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.
