5 Technical Descriptions
5.1.
Temperature control for each compartment
5.1.1.
FC temperature control
The compressor is turned on and off and 3-Way Valve Controlled, detecting the FC 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 micro-
computer memories. The data is written in memory area of microcomputer, 5 seconds after FC setting change. After
that, FC temperature 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 table.
3. OFF/ON temperature according to FC temperature setting
The OFF/ON temperature corresponding to each FC temperature setting is as shown in the following tables.
*: TFOFF and TFON that exist in the following table are considered the temperature calculated by
the OFF/ON temperature value at -21
C
setting.
5.1.2.
PC temperature control
The compressor is turned on and off and 3-Way Valve Controlled, detecting the PC temperature.
Operation: The setting temperature “1
C”
to “7
C
”, 7 levels change
Detection: PCC, ATC sensor
1. When power supply is turned on, PC temperature is displayed on the panel PCB by reading PC setting data of micro-
computer memories.
The data is written in memory area of microcomputer, 5 seconds after PC setting change. After that, PC temperature
is controlled by setting PC temperature of the panel PCB. The PC setting data is memorized though the power supply
of this appliance is turned off.
