Repair Information
If the TEC3000 Series Thermostat Controller fails to operate within its specifications, replace the unit. For a
replacement thermostat controller, contact the nearest Johnson Controls representative.
Technical Specifications
The controller is unable to access a
USB drive.
The drive is formatted as NTFS or
another unsupported format. The TEC
supports FAT and FAT32 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 11 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.
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).
Some icons are hidden. Lockout levels are used or the icons
are hidden due to the display settings.
See Table 4 for lockout levels and
access details.

(LIT-12011034).
