Optimized Idle User Manual Continuous Run Condition and Extended Idle Condition Under normal conditions, the engine will cycle on and off to keep the interior at the desired temperature. Two automatic conditions which help keep the operator comfortable and reduce engine cycling are described in the next sections. Continuous Run Condition This condition allows the engine to run continuously if the outside temperature parameter exceeds the parameterized limits (hot and cold) and the thermostat set point can not be met (factory default is 25°F (-4.00°C) for cool mode and 90°F (32°C) for heat mode).
When the thermostat is in the Continuous Run Condition, the temperature icon will flash along with the heat or cool icon. Extended Idle Condition NOTE: If Optimized Idle enters the extended idle condition, it may be an indication that the heat or cool setting on the thermostat does not match the vehicle heating or cooling system setting. It could also be an indication of low freon, blockage in the heater system, or system tampering. If the Continuous Run Condition is not needed and the thermostat set point is not met within 45 minutes, the engine will shut down for 15 minutes, restart and run for 15 minutes.
This 15 minute on and off cycle will continue until the thermostat set point is reached or until the thermostat is turned off. All information subject to change without notice. 9 DDC-SVC-MAN-0019 Copyright © 2016 DETROIT DIESEL CORPORATION
