UAZ PATRIOT Operation Manual page 67

Blowing ventilation of the interior is performed via the same
channels, when the handle 1 (Fig. 3.12) is arranged at maximum
counter clockwise position. Drawing ventilation is performed
via air holes in the rear roof liner and inner panel of the tail
gate apertures, via ventilation grille with valves and rolled down
door window.
Control panel operation mode (Fig. 3.12)
"Manual" operation mode is the main mode of the control
panel.
When this mode is switched on, the control panel scans the
condition of the control elements (rotary switches 1, 2 and 3)
and, depending on their positions, works in accordance with the
prescribed operation algorithm, determines the condition of the
recirculation flap, A/C switch, position of the rotary switches.
In accordance with this data, the control panel generates and
transmits control signals for:
- speed control unit of the heater fan;
- switching the air conditioner on/off;
- motoreducer of the recirculation flap;
- motoreducer of the air current distribution flap and choke
flap;
Besides its own control elements, the control panel interacts
with a number of external switches, namely: "AUTO" mode
switch, "Intensive windscreen heating" mode switch, recirculation
flap control switch, A/C switch.
"Intensive windscreen heating" mode is turned on by a switch
, transmitting a signal to the control panel. The control
panel generates and transmits the control signals necessary for
switching the heating-and-ventilating unit and climate control
unit into this mode to the actuating elements.
In this mode, the control panel changes the position of the
air distribution flap to "To the window" position, air damper to
position, which corresponds to the 8th switch position 1 (Fig.
3.12). However, rotation speed of the climate control unit fan
corresponds with 8th positions of the switch 3. In this mode,
the control panel does not react to changes in positions of the
rotary switches.
