Devices of ensuring comfort

System of automatic heating and air conditioning (ACC)

General information

The control unit (To/in) is presented by heating and air conditioning systems on an illustration. On the display located over the block, information on the current parameters of these systems is displayed.

The control unit and the display of systems of heating and To/in

1 — Buttons of adjustment of temperature on the left side
2 — the Switch of an automatic mode
3 — Buttons of adjustment of speed of rotation of the fan
4 — Buttons of manual control by air distribution
5 — the Switch of heating of back glass and external mirrors

6 — the Switch of a mode of air circulation
7 — the To/in Switch
8 — the Switch of system of automatic heating and To/in
9 — Buttons of adjustment of temperature on the right side

For achievement of the best result from ACC system it is necessary to close all windows and the roof hatch. Air gets through a lattice of a fairing of a windscreen and gets to salon, passing through the filter and if the heater, through a heater radiator is included. Air leaves salon through apertures in the back shelf, and then through lattices on the right and at the left before a rear bumper.

The ACC system independently selects the working parameters for maintenance in salon of the car of the established temperature. At modification manually in one of parameters by means of the corresponding switch or a regulator, this parameter is not regulated any more by automatic equipment while other parameters continue to steal up automatically. For work of system the following sensors are used:

  • Sensor of temperature of external air;
  • The temperature sensor in salon;
  • Sunlight sensor;
  • Two sensors of temperature of an air mix (in the bottom forward deflectors).

Arrangement of sensors of system of automatic heating and To/in

1 — the temperature Sensor in salon
2 — the sunlight Sensor


Do not cover the sunlight sensor since thus the system of automatic heating and air conditioning can work not correctly.

For supply of air in salon deflectors by means of which it is possible to regulate the direction and intensity of an air stream are used. Maximum efficiency of system is reached at completely open deflectors.

Temperature adjustment

The salon of the car is divided into 2 temperature zones: place of the driver and place of passengers. The system of automatic heating and To/in allows temperature regulation in a range from 15 to the 27th hail. Besides, there are following modes:

In the HI mode:

  • The maximum heating is provided;
  • Air is directed on a windscreen and to feet;
  • If the circulation mode was chosen, it is disconnected;
  • The fan works at the maximum speed.

In the LO mode it is provided:

  • The maximum cooling (at inclusion of the ECON mode joins To/in) is provided;
  • Air is directed on the dashboard;
  • The mode joins;
  • The fan works at the maximum speed.

On the party of the passenger it is possible to choose the HI or LO mode only if the same choice is made on the party of the driver.

Description of buttons of management of ACC system

AUTO

  • The temperature, air distribution, turns of the fan and supply of air are regulated automatically;
  • The To/in compressor is switched off at temperature drop below 0 hail. also joins at excess the 5th hail.;
  • At engine start at external temperature from 0 to the +5th hail. To/in it is included;
  • By pressing the AUTO button all manual adjustments are cancelled;
  • By repeated pressing the AUTO button on the display automatically set installations are displayed;
  • At engine start the ACC system works in the AUTO mode, irrespective of the established program.

ECON

  • The compressor is switched off, arriving air is not cooled;
  • The temperature, distribution of air and turns of the fan are regulated automatically.

At deduction of this button (programming of II) To/in joins at achievement of external temperature more the 13th hail.

OFF

  • The ASS system (the fan, To/in and a heater) is switched off;
  • Distribution of air is fixed in actual situation;
  • It is possible to choose a mode of circulation manually;
  • By repeated pressing the AUTO button the ACC system passes to an automatic mode;
  • By repeated pressing the OFF button the system comes back to control mode manually.

Switch of heating of back glass and external mirrors

Heating of back glass and external rear-view mirrors copes manually. Disconnect heating at once as soon as in it there is no need.

Heating is disconnected automatically in 2-10 minutes depending on temperature of external air or if tension of the battery falls below 10 V.Sistemu ASS it is possible to program so that heating will automatically join, if at the same time the temperature of external air is lower the +5th hail., and the temperature in salon is lower the +10th hail (see programming of II).

Switch of a mode of air circulation

Supply of external air is regulated automatically, providing optimum cooling, but can join/be switched off also manually. The mode of circulation does not change qualitatively composition of air, and it can be included not to allow penetration into salon of unpleasant smells.

At deduction of this button (programming of II) circulation joins at speed of the car below 10 km/h and is switched off at speed below 30 km/h, except for that case when the ECON function is programmed according to the program II.

Buttons of adjustment of speed of rotation of the fan

  • By pressing these buttons speed of rotation of the fan gradually changes;
  • At ignition inclusion the fan works at small speed until the engine will not be started;
  • If speed of the fan "0" is chosen, the To/in compressor is switched off and on the display there is «ECON» inscription.

Buttons of management of air distribution

Single pressing of the button

Mode обдува glasses

At inclusion manually a mode обдува glasses the zapotevaniye is removed from all glasses (the air stream to back lateral windows is blocked) because:

  • The fan works at high turns;
  • Air goes to deflectors;
  • The temperature is regulated in a normal mode;
  • The mode of circulation is disconnected;
  • Heating of back glass and external mirrors joins.

Having blown in glasses it is included till that time, the new choice, however function of heating is not made yet is disconnected automatically in 5-10 minutes.

Double pressing of the button

Air goes to a windscreen without increase in speed of rotation of the fan and without heating inclusion. For return to earlier made installation press the AUTO button.

Other buttons

By pressing of buttons for inclusion of the combined modes of distribution of air on the display there are corresponding pictograms. The direction of streams of air in various modes is specified on illustrations.

Start in cold weather

The ACC system at first chooses a mode of heating of glasses, the maximum heating and low speed of the fan. With engine temperature increase air goes to feet and speed of the fan increases.

When the temperature in salon reaches the programmed value, speed of the fan decreases and occurs having heated up to automatically certain levels.

System start in hot weather

The ACC system chooses supply of air to deflectors on the dashboard with high speed of the fan and turns on the To/in compressor if the ECON button is not pressed.

If the temperature of air exceeds the 30th hail., approximately through 45 with the circulation mode if the system needs it for achievement of the chosen temperature can join. When the temperature in salon comes nearer to programmed, speed of the fan decreases to automatically certain level.
