Technical specifications
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).
For wireless models, Supervisory
Status = Offline
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.
1. Map the TEC into a JCI Supervisory system.
2. Verify that the PAN’s WNC Gateway is online.
3. Add ZFR Pro Routers/Repeaters into the
wireless system.
Some icons are hidden. Lockout levels are used or the
icons are hidden due to the
display settings.
See Table 6 for lockout levels and access details.
The touchscreen is unresponsive. You tap the display or touch the
controller within 5 mm of the
display when power is applied to
the controller.
Reboot the controller. Do not interact with the
controller until the home screen displays.
You do not tap the touchscreen, but
the display acts as if it is tapped,
which causes the display to blink or
toggle between screens.
You need to tap the display at an
offset from a touch point to activate
the display.
