Mercury 1996 Sable Manual page 124

To turn your EATC on, press the AUTO button
or any of the six manual override buttons along
the bottom of the control.
To turn your EATC off, press the OFF button.
When the system is off, the Display window will
be blank (dark).
If you select AUTO, the system will
automatically determine fan speed and airflow
location. If a manual override button is selected,
your selection determines airflow location only.
Fan speed remains automatic unless you
override it by pressing either side of the FAN
speed button located at the extreme left of the
control panel.
To change the temperature, select any
temperature between 65˚F (18˚C) and 85˚F (29˚C)
by pressing the a or b side of the TEMP
button. The EATC will display the selected
temperature.
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.
If you want continuous maximum cooling, press
the b side of the TEMP button until 60˚F (16˚C)
is shown in the display window. Your EATC
will cool at maximum and disregard the 60˚F
(16˚C) setting until you select a warmer
temperature with the a side of the TEMP
button. If you want continuous maximum
heating, press the a side of the TEMP button
until 90˚F (32˚C) is shown in the display
window. Your EATC will provide maximum
heat regardless of the 90˚F (32˚C) setting until
you select a cooler temperature with the b side
of the TEMP button.
