5 Technical Descriptions
5.1. Temperature control for each compartment
5.1.1. FC temperature control
The compressor is turned on and off detecting the FCC temperature.
Operation: The setting temperature “-25
°
C” to “-17
°
C”, 9 levels change
Detection: FCC, ATC sensor
1. When power supply is turned on, FC temperature is displayed on the panel PCB by reading FC setting data of microcomputer
memories. The data is written in memory area of microcomputer, 5 seconds after FC setting change. After that, FC tempera-
ture is controlled by setting FC temperature of the panel PCB.
The FC setting data is memorized, though the power supply of this product is turned off. The setting temperature is fixed, after
the time to have set temperature change passed more than 5 seconds.
2. The setting temperature
The temperature, when it set on -21
°
C
The OFF/ON temperature value corresponding to each ATC temperature is as shown in the next graph.
5.1.2. PC temperature control
PC damper is controlled by the PCC temperature.
1. When power supply is turned on, PC temperature is displayed on the panel PCB by reading PC setting data of microcomputer
memories.
The data is written in memory area of microcomputer, 5 seconds after PC setting change. After that, PC temperature is con-
trolled by setting PC temperature of the panel PCB. The PC setting data is memorized though the power supply of this appli-
ance is turned off.
