  Bunk Override Button (on sleeper-cabs only)

  Fig. 1, Mode Control Knob With Bunk Override Button

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..

Pressing the bunk override button in either the cab or the sleeper will 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 or temperature control knob on the sleeper climate control panel is manually set to a different setting. The override mode is also disabled when the bunk override button is pressed to the off position in the cab.
