Set Temperature Offset

This feature is added to allow cool down or warm up of the vehicle's HVAC system. The offset value will allow the displayed set temperature to be different from the commanded set temperature from -5° to +5°.

To perform set temperature offset:

1. Enter diagnostics.
2. Display IPC Override Output.
3. Press the COOLER or WARMER button to the desired set temperature.
4. To overwrite the value in memory, hold the ECON and DEF buttons for three seconds.
