The iQ display has the ability to display all the faults
associated with your extraction unit. The image below
shows an example of some of the fault icons that may
appear in the alarm window of the LCD display.
Visual Alarms on the iQ system
The iQ system can visually display a wide range of alarms on
its LCD panel. The visual displays, meanings and solutions
are detailed below. All alarms will trigger the system alarm
interface output signal and the inbuilt audible buzzer, if
fitted/ activated.
Over Temperature Alarm
If the iQ system detects an internal temperature greater
o
than 60 C then it will automatically shut down the extractor
to prevent damage to components within the extractor.
Once the internal temperature has dropped by 5
extraction unit will be able to restart.
To restart the extractor after an over temperature alarm the
unit needs to be placed in Standby mode then powered on
again.

Hose blocked alarm
The iQ system features a 2 stage Hose blocked alarm.
 Partial hose blockage
 Full hose blockage
Partial hose blocked alarm
This alarm will become active when the iQ system detects a
part blockage in the installation. The iQ system interprets a
partial blockage as a vacuum spike within the ductwork but
is only a partial blockage as the extractor is still able to
maintain its set airflow.
During this time it is normal to hear the motor increase in
speed. The blockage will need to remain in the ductwork for
over 5 seconds before the alarm is given.
Full hose blockage
This alarm will become active when the iQ system detects a
full blockage in the installation. The iQ system interprets a
full blockage as a vacuum spike within the ductwork and is
considered a full blocked as the extractor cannot maintain
the set airflow with the blockage present.
During this time it is normal to hear the motor increase in
speed. The blockage will need to remain in the ductwork for
over 5 seconds before the alarm is given.
0
C the To remove the blockage, isolate the extraction unit from the
mains, remove the flexible hose, locate and remove the
blockage then reattach the hose as previously installed.
