Changing the display from farenheit to
celsius
To change the temperature display from
Farenheit to Celsius, depress the MAX A/C and
V F-DEF at the same time and hold them
down for about a second. To change back to the
original setting, repeat the process. If the battery
is disconnected, the display will revert to
Fahrenheit and must be reset to Celsius.
Automatic operation
Press the AUTO button and select the desired
temperature. The selected temperature and
AUTO will be shown in the Display window.
The EATC will automatically heat or cool to
achieve the set temperature. Under normal
conditions, your EATC will need no additional
attention.
The AUTO temperature display
When in AUTO and weather conditions require
heat, air will be sent to the floor. But a feature is
included in your EATC to prevent blowing cold
air to the floor if the engine coolant is not warm
enough to allow heating. The EATC will direct
the airflow to the windshield at low fan speed.
In 3-1/2 minutes or less, the fan speed will start
to increase and the airflow will change to the
floor area.
