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.
