Channel 16 - Coolant Overheat Switch

If engine coolant temperature rises over 247°F (120°C) the overheat switch will close and complete a ground signal to the control panel head. This will prevent the A/C compressor from operating.


To activate the display:





- If necessary, press the OFF button while pressing the OUTSIDE TEMP button.
- Press the WARMER button until '16 is displayed.
- Press the COOLER button to display the switch position.
