Control Operation for
Loops 1 and 3 (Pin 4)
Pin 4 selects forward (cooling) operation (ON) or reverse (heating) operation
(OFF) for control loops 1 and 3.
Control Operation for
Loops 2 and 4 (Pin 5)
Pin 5 selects either forward (cooling) operation (ON) or reverse (heating)
operation (OFF) for control loops 2 and 4.
Control Method (Pin 6)
Pin 6 selects either ON/OFF control (ON) or PID control (OFF).
• If ON/OFF control is being used, the width of the hysteresis loop (hys-
teresis) can be set to adjust the control sensitivity.
• If PID control (PID control with two degrees of freedom) is being used,
the PID constants can be set automatically with the autotuning func-
tion.
Initialize EEPROM
Settings (Pin 7)
If pin 7 is ON, the settings in EEPROM will be initialized to their factory
defaults when the Temperature Control Unit is turned ON or restarted. (Initial-
ize EEPROM only when a Hardware Check Error has occurred. Refer to
5-1-3
Alarms Detected by the Temperature Control Unit
for details.)
Transfer EEPROM
Settings (Pin 8)
If pin 8 is ON, the settings in the Temperature Control Unit’s EEPROM will be
transferred to the corresponding words in the CPU Unit’s DM Area when the
Temperature Control Unit is turned ON or restarted. Turn ON pin 8 if you want
the Temperature Control Unit to operate with settings stored in EEPROM.
The settings in the Temperature Control Unit’s RAM can be saved to
EEPROM by turning ON the corresponding loop’s Save Bit. Refer to
2-5-3
Memory in the Temperature Control Unit
for details on the settings.
