Sensor Temperature Conversion

If the red Freezer LED plus one other LED is on (refer to Section 10.1.4), this indicates that a sensor
temperature is being displayed. Temperatures are read as follows:
Each temperature scale LED has a numerical value. The values from left to right are: 32, 16, 8, 4, 2, 1 and
0.5. If the LOCK LED is off, it is a positive temperature, and if the LOCK LED is on, it is a negative
temperature.
To obtain the temperature of any of the sensors:
1. Obtain the binary code of the sensor reading (refer to Sections 10.1.4 to 10.1.4.6).
2. Add up the binary number indicated by the temperature indicator LED pattern (see Figure above).
