DESCRIPTION
| WARNING | To avoid injury from accidental air bag deployment, read and carefully follow all AIR BAG SAFETY PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM procedures in AIR BAG RESTRAINT SYSTEMS article. |
The A/C-heater system automatically adjusts passenger compartment temperature via control unit integrated with A/C-heater control panel. (Схема №1) The A/C-heater control unit regulates heater operation through an electromagnetic water valve. The electromagnetic water valve controls flow rate through heater core.
Air temperature is regulated by mixing varying ratios of cold and heated air through a cable operated temperature mixing flap. Temperature and air distribution for driver's side and front passenger's side can be controlled separately. All outlets can supply heated, cooled, or fresh air according to temperature setting. (Схема №1)
System uses 5 input sensors: interior temperature sensor, exterior temperature sensor, left heater core temperature sensor, right heater core temperature sensor, and evaporator temperature sensor. Temperature sensors continuously input information to A/C-heater control unit. The A/C-heater control unit processes sensor signals and adjusts system temperature accordingly.
Vehicle is also equipped with a Residual Heat Utilization (REST) function. (Схема №1) This function allows the interior of the car to be heated when engine is turned off. The system will automatically direct heated air to windshield, side windows, and footwell.
