Connection macro Cn008 - PID control with analog reference
NOTICE
If a negative setpoint for the PID control is desired, change the setpoint and feedback
wiring as needed.
When you switch to Hand mode from PID control mode, P2200 becomes 0 to disable the
PID control. When you switch it back to Auto mode, P2200 becomes 1 to enable the PID
control again.
