Mercury 1996 Grand Marquis Manual page 95

To change the temperature in the display
window, select any temperature between 65˚F
(18˚C) and 85˚F (29˚C) 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 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
RED button. If you want continuous maximum
heating, push the RED 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 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
H symbol. 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.
