Air Conditioning Button
The air conditioner (A/C) cools and dehumidifies the
air inside the cab. Press the A/C button, located in
the center of the temperature control knob, to turn
the air conditioner on and off. See
Fig. 8.3 . The A/C
has three modes:
•
Off
•
Economy (ECO); green LED
•
Full A/C (maximum cooling); blue LED
The ECO mode does not cool the air temperature as
low as the full A/C mode, and can provide fuel sav-
ings.
When using the climate control in full A/C mode (blue
LED illuminated), after 45 minutes the system will
automatically switch to ECO mode (green LED illumi-
nated) to improve fuel economy. Full A/C can be
reset by pushing the A/C button again.
Mode Control Knob
The mode control knob allows the driver to control
the flow of air through the face outlets, the floor out-
lets, the defrost (windshield) outlets, or a combination
of these outlets. See
Fig. 8.4 .
•
Face Mode: Directs all airflow through the face
or instrument panel outlets.
•
Bi-Level Mode: Directs the airflow equally to
the face outlets and the floor outlets.
•
Floor Mode: Directs all airflow through the floor
outlets.
•
Floor/Defrost Mode: Directs the airflow equally
to the floor outlets and the defrost outlets.
•
Defrost Mode: Directs all airflow through the
defrost outlets.
•
All Mode: Directs the airflow equally to the
face, floor, and defrost outlets.
NOTE: There are intermediate modes between
each knob position.
Bunk Override Button
The bunk override button, equipped on sleeper cabs
only, copies the temperature and fan settings from
the cab to the sleeper. See
Fig. 8.4 .
Pressing the bunk override button in either the cab or
the sleeper will copy the current cab HVAC tempera-
ture and fan settings to the sleeper HVAC. An amber
indicator will illuminate when bunk override mode is
activated. When in override mode, the sleeper cli-
mate control panel automatically conforms to the fan
speed and temperature settings on the cab climate
panel at the time the override mode is activated. Fur-
ther changes of the cab climate control settings will
not alter the settings of the sleeper climate control
panel.
The override mode is disabled when the fan or tem-
perature control knob on the sleeper climate control
panel is manually set to a different setting. The over-
ride mode is also disabled when the bunk override
button is pressed to the off position in the cab.
Sleeper Climate Control Panel
The standard sleeper climate control panel has a fan
knob and a temperature control knob with an A/C
button.
If the bunk override button has been activated, the
override mode can be canceled by changing the
sleeper fan speed or temperature setting. The cli-
mate control system will then operate from the
sleeper controls.
