serial with the parameter P233 Add 2233.
Available functions are:
0 = Nessuna funzione
No associated functions.
1 = Start / Stop
Start / Stop of the controller by digital input with impulse command.

If the input is active, the regulation is enabled.
NOTE: With the regulator in STOP the alarms remain active.
