Hold function

9.1
This function allows to interrupt a cycle: red display visualizes
is stopped. It is possible to modify setpoint pressing
To start this function proceed as follows:
• Enter confi guration and select
• With cycle in progress press

Automatic Tuning

9.2
This procedure allows the user to have a precise regulation also without
knowledge of PID regulation. Selecting
controller check process oscillations and modifi es PID parameters if the
diff erence between process and setpoint values is greater than value on

Manual Tuning

9.3
This procedure allows user a greater fl exibility on deciding when to update
PID parameters. To enable this function, select
