188.8.131.52. Automatic control system of a microclimate
The AUTO switch (the automatic mode)
(see fig. 1.107
|Fig. 1.107. Appearance of the control panel of the automatic air conditioning system: 1 – switch of frequency of rotation of the fan; 2 – switch of the modes of distribution of air; 3 – switch of an obduv of a windshield; 4 – air temperature regulator; 5 – AUTO switch (automatic mode); 6 – conclusion to the air temperature display; 7 – switch of the modes of ventilation of salon; 8 – air conditioner switch; 9 – the OFF switch it (is switched off)
By pressing the AUTO switch (the automatic mode) the system of climate control carries out the following automatic functions (according to the set air temperature in interior of the car):
– regulation of temperature of the air given to salon;
– regulation of frequency of rotation of the fan (amount of the air given to salon);
– switching of the modes of distribution of air;
– switching of the modes of forced ventilation and recirculation of air;
– inclusion and switching off of the conditioner of air;
– switching of operating modes of the conditioner of A/S or A/C ECON air.
The indicator which is built in the button of the AUTO switch.
The burning indicator indicates that the system of climate control functions in the automatic mode.
If the built-in indicator does not burn, the driver manually means changed one or several operating modes of system of climate control (for example, switched the air distribution mode, changed the frequency of rotation of the fan, pressed the switch of the conditioner of air or the switch of an obduv of a windshield). At the same time the system supports the mode set by the driver manually. For the rest, the system of climate control continues to function in the automatic mode.
The OFF switch it (is switched off)
(see fig. 1.107
By pressing the OFF switch the system of climate control is disconnected.
Air temperature is regulated by rotation of the handle: clockwise – increases, and counterclockwise – decreases.
|Fig. 1.109. Adjustment of frequency of rotation of the fan
Seven speeds of rotation of the fan are provided. The chosen frequency of rotation of the fan is reflected in the information display.
The switch of the modes of distribution of air
(see fig. 1.107
By means of the switch it is possible to choose the required air distribution mode.
If the mode is included and air temperature is set at the average level, warm air comes to a zone of an arrangement of legs of the driver and passengers, and more cool goes to salon through the central and side ventilating grates located in the control panel.
Air conditioner switch.
If the system of climate control works in the automatic mode or the fan is switched on, by means of the A/C button it is possible to include or switch off the air conditioner (performing functions of cooling and drainage of air).
The choice between the A/S and A/C ECON modes is carried out automatically. In economy mode (A/C ECO) efficiency of cooling of air and removal of condensate from a windshield decrease. However, use of this mode allows to lower load of the air conditioning system. The conditioner of air can not work if temperature of air approaches 0 °C (the indicator continues to burn even if the system is switched off).
Switch of the modes of ventilation of salon.
You can choose the mode of forced ventilation or the mode of recirculation of air. Press the switch button to choose one of two modes of ventilation of salon.
