EXPLATION FOR MICOM CIRCUIT
1-5. Temperature sensing circuit
1) GR-P247, L247, P207, L207
The above circuits are circuits attached to freezing room sensor or cold storage room sensor for adjusting setting
temperature at the freezing room and cold storage room, ice-making sensor for sensing water temperature in ice-making, or
an evaporator for sensing temperature of a frost removal sensor necessary for frost removal. Short or open status of every
temperature sensor is as follows:
