation

Open stitched deflectors 3 and 4.

If necessary establish the air distributor C in other situation.

General provisions

For normal work of system of heating and ventilation the air inlet located before a windscreen should not be hammered by snow, ice and foliage.

In order to avoid a zapotevaniye of glasses on small speed the fan should be switched constantly on on low power.

For the termination of hit of the polluted external air in salon press a key D. In order to avoid a zapotevaniye of glasses movement in this mode should not be long-term.

The antidust filter catches the weighed microparticles of external air (for example, a dust, pollen etc.). Establish the switch in situation 0 only in case of pollution outwardly air gases.

Element of the antidust filter replace according to the plan THAT for the purpose of prevention of falling of capacity of a heater.

Governing bodies air conditioner

All modes of the conditioner will join and will be switched off by pressing of keys. At the included mode in the corresponding key the diode burns.

Standard control

After ignition inclusion:

Establish temperature 22°С (71°F) and press the AUTO key.
Such control provides the fastest creation in salon of a comfortable microclimate.

Therefore to recede from it there is a sense only if it is dictated by own health.

AUTO automatic equipment (regular mode)

The temperature, quantity and distribution of air are regulated automatically, by criterion of the fastest achievement and the subsequent maintenance of the necessary temperature in salon. Automatic response to fluctuations of temperature of external air, and also to sun influence is thus provided.

TEMP temperature regulation

The temperature in salon can be set in limits from 18°С (64°F) to 29°С (84°F). At regulator installation in one of the extreme provisions "LO" and "HI", regulations of temperature do not occur. The system constantly works in a mode maximum hlado-or heatproductivity.

Indication of temperature can be switched from Celsius scale to the Fahrenheit scale and back in the following order:

Press and hold a key

Then press a plusovy key of regulation of temperature.

Heating (defrosting of glasses)


The fastest defrosting/release from a zapotevaniye wind and lateral glasses.

The temperature is regulated automatically. The maximum supply of air is carried out mainly on channels 1 and 2.

The pressing of this key switches off a mode of circulation and an economic mode.

Circulation mode



In a circulation mode access of air is from the outside covered, and its volume is distributed in salon around. Thereby hit in salon of the car of the air polluted by exhaust gases is prevented. Movement in this mode should not be too long-term.

At a zapotevaniye of glasses at once include a mode
ATTENTION

In need of short-term shutdown of the compressor of the conditioner, for example, owing to excessive loading of the engine, again press an air circulation key.



ECON economic mode

For economy of fuel it is possible to switch off the compressor. However at the disconnected compressor possibilities of a podderzhivaniye of a comfortable microclimate in salon are limited. If in salon becomes too hot or glasses will mist over, it is possible to turn on again the compressor in ECON or AUTO key pressing.

OFF conditioner switching off


By pressing of this key the conditioner is switched off. Access of external air is blocked.

For turning on of the conditioner press the AUTO key or one of keys of fan/regulation of temperature, the air distributor, or клавшу OFF.

Correction of turns of the fan


In pressing of keys “+” or “-” the turns of the fan set by automatic equipment change. The actual turns are displayed in the form of segment indication of the display.

Keys

it is possible to change the programmed mode of the air distributor. Probably both separate, and the combined manipulation these keys.

If necessary to return to an automatic mode, disconnect the corresponding functions by pressing of these keys separately or AUTO key pressing.

Supply of air to glasses



All consumption of air is realized on channels 1 and 2. Unlike a mode the amount of air does not increase.

Supply of air from the dashboard



All consumption of air is realized with giving via dashboard deflectors 3 and 4.

Supply of air in space for feet



All consumption of air is realized via stitched channels 5 and exits of air channels under forward seats.

Key recognition

The main manual settings of the conditioner are programmed for convenience of using automatically.

At change of settings of the conditioner by other user of your car, after ignition inclusion automatically there is their installation in a starting position according to the parameters programmed on your key.

Necessary condition for this purpose is use by the previous user not yours, and other key of the car. Otherwise there will be a programming of the parameters established by these user on your key.

Therefore when using the car several drivers everyone should use the key for automatic installation of the set parameters of the conditioner.

General provisions


The fan turns on in cold weather only after warming up of cooling liquid to the necessary temperature. The exception makes a mode.

In order to avoid falling warm and hladoproizvoditelnost, and also a zapotevaniye of glasses important that the air inlet before a windscreen was not hammered by snow, ice or foliage.

On cars with automatic transmission, at a sharp troganiye with completely squeezed out pedal of an accelerator, or at anticipatory switching on a low gear (Kick-Down) the compressor of the conditioner is disconnected for some time for realization of full capacity of the engine.

The compressor is disconnected at too high temperature of cooling liquid for ensuring normal cooling of the engine in the conditions of extreme loading.

In cold weather the compressor is automatically switched off. In this case it will not manage to be included and the AUTO key intended for this purpose.

At the switched-on compressor the temperature and humidity of air in salon go down. Thanks to it the zapotevaniye of glasses is prevented.

The conditioner works most effectively at the closed elevating and movable panel крыши* and the lifted glasses.
If, however, air in salon heated up as a result of long parking of the car on the sun, lowering of glasses for short time before turning on of the conditioner can accelerate cooling process.

At high external temperature and humidity from the evaporator the condensed water, forming a pool under the car can drip. This normal phenomenon which is not a sign of depressurization.

The antidust filter catches the weighed microparticles of external air (for example, a dust, pollen etc.). Include a circulation mode at impurity of air exhaust gases.

Element of the antidust filter replace according to the plan THAT for prevention of loss of capacity of the conditioner.

At premature pollution of the filter as a result of car operation in zones with strong air pollution more frequent can be demanded, than THAT is provided by the plan, replacement of a filtering element.

Arriving via stitched channels and distributed then on all salon air is removed through exhaust cracks under back glass. Therefore do not close them clothes subjects, etc. things.

At the slightest suspicion on conditioner damage at once switch off it and check on HUNDRED Audis.
Only after that it is possible to maintain the conditioner again.

For repair of Audi conditioners highly skilled masters and the special tool are necessary.
Therefore at malfunctions of the conditioner address on HUNDRED Audis.
