FULL AUTOMATIC AIR CONDITIONING SYSTEM

GENERAL DESCRIPTION

Using a variety of sensors, this full automatic heater and air conditioner accurately senses outside air
temperature, solar radiation quantity, evaporator’s blowing temperature, heater core coolant temperature
and interior temperature, then enters these data to the automatic heater/air conditioner control unit
(equipped with the built-in micro-computer). The data provided to the control unit enables to automatically
control blow temperature and blow air quantity, turn on or off the compressor and switch the blow port as
well as switching between the fresh air intake and interior air circulation.
Resetting the automatic function allows you to switch to the manual control mode.
The self-diagnosis function of the automatic heater and air conditioner control unit (with the built-in micro-
computer) allows the unit to access and diagnose a failed part easier and quicker.
