(2) Temperature control
The blowing air temperature is controlled by the temp actuator and the set temperature can be checked
via the LCD display.
Manual control
The discharge air temperature is controlled by the temperature control dial. The driver can select one
of the 31 levels.
Auto control
When pressing the AUTO switch, "AUTO" is shown on the display and the fan speed and air distribution
mode are adjusted automatically to keep interior temperature to the set temperature. In full AUTO mode,
the FATC receives various signals such as the indoor temperature, ambient temperature, engine coolant
temperature, sunlight, from different sensors to control the A/C compressor, mode actuator, intake
actuator, temp actuator, blower motors, etc. to keep indoor environments fresh.
Max. cooling/heating control (AUTO mode)
If the temperature is set to the lowest level (Lo) or highest level (Hi), the system will go into the maximum
cooling or maximum heating mode regardless of the sensor signals.
