2.4.1. Systems of heating, ventilation and an air conditioning

At correct use of possibilities of systems of heating, ventilation and an air conditioning in car salon comfortable conditions of stay are provided and is excluded запотевание glasses.


Management дефлекторами ventilating lattices


Adjustment by a deviation of the air stream submitted to salon through the central and lateral air lines of the panel of devices

Adjustment of a direction and intensity of giving of air through nozzles of the central and lateral air lines of the panel of devices is carried out by means of special wheel regulators, and also by deployment actually assemblages дефлекторов (see an illustration above). Thus to position there corresponds the closed condition of a nozzle, and to position — opened.


The control panel functioning of systems of ventilation, heating and an air conditioning


The control panel functioning of systems of heating, ventilation and an air conditioning

The central air can be activated only at the working engine.


In hot weather do not leave in closed salon of the car of pets, children and sick adults!
In order to avoid a stagnation of air do not include for a long time a mode of the closed circulation!


Automatic mode functioning К/В (climate control)


Cooling / of drainage of air submitted to salon (AUTO)

In the given mode air central air will maintain constant temperature in car salon, simultaneously carrying out a speed control of functioning of the fan and a direction of distribution of an air stream.

Press button AUTO on control panels (the Control panel functioning of systems of heating, ventilation and an air conditioning see an illustration), — on the display screen the inscription of the corresponding maintenance should be highlighted.

By means of the switch of a choice of a temperature mode choose temperature which the system should support.

The most comfortable the temperature in area 24С is considered.

Further the central air will start to maintain temperature automatically in car salon at the set level, carrying out thus necessary updatings of intensity and a direction of giving of air.


Mode of economic heating of salon (ECON)

Mode ECON is not intended for removal from condensate glasses.

The given mode is used only for warming up of air submitted to salon.

 PERFORMANCE ORDER

  1. Press button ECON on system control panels (the Control panel functioning of systems of heating, ventilation and an air conditioning see an illustration), — on the display screen the inscription of the corresponding maintenance should be highlighted.
  2. By means of the switch of a choice of a temperature mode (see in the same place) choose temperature which the system should support. In case of need automatically intensity and a direction of giving of air will be corrected also.

Do not expose temperature below temperature of external air, differently serviceability of functioning of system will be broken.


Mode of removal from condensate glasses

 PERFORMANCE ORDER

  1. Press button DEF on control panels (the Control panel functioning of systems of heating, ventilation and an air conditioning see an illustration), — on the display screen the inscription of the corresponding maintenance should be highlighted.
  2. By means of the switch of a choice of a temperature mode choose the demanded temperature.
  3. For removal of hoarfrost or a condensate from lateral aspect of glasses choose by means of the switch the maximum high-speed mode of functioning of the fan of a heater.

The choice of mode DEF at temperature of external air above-2S leads to automatic activation of a central air and switching-off of a mode of the closed circulation, - for the purpose of acceleration of process of removal of a condensate external air will start to move in salon.

  1. As soon as glasses will be cleared, press button AUTO for return of system to an automatic mode of functioning.


Hand control mode


Choice of a high-speed mode of the fan

Switching of high-speed modes of the fan is made by means of the switch located in the right top corner of the control panel.

For return to an automatic mode of functioning of system press button AUTO.


Choice of a mode of air circulation

The choice of a mode of air circulation in salon is carried out by means of the button, — activation of a mode of the closed ventilation leads высвечиванию on the screen of the display of the corresponding pictogramme. Repeated pressing of the same button allows to renew giving in salon of fresh external air.

The mode of the closed circulation usually gets out at movement in strongly dusty or загазованной districts, and also in case of need fast остужения air in salon the conditioner.

At long use of a mode of the closed circulation there is air stagnation in car salon.


Choice of a direction of distribution of air

The choice of a direction of distribution of air is carried out by means of push-button switch MODE (functioning of systems of heating, ventilation and an air conditioning) the Control panel see the control panel system functioning an illustration, — on the display screen corresponding symbols will be serially highlighted.

Air giving is carried out only on obverse level through дефлекторы the central and lateral air lines of the panel of devices.

Air giving goes on obverse level and to foot wells.

Air giving is carried out only in foot wells.

Air moves on obverse level, in foot wells and on having blown in a windscreen.


System switching-off

For system switching-off press button OFF (the Control panel functioning of systems of heating, ventilation and an air conditioning see an illustration).


Councils about use of systems of ventilation, heating and air conditioning

At the cold engine and low temperature of external air air giving in foot wells can be blocked for a while from 0 till 126 seconds, — as soon as the cooling liquid will get warm, blocking should act in film automatically.

Temperature maintenance in salon at the set level is carried out at the expense of its monitoring by means of built in the panel of devices of the gauge — do not put on the panel in a gauge installation site any subjects.


The salonnyj filter

The salonnyj filter is intended for clearing of the car of external air submitted to salon of a dust, pollen, a dirt, etc. Replacement of a filtering element салонного the filter should be made according to the Schedule of routine maintenance of the car (Routine maintenance see the Head).

Sign of pollution of a filtering element салонного the filter is appreciable decrease in intensity of giving of air, and also легкозапотеваемость glasses at a working heater or air central air.
