Acknowledgment procedure for a class A or B alarm
Class A or B alarms require manual acknowledgement via the HMI in order to return the unit to normal operation.
The procedure for manually acknowledging an alarm (class A or B) consists, from the Active Alarms menu, of recording the alarm by
selecting the "record" option for the alarm in question. This alarm can be in the following states:
-
Active: the fault is currently present, the manual acknowledgement (recording) will not allow the machine to be restarted
until the fault is corrected. This is the case, for example, for the triggering of the overheating safety thermostat of the
electric heating coil (BE)
-
Returned: the fault has disappeared (or been resolved) and has therefore been cancelled (is no longer present). Recording
this will allow the machine to be restarted. It will reappear if the problem persists.
When an active alarm is cancelled, blocked, or acknowledged, this change of status is recorded in the faults history, which makes it
possible to know exactly when faults appear/disappear, thus facilitating the diagnostic procedure.

Acknowledgment of the filter alarm
Minimum access level:
Service
An alarm appears every 12 months (not settable) to indicate the need for a service visit. Enter YES to reset the counter and
acknowledge the alarm.
Counting is only done when the power is on, even if the fans are off. Counting is not operational when the unit is off, 6 months = 6 x
30 days = 180 days.
This alarm can be deactivated via the menu configuration alarms/alarm 86 and set to priority "not active" instead of "Alarm-C".
XX.10.
Presence of active alarms
The presence of active alarms is indicated by the flashing of the red LED on the HMI of the unit.
Pressing the red button on the HMI allows direct access to the active alarms menu if at least one active alarm is currently present. If
there are several alarms present at the same time, the last one is displayed by default, and it is possible to display them one after
the other by successively pressing the up or down arrow.
Access to the active alarms menu does not require an access level.
