At the end of the list, the screen is shown to reset the alarm and
add the event to the alarm log (Data Logger). Press Alarm for 3 s to attempt to reset all of the alarms:
1. if the cause of the alarms is no longer present, they will
be successfully reset and the light on the red button
will go off ;
2. if the alarms cannot be reset, the light on the Alarm but-
ton stays on steady, indicating the alarm has been
acknowledged.
To clear the alarm log, access screen Xe01. On the
second row, it is possible to clear the event counter for
requiring manual reset of semi-automatic alarms.

• Ac56 - frost protection: warning and alarm delay;
• Ac60 - low supply temperature: threshold, alarm delay at start-up and in steady operation;

See the Parameter table for the complete list.
12.3 C ontatti generici di ingresso e uscita di allarme
For greater installation fl exibility, k.air features three generic alarm inputs and three signal outputs. These contacts are always
available, simply associate an activation channel using the I/O confi guration menus Wb03 and Wb04.
The following inputs are available:
• Unit stop alarm, the unit is stopped immediately without completing the shutdown procedure
• Generic alarm, the unit is stopped after completing the shutdown procedure
• Signal input, no eff ect on control.
The following outputs are available:
• Global alarm, cumulative contact for all alarms and signals
• Serious alarm, cumulative contact of the alarms that stop the entire unit (with and without shutdown procedure)
• Minor alarm, cumulative contact of alarms that do not stop the unit and signals, e.g. fi lter alarm, maintenance alarm, tempe-
rature not reached.
