Air shut o zone
Why shut o the air ow?
In properties housing several dierent businesses that utilise
their premises at dierent times for example, it may be prefer-
able to be able to shut o parts of the system at certain times,
when the premises are not being used.
How does shut o of the zone damper
work?
The air ow in a zone damper can be shut o with a mode
called Air o for a desired time via SuperWISE, Modbus or
BACnet. The position of the damper is then set to 0%. Zone
damper can also be set to Air o via Schedule.
When zone dampers are closed, all underlying rooms are also
shut o automatically, and similarly all comfort alarms are
blocked. When Air o is enabled for the zone, the room temper-
ature in underlying rooms is then controlled according to No
occupancy mode and comfort alarms are blocked.
When closing supply air dampers on zone level, it is important
to note how the extract air is congured and where applicable,
shut o the extract air damper if appropriate.
Note, in order for automatic functions in the event of a shut o to
work, it is important that the installation is congured correctly
and thus describes the structure set for the air ow in the format
Air handling unit-Zone damper-Room-Room damper.
When shutting o a large number of zone dampers, the easiest
way to perform this is in Quick settings.
Shutting o the air handling unit
When a connected GOLD air handling unit is shut o, WISE will
automatically detect this and prevent alarms from being set in
the room. The damper will be set in ‘default mode’ to facilitate
the restart of the air handling unit. If the air handling unit is of
the type Generic AHU, the Modbus parameter for ‘AHU Running’
should be used to obtain equivalent functionality.
