Temperature Log Recall Mode
The electronic control system logs/stores the average temperature of each individual thermistor every thirty (30) min-
utes, along with any possible event indicators. These thirty-minute periods are referred to as "indexes". Up to two-
hundred forty (240) indexes can be stored for each thermistor, which is five (5) days of temperature history. After
two-hundred forty (240) indexes are stored, each new index bumps the oldest index, with index number "240" being
the oldest thirty minute temperature average. Accessing and viewing this temperature history data in the LCD is
accomplished by initiating Temperature Log Recall Mode.
There are two ways to initiate Temperature Log Recall Mode. One allows viewing of historical average temperature
readings from the compartment thermistors only, the other allows viewing of historical average temperature readings
from all thermistors.
Temperature Log Recall Mode for Compartment Thermistors Only - With the unit ON, press and hold the
desired compartment WARMER key, then the POWER key, then release both keys (See Figure 3-68). The LCD will
now display compartment temperature at left and the Index number at right, with the thermistor location code flash-
ing at three (3) second intervals in the first index digit area ("r" = Refrigerator, "F" = Freezer - See Figure 3-69).
Pressing the WARMER key will toggle up through the indexes, from 1 to 240 (See Figure 3-70), while pressing the
COLDER key will toggle down (See Figure 3-71).
NOTE: Temperature Log Recall Mode will end 20 seconds after the last key stroke.
