Interface communication timeout: If no communication message is received from the User
Interface for more than the timeout delay, the unit will be stopped and the alarm will be activated.
If this parameter is set to 0, the communication timeout is ignored (sec)
NOTE: If P523=0 the communication timeout is ignored

RC backlight timeout: The RC backlight is switched OFF when no key is pressed within a
configured period of time:
0 = Backlight always OFF (disabled)
1 = 15 seconds
2 = 30 seconds
3 = 1 minute
4 = 2 minutes
5 = 5 minutes
