Bunk Override Button (on sleeper-cabs only)
Fig. 1, Mode Control Switch With Bunk Override Button
Note: There are intermediate modes between each switch position.
Bunk Override Button
The bunk override button on sleeper cabs allows the driver to control the sleeper temperature and fan settings from the cab. See Fig..
Press the bunk override button to copy the current cab HVAC temperature and fan settings to the sleeper HVAC. An amber indicator will illuminate when bunk override mode is activated. When in override mode, the sleeper climate control panel automatically conforms to the fan speed and temperature settings on the cab climate panel at the time the override mode is activated. Further 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 switch or temperature control switch on the sleeper climate control panel is manually set to a different setting or when the bunk override button is pressed to the off position.
