With the ECC all you have to do is basically set the temperature control knob at the desired temperature level, and the system takes care of the rest. The ECC is a highly advanced system that monitors cab and outdoor temperatures, evaporator temperature, vehicle speed engine revolutions per minute and several other parameters. Its thermostat controls the cab temperature, air distribution, airflow, and fresh air intake accordingly.
Having said that, the cabin climate control always remains in your hands. At the click of a button, as easily as you put it on, the automatic mode can be switched off.
