boards to incorrectly identify
themselves.

backup file. It may also occur if there
are inconsistencies in the reliability of a
setting in the backup file and on the
TEC device.
Cold air drafts are entering the back of
the TEC.
Air is being forced through the TEC
from a nearby vent.
The supervisory controller is not
communicating with the TEC. The TEC
is not mapped to a JCI Supervisory
System. The WNC Gateway is not
communicating with the TEC.
Lockout levels are used or the icons
are hidden due to the display settings.
