Probable causes
The I/O board that the display
board is currently attached to
does not match the one that
initially shipped with the display
board.
A hardware failure is causing the
two boards to incorrectly identify
themselves.
An internal fault was detected
and the controller was unable to
recover.
The fault has been detected on
the TEC.
Not all of the items in the backup
file have been restored. This
error can be caused by a value
being out of the minimum or
maximum range in the 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.
There is improper field bus
wiring.
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.
You tap the display or touch the
controller within 5 mm of the
display when power is applied to
the controller.
