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)

Derivative time

: 0 to 300 seconds (Off when set to 0)
