-2-8 Temperature Compensation & Overcooling/Undercooling Compensation Circuit
1. Refrigerator Temperature Compensation
2. The temperature compensation for refrigerator compartment is in the following table:
NOTE
: This circuit is designed to input the necessary temperature compensation values into the MICOM. This adjusts the
refrigerator temperature, which is different in each model.

Table of Temperature Compensation by adjusting the
resistance (difference from the current temperature)
e.g., If the refrigerator compensation resistance
(RCR) is changed from 10K (the current resistance)
to 18K (the adjustment resistance), the temperature
of the refrigerator rises 33.8¡F(+1¡C).
