5-2-9. Storing temperature compensation and over-cool/under-cool cut compensation circuit
(1) Storing temperature compensation
u
This is the circuit to input the temperature compensation level required for adjusting storage temperature at the left or
right compartment of the lid or drawer.
u Temperature compensation table by adjustment of resistance value (difference against current temperature)
Ex) If you change the resistance of compensation at the lid left compartment (RCL) from 10K
Ω
(current resistance) to
18K
Ω
(adjusted resistance), the storage temperature in the lid left compartment will be increased by 1°C .
