Control
Control action
• PID action (with auto-tuning function)
o 0
o 0
o 0
o 0
• PI action: When derivative time is set t
• PD action (with manual reset function): When integral time is set t
• P action (with manual reset function): When derivative and integral time are set t
• ON/OFF action: When proportional band is set t
