1_ Temperature compensation table by adjustment value (difference value against current temperature)
Ex) If you change compensation resistance at a refrigerator (RCR1) from 10 k_-2(current resistance) to 18 k_-2(modified
resistance), the temperature at the refrigerator will increase by +1 °C[+1.8°F].
