70The automatic temperature control system
To turn your EATC on, push the AUTOMATIC
button or any of the six 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 AUTOMATIC, the system will
automatically determine fan speed and airflow
location. If an override button is selected, your
selection determines airflow location only. Fan
speed remains automatic unless you override it by
rotating the vertical thumbwheel located at the
extreme right of the control panel.
To change the temperature in the display window,
select any temperature between65ÊF(18ÊC) and
85ÊF(29ÊC)using the BLUE (cooler) or RED
(warmer) buttons. The Electronic Automatic
Temperature Control will do the rest.

If you want continuous maximum cooling, push the
BLUE button until60ÊF(16ÊC) isshown in the
display window. Your EATC will cool at maximum
and disregard the60ÊF(16ÊC)setting until you
select a warmer temperature with the RED button.
If you want continuous maximum heating, push the
RED button until90ÊF(32ÊC) isshown in the
display window. Your EATC will provide maximum
heat regardless of the90ÊF(32ÊC)setting until you
select a cooler temperature with the BLUE button.
The display window tells you how the system is
operating. It will indicate the selected temperature
and the operating function you have chosen; AUTO
or one of the six manual overrides. It will also
indicate manual (thumbwheel) control of the fan
speed with the
Hsymbol. The display window
with all possible displays and their positions are
shown here. Normally not all are shown at the
same time but are included here to familiarize you
with the names and symbols.
Automatic operationPush the AUTOMATIC 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.

72When in AUTOMATIC 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. In 3-1/2
minutes or less, the fan speed will start to increase
and the airflow will change to the floor area.
If unusual conditions exist (i.e., window fogging,
etc.), the six manual override buttons allow you to
select special air discharge locations. A thumbwheel
allows you to adjust the fan speed to suit your
needs.
Temperature selectionThe RED and BLUE buttons at the upper left of the
Control are for temperature selection. The RED
Button will increase the set temperature and the
BLUE Button will lower the set temperature.
Pressing a button and releasing it will change the
set temperature one degree. Holding either button
in will rapidly change the temperature setting in
one degree increments to either65ÊF(18ÊC)
(BLUE) or85ÊF(29ÊC)(RED). Then, the set
temperature will jump 5 Ê and stop at either60ÊF
(16ÊC)which is maximum cooling or90ÊF(32ÊC)
which is maximum heating. When you select60ÊF
(16ÊC) or90ÊF(32ÊC), the fanwill go to HI speed
for maximum air flow.
The average temperature range used is between
68ÊF(20ÊC) and78ÊF(26ÊC).Changing the
temperature setting by several degrees outside this
range or overriding to60ÊF(16ÊC) or90ÊF(32ÊC)
will not speed up the heating or cooling process.
