In manual mode, users can operate air volume control knob to
set the right air volume, air volume change from 1 to 7 level. In
automatic mode, blower speed is part of the automatic control
logic. Blower speed is not limited to the level 7 in manual mode,
but the LCD only displays 7. The bar in the display shows the
nearest fan speed.
4. Manual Adjustment / Automatic Adjustment
of the Wind Patterns
Automatic air-conditioning controller provides two kinds of
manual and automatic modes for users to choose out of wind.
By adjusting the face / feet / windshield of the throttle to control
the wind patterns. Blowing head and legs blown difference is
that the temperature distribution of feet in order to provide a
more warm air, and to provide more cool air head to ensure the
driver is always in a comfortable driving environment. The
temperature range of the distribution will be subject to the
impact of vehicle space.
Automatic air-conditioning, heater and evaporator controller
uses temperature sensors to determine the temperature of gas
mixture.
In manual mode, users can choose 5 wind modes:
1. Blow Facial
2. Two-way (Blow surface and blow feet)
3. Blow Feet
4. Hybrid (Blow feet and defrost)
5. Defrost
LCD displays appropriate wind mode icons. When the air-
conditioning system uses two DC motor control ventilation
mode, the air-conditioning controller can affect the air flow
distribution. The wind pattern corresponding to the angle and
voltage of the following table:
Manual

Blow Facial 21.17 0.29
Two-way (Blow
surface and blow
feet)
112.94 1.57
Blow Feet 180.70 2.51
Hybrid (Blow feet and
defrost)
286.58 3.98
Defrost 341.64 4.75
In automatic mode, the wind model is the automatic control
logic, as part of the wind mode is automatically selected by the
controller. When the wind mode button to operate the system
from the automatic mode to manual mode. In order to achieve
the degree of comfort, head to reach a certain temperature, foot
temperature is higher than the head temperature 4-6°C
(39-43 ºF). Air-conditioning system may result in certain
restrictions in certain special cases, the level of comfort not be
achieved. Air-conditioning control module to choose a time
closest to the pattern displayed in the LCD.
5. Inside and Outside Circulation Control
User can select inside and outside circulation mode:
1. Outside circulation mode, the outside circulation throttle
open, inside circulation throttle close.
2. Inside circulation mode, the inside circulation throttle open,
outside circulation throttle close.
Inside and outside circulation control button is used for manual
adjustment. In automatic mode, the throttle is controlled by the
system automatically. When inside and outside circulation
control button is operated, the system will enter the manual
mode. According to inside temperature, automatic control logic
automatically controls the throttle work. Users can switch
modes between inside and outside circulations. when the
inside circulation continues 20min, the system will
automatically switch to the outside circulation 2min, and then
back to inside circulation. Manually switch to the outside
circulation, the system will not interfere with this operation.
