Initiate Temperature Log Recall Mode To View Compartment and Evaporator Temperature History - Begin
with the unit ON and in Diagnostic Mode (See Figure 3-63). While in Diagnostic Mode, toggle through the readings
until the desired thermistor temperature is displayed on the LCD (See Figure 3-64). Now, press the WARMER key
for that compartment and the UNIT ON/OFF key simultaneously (See Figure 3-65). The left display area on the LCD
will show average thermistor temperature and in the right display area will be the index number “1” indicating the
most recent 2-hour temperature average (See Figure 3-65). The right display area will also flash the thermistor
location code at three second intervals (See Figure 3-66).
To toggle up through the indexes (from 1 to 168), press the same WARMER key in multiple key strokes (See Figure
3-67). To toggle down through the indexes (from 168 to 1), press the corresponding COLDER key in multiple key
strokes (See Figure 3-68).
