(*¹) To re-arm alarms connected to the hours of operation you need only reset the hours on the device
to zero.
(*²) These alarms cause the unit to shutdown bringing it to the status OFF from alarm
Note. To activiate the alarms derived from the digital contacts you need to set to a value
greater than zero the relative position for which the dedicated digital inputs will be
connected. If the position is zero the alarm is not managed. A position may be repeated only
once; it is not possible to manage the same position like “OR” for additional alarms.
