When the Out-of-Range Temperature is configured ON, the microprocessor indicates out-of-range when the tem-
perature has been within the tolerance band at least once, and then goes outside the tolerance band for 45 min-
utes. If this condition occurs, the unit will shut down or shown an alarm depending on the setting of CNF9.
For set points at or below +10°F (-12.2°C) frozen range, the unit is only considered out-of-range for temperatures
above set point.
Code/English Messages
The description messages of the functional parameters, unit status, and alarms can be displayed in English or
Codes through this function selection. The two choices are displayed as ENGLISH or CODES. With this parameter
set to CODES, all display descriptions are set to their code display. This parameter does not change due to this
selection. Refer to each section for the alternate display description.
Manual Glow Override
The auto start glow time can be manually overridden through this function. The message is displayed as NORM
GLOW or ADD GLOW. If the ADD GLOW selection is entered, the control adds 30 second of glow to the glow
times listed in
Table
3–8. This feature must be selected before the three start attempts have been completed. At
higher ambients, this override only affects the second or third start attempt. The add glow time is deselected when
the engine starts or fails to start. This parameter does not change due to the Code vs English selection.
Alarm Reset
Alarms can be reset through this function. The messages are displayed as ALARM RST or ALARM CLR. If the
ALARM RST is displayed there is at least one alarm present. Pressing the ENTER key clears all the alarms pres-
ent. If the ALARM CLR is displayed, there are no alarms present. This parameter does not change due to the code/
English selection. See
Section 3.12
