CONTROLLER FOR LOW-TEMPERATURE BOX
Document Type and Number:
Japanese Patent JP2983818
Kind Code:
B2
Abstract:
PURPOSE: To reduce the cost by simplifying a display of a set temperature of a defrost reset temperature and a display in the case of checking an apparatus.
CONSTITUTION: A controller 50 comprises a DEF reset temperature sensor 24 for detecting a temperature of a cooler, a defrost heater 30 for defrosting the cooler, a DEF reset temperature set variable resistor 32 for setting a defrost reset temperature of the cooler, a microcomputer 21, and a display unit 40 having a plurality of LEDs l-8 aligned in parallel. The microcomputer 21 emit lights from the LEDs l-8 of the unit 40 by a binary notation thereby to display a set temperature set by the resistor 32.
