HEATING, VENTILATION AND AIR CONDITIONING (HVAC) 1A–81
Automatic Air Conditioning System
General Description
Using a variety of sensors, this automatic heater and air
conditioner accurately senses outside air temperature,
solar radiation quantity, evaporator’s blowing
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-diagnoisis 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.
