Control action
• PID action (with auto-tuning function)
• PI action : When derivative time is set to 0
• PD action (with manual reset function) : When integral time is set to 0
• P action (with manual reset function) : When derivative and integral times are set to 0
• ON/OFF action : When proportional band is set to 0
Setting ranges of the control parameters :
OUT proportional band : 0.0 to 110.0% (ON/OFF action when set to 0.0)
Integral time
: 0 to 1000 seconds (Off when set to 0)
