In case of several active events, the area displays the event having higher priority of all the present events. The order of severity for the events displayed
in this area reflects the order in which the alarms are reported in the table, from the most to the least severe. The severity of the events is valued based on
the consequences they imply for the operation of the conditioning unit.
Area 3_A: Code of the event corresponding to the icon shown in area 3. As well as the code, the event type is also displayed (Signal or Alarm).
Area 4: "Cold" devices currently in operation
Compressor active
Split Type unit: At least one compressor of an MR
SLIM unit is active
NOTE
The flashing of the icon indicates that a request to switch on
the compressor has been received, but a safety countdown is in
progress (Split Type units: PAC-IF card time delays).
Area 6: "Humidity" devices currently in operation
Dehumidifier active
Humidifier active
When the icon flashes intermittently, the dehumidifier
activation request is in process, though a temperature block is
active (high or low temperature threshold, minimum temperature
threshold).
Instead, when the icon
activation request is in process, though a countdown is active for
compressor safety timing.
Area 8: Current unit ON/OFF status
This parameter can also be used to switch the unit on/off.
