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