Figure 3-58. SERVICE Indicator Illuminates - Indicates Unit was switched OFF During that Index Period by
Pressing UNIT ON/OFF Key
Figure 3-60. Double Dashes ( - - ) Displayed Instead of Temperature for Several Consecutive Index Periods -
Indicates Bad EEPROM on Control Board. Board Must be Replaced
NOTE: Double dashes will also be observed when in Manual Compartment Disable Mode. Only when double
dashes are observed in Temperature Log Recall Mode for several consecutive indexes
should the control board be
replaced.
NOTE: If Manual Compartment Disable Mode has been activated during any of the 168 indexes, average tempera-
tures will continue to be logged. No event indicator will appear with these temperatures.
NOTE: If the unit was in Showroom Mode during any of the 168 indexes, average temperatures will continue to be
logged. No event indicator will appear with these temperatures.
NOTE: If the unit was switched OFF by pressing the UNIT ON/OFF key during any of the 168 indexes and there
was still 115V AC supplied to the control board, the average temperatures will continue to be logged. This means
temperatures would be expected to rise and the SERVICE indicator would be present in all indexes in which the unit
was switched OFF.
NOTE: Temperature Log Recall Mode will end 20 seconds after the last key stroke.
Temperature Log Event Indicators
The diagrams below illustrate possible event indicators that may be observed while in Temperature Log Recall
Mode. (See Figures 3-57 through 3-60)
Figure 3-57. “bl” Indicates Index is “blank” - No Temperature has Been Logged Yet
(Only possible within first 14 days of unit operation, or after new control board is installed during service)
