The TEC3000 zone temperature
does not change fast enough
compared to the measured zone
temperature from a verification
device (a calibrated sensor).
The TEC3000 is configured by
default for larger spaces with
normal-sized equipment when a
proportional device is active.
Select Control Setup >Tuning > Equipment Size
> Oversized.
The zone space temperature
increases or decreases too much
when the unit is active in
unoccupied mode.
The heating and cooling
equipment are too big for the
unoccupied space.
Decrease the Unoccupied Off Delay parameter
from 10 minutes to a more appropriate time for the
equipment configuration.
The controller provides an error
when trying to back up settings.
The USB drive is defective. Try a different USB drive.
The controller provides an error
when trying to restore settings from
a backup.
The USB drive is defective. Try a different USB drive.
The Restore file is corrupt. Try restoring a different backup file.
The Restore file is from an
incompatible model TEC.
Ensure that the backup file being restored was
from the same model TEC.
The controller is unable to access a
USB drive.
The drive is formatted as NTFS
or another unsupported format.
The TEC supports FAT (for
networked models), FAT16 (for
wireless models), and FAT32
(for all models) formats only.
Reformat the USB drive, or try a different USB
drive with a supported format.
The USB drive is defective. Try a different USB drive.
The controller displays Board
Mismatch.
The I/O board that the display
board is currently attached to
does not match the one that
initially shipped with the display
board.
Attach the display board to the correct I/O board.
A hardware failure is causing the
two boards to incorrectly identify
themselves.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
The controller displays Controller
Fault.
An internal fault was detected
and the controller was unable to
recover.
Order replacement units and return the affected
devices to Johnson Controls under the RMA
program.
The Bell icon is displayed on the
TEC home page.
The fault has been detected on
the TEC.
See Table 7 for TEC fault causes and resolution.
Partial Restore Complete is
displayed when trying to restore
settings from a backup file.
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.
1. Create a Backup file on a USB drive for the
TEC that is showing the issue.
2. Edit the backup file created in the previous
step on a PC to reflect the desired settings.
3. Verify that the modified values are within
minimum and maximum range in the backup
file.
4. Restore the settings from the newly edited
backup file on the TEC.
The temperature displayed is lower
than the actual room temperature.
Cold air drafts are entering the
back of the TEC.
Seal any holes behind the TEC to reduce drafts.
Air is being forced through the
TEC from a nearby vent.
Move the location of the TEC or change the
venting to prevent air from being forced through
the TEC.
For networked models, the
Online icon does not appear for a
networked controller.
There is improper field bus
wiring.
Refer to the MS/TP Communications Bus
Technical Bulletin (LIT-12011034).
