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 computer to
reflect the preferred 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 supervisory controller is not
communicating with the TEC. The TEC
