TEC3000 Series On/Off or Floating Fan Coil and Individual Zone Thermostat Controllers with Dehumidification

Capability Installation Instructions

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 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.

For common MS/TP troubleshooting information, refer to the

MS/TP Communications Bus Technical Bulletin

(LIT-12011034).
