7D-6 AUTOMATIC CONTROL HVAC SYSTEM

SYSTEM BASIC FUNCTION

Set Temperature Control
When you set the setting temperature using the
temperature control switch, the FATC receives the
various input signals from sensors including the
information of inside air temperature, ambient
temperature, coolant temperature and sun loads etc..
The FATC uses this signals to control automatically
the A/C compressor, the mode door, the I/A door, air
mix door and blower motor etc.
Airflow Control
For setting at Full AUTO, it is possible to control the
blower motor operation both manually and
automatically in order to adjust the airflow according
to the set temperature.
Manual Control
When you push the blower switch, you can control the
blower motor manually and it increases or decreases
each step by moving the switch to HI/LO. (with the
ignition ON)

Automatic Control
Td value can be determined by the set temperature
value and Td value is set to the target voltage of the
blower motor simultaneously. The blower motor can
shift without step.
Abbreviation: Td (Thermal Demand) : Td value is
the default for automatic control of the automatic
temperature control and allows it to control the set
temperature calculating the differences between
inside air temperature and ambient temperature.

Vent Rate Control By Heating Operation
When the temperature of the engine coolant is low or
it's difficult to obtain the desired hot air in winter, the
system controls to prevent the cold airflow from the
outlet due to the cold air give a negative effect to the
heating performance.
Therefore vent step is fixed 1st on blower AUTO step
until the coolant sensor detects above 20 ° C and also
the blower step increases gradually according to going
up the coolant temperature. When the coolant
temperature goes up above 40 ° C, the heating
operation stops.
Vent Rate Control By Cooling Operation
When the air inside the resonance duct is hot in summer,
after the system keeps the low vent rate (1st) operating
for 5 seconds and discharges the hot air to the
windshield side (Def Mode), the system starts to control
normally in order to avoid for the passengers contacting
the hot air.
