2.6. Automatic conditioner of air (ASS)

The ASS system maintains the set temperature in salon irrespective of air temperature.

The value of temperature displayed on the display is not the actual value of temperature in salon: the system considers such factors as the movement of air, humidity, direct solar radiation and so forth, and creates the climate corresponding to feeling of comfort at the set temperature.

ASS system control panel


Usually temperature is established in the range of 19-23 °C depending on habits of the people who are in the car and their clothes.

It is the best of all to change temperature step by step, to 1 °C.

In the course of warming up of salon it is recommended to close average nozzles of the forward panel if you do not want that warm air blew in the person. Temperature can be established in the range of 17-27 °C. It is possible to set two special modes: HI - the maximum heating and the maximum ventilation, and LO - the minimum cooling and the minimum ventilation.



Having blown in a back door

The system has four sensors

— The air temperature sensor (the signal arrives from the traveling EDU computer)
— The air temperature sensor in salon (it is located under hours)
— The sensor of solar radiation (it is located over the forward panel)
— The sensor of temperature of the air given to salon (it is located in a heater)

In order to avoid inexact work of the ASS system do not block foreign objects the sensor of solar radiation located on the center over the forward panel.

Sensor of solar radiation

Start in cold weather:

Originally the system includes heating of a back window and rear-view mirrors, chooses the modes of defrosting, maximum heating and operation of the fan on small turns.

For maintenance or improvement of distribution of the cooled or warmed up air at certain climatic/road conditions the system can quickly (no more than 30 seconds) to direct air to floor nozzles.
In process of warming up of the air directed to salon, the frequency of rotation of the fan increases and the most part of air moves through floor nozzles. At achievement of a preset value of temperature in salon the frequency of rotation of the fan and heating decreases automatically and brought to constant level.

Start in hot weather:

Originally the system directs fresh air through nozzles of the forward panel with the maximum frequency of rotation of the fan and includes the EXPERT system (if the ECON key was pressed).

For maintenance or improvement of distribution of the cooled or warmed up air at a certain climatic situation in salon the system can quickly (no more than 30 seconds) to direct air to floor nozzles.

If temperature of external air is above 27 °C, in one minute the system will set the recirculation mode.

At achievement by temperature in salon of a preset value the frequency of rotation of the fan automatically decreases by constant level.

Ventilating nozzles



Dark shooters — warm air
White shooters — cold air

Installation of desirable temperature

 PERFORMANCE ORDER

1. Include ignition
2. By means of the corresponding keys establish desirable value of temperature. The button under the display serves for the choice of a scale of degrees Celsius or Fahrenheit.
3. The established value of temperature remains in memory of the microprocessor even at switching off of ignition. At the following inclusion of ignition the microprocessor will automatically establish earlier chosen value of temperature.


The established value of temperature in salon





Increase in temperature





Reduction of temperature

 

1 - Automatic control

Adjustment of temperature, air distribution, frequency of rotation of the fan, heating of a back window and rear-view mirrors is carried out automatically. Conditioning joins automatically if temperature of air is above +5 °C. Pressing of the AUTO key cancels action of all of the modes which are earlier set manually. Manual installations of those modes, join at the following starts of the engine.

2 - Switching off of the compressor of the conditioner

At the choice of this mode the conditioner does not work. Adjustment of temperature, air distribution, frequency of rotation of the fan, heating of a back window and rear-view mirrors is carried out automatically.

3 - Switching off of the ASS system

By pressing this key the system is disconnected. For inclusion it is necessary to press the AUTO key or once again to press the OFF key. In this case all modes set manually will be reproduced.

4 - Electrical heating

Heating of glass of a back window and rear-view mirrors joins and switched off automatically, but can be included manually. In this case it is disconnected automatically in 10-11 minutes. At any time the mode can be switched off manually.

5 - Having blown in windows of back doors

Operation of fans of an obduv of glasses of back doors is regulated automatically, synchronously with operation of the main fan. However these fans can be switched off manually.

6 - Recirculation

Recirculation of air joins and switched off automatically, but can be switched on and off manually. The recirculation mode poorly influences quality of air in salon.

7 and 8 - Smooth increase and reduction of frequency of rotation of the fan

For achievement of desirable speed of rotation of the fan it is necessary to hold a key pressed.
The luminescence of an average light-emitting diode means that the fan works in the mode of automatic control of turns.
The luminescence of two other light-emitting diodes means that the operating mode of the fan was set manually: increase in turns of the fan - burns the top light-emitting diode, reduction of turns of the fan - the lower light-emitting diode burns.
Adjustment of turns of the fan from lower to the top limit takes about 8 seconds.

9 - Defrosting mode

At manual installation of the mode the system performs operations on fight against frosting and fogging of glasses: turns of the fan increase, the stream of air goes on having blown in a windshield and side glasses, heating of glass of a back window joins. If earlier the recirculation mode was set, it is switched off.

The mode of defrosting works until other mode is set, however heating of a back window is switched off approximately in 10 minutes.

Repeated pressing a key of the mode of defrosting sets earlier operating mode.

10 - Defrosting/floor

Air moves on having blown in a windshield and to a floor. The small amount of air moves also through nozzles of the forward panel.

11 - Air supply to a floor

Air moves to a floor. The small amount of air moves also on having blown in a windshield.

12 - Air supply to a floor and via the forward panel

Air moves via the forward panel and to a floor. A small amount of air moves also on having blown in a windshield.

13 - Air supply via the forward panel

Air moves only via the forward panel. A small amount of air moves also on having blown in a windshield.

14 - The established value of temperature

Programming of the ASS system

By means of programming of the ASS system there is an opportunity to bring the modes chosen manually in memory. Further these modes will be automatically set at inclusion of ignition. Let's note that it is necessary to make a pause not less than 4 minutes after switching off of ignition before testing results of programming.

 PERFORMANCE ORDER

1 Choose the necessary mode.

 
2 At the same time press and release keys (at the same time the ASS display and light-emitting diodes will begin to blink).

Deleting of the program from memory

For cancellation of the program brought in memory it is necessary to press and release at the same time the OFF and AUTO keys (at the same time the ASS display and light-emitting diodes will begin to blink).

Useful tips

If the accumulator was disconnected or discharged, the ASS system needs repeated calibration.

Calibration

If power supply of the ASS system was interrupted, the system needs repeated calibration.


For calibration of system hold pressed the AUTO keys + a key until the light-emitting diode about a key lights up that means course of processes of calibration and self-testing of system. Then light-emitting diodes will begin to be lit one by one on the right.


In the course of calibration on the display it is displayed or 0 that means lack of malfunctions in system, or the figure (1-5) which is a code of the malfunction found in system. After the end of calibration on the display the established value of temperature will be displayed.

Process of calibration takes about 30 seconds.

Special climatic conditions

Frosting and fogging of glasses arises only at special climatic conditions. If similar occurred it is possible to recommend the following:



1 — Choose the AUTO mode and establish temperature of 21 °C.
2 — Set the mode of defrosting.
3 — Increase fan turns.
4 — Increase temperature in salon.
