Description:
The Minimum and Maximum Idle Shutdown Temperature settings allow the flexibility of a defined temperature range where the engine will always shutdown along with temperature ranges where the driver can override the shutdown, allowing the use of air conditioning or heating. The Allow Idle Shutdown Override parameter must be programmed to “Outside Temperature Based” for these parameters to be programmed.
Available:
All on-highway engines covered in this handbook.
Range:
Advantages:
The Outside Temperature Based Shutdown saves fuel by allowing idle only when necessary for driver comfort.
Disadvantages:
If the Idle Shutdown time is programmed for a long time (more than an hour) and the temperature drops in to the “Always Shutdown” range the engine would shutdown and could wake the driver.
Recommendations:
Program the Minimum setting to a value where it would be necessary to use the heater to be comfortable and the Maximum setting to a value where it would be necessary to use the air conditioner to be comfortable.
