WIRING SYSTEM
Heater and Air Conditioning (Automatic)
General Description
Using the signals from a variety of sensors, the full
automatic heater and air conditioning system accurately
senses outside air temperature, solar radiation quantity,
evaporator’s blowing temperature, heater core water
temperature and interior temperature. These signals
enable the control unit to automatically control blow
temperature and air blow 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 the system to
switch to the manual control mode.
The self-diagnosis function of the control unit allows the
unit to access and diagnose failed parts easier and
quicker.
Refer to Air Conditioning System in HVAC System.
