Automatic Control
For the most efficient operation, you should set the
system temperature and press AUTO. The system will
select the best fan speed and airflow settings to keep you
comfortable. The air conditioning compressor will run if
the outside temperature is above 40
_F (4_C). You may
notice a delay of two to three minutes before the fan
comes on at start up in cool weather.
Temperature Control
The TEMP switch sets the temperature for the entire
system when the light on the DUAL button isn’t lit.
If the DUAL button light is lit, this master temperature
control sets the temperature for the driver only. Press the
up arrow to raise the temperature and press the down
arrow to lower the temperature. The display will show
your selection for a few seconds, then the outside
temperature will be displayed. If you push the AUTO
button, the system will control the fan speed and airflow.
The driver’s temperature and passenger’s temperature
settings will be automatically maintained even if manual
overrides have been selected except for settings at 60
_F
(15
_C) and 90_F (32_C).
Setting the temperature to 90
_F (32_C) will lock control
in full hot, direct air to the floor, and increase the fan speed
to high. The system will not return to automatic temperature
control until the temperature setting is lowered.
Setting the temperature to 60
_F (15_C) will lock control
in full cold, recirculate interior air, direct air to outlets
on panel and increase blower speed to high. The system
will not return to automatic temperature control until the
temperature setting is raised.
Passenger’s Temperature Control
The PASSENGER CONTROL buttons with the arrows
adjust the temperature on the passenger’s side so it is
warmer or cooler than the temperature for the driver’s
side. Push the DUAL button so that the indicator light is
lit. Press the right arrow button to raise the temperature.
Press the left arrow button to lower the temperature.
The display will not show the passenger’s temperature,
only that of the driver. Indicators in the passenger
control section will show passenger’s side temperature
relative to the driver’s set temperature.
D The amber light indicates the same temperature as
set for the driver.
D The red lights indicate a warmer temperature than
that of the driver.

that of the driver.
