Temperature Log Recall Mode
The electronic control system is equipped with a temperature history data storage system. This system logs/stores
the average temperature of each individual thermistor every two hours, along with any event indicators (explained
later in this section), that may have occurred. These two-hour periods are referred to as
“indexes”.
Up to 168
indexes can be stored for each compartment, making it possible to observe the preceding fourteen days of the unit’s
temperature history
(each index equals 2 hour temperature average; 2 hours X 168 indexes = 14 days).
After 168
indexes are stored, each new index will bump the oldest index. Index number “1” being the most recent two-hour
temperature average and index number “168” being the oldest. Accessing this temperature history data so it can be
viewed on the LCD is accomplished by initiating Temperature Log Recall Mode.
There are two ways to initiate Temperature Log Recall Mode. One allows viewing of compartment temperature his-
tory only (see below), the other allows viewing of compartment temperature history and evaporator temperature his-
tory (see following page).
To View Compartment Temperature History Only
- Begin with the unit ON. Now, press and hold the desired
compartment WARMER key, then press the UNIT ON/OFF key, then release both keys (See Figure 3-72). The left
display area on the LCD will show average compartment thermistor temperature and in the right display area will be
the index number. The first index number will be “1”, indicating the most recent two-hour temperature average. The
right display area will also flash the thermistor location code at 3 second intervals (See Figure 3-73).

To toggle up through the indexes (from 1 to 168), press the same WARMER key in multiple key strokes (See Figure
3-74). To toggle down through the indexes (from 168 to 1), press the corresponding COLDER key in multiple key
strokes (See Figure 3-75).
