3-2-10. KEEPING TEMPERATURE COMPENSATION AND TOO COLD/ TOO WARM CUT COMPENSATION CIRCUIT
(1) Keeping Temperature Compensation Circuit
u This circuit is used for entering the required level of temperature compensation into MICOM to adjust keeping
temperature at the upper, middle and lower compartment.
u Temperature compensation table by adjustment of resistance value (difference value against current temperature).
Ex) Temperature at the middle compartment increases by +1°C if changing compensation resistance at the middle
compartment (RCT) from 10K (current resistance) to 18K (corrected resistance).
