Return an enteliZONE thermostat to Default Factory State Using
RUN/CLEAR Jumper
The eZNS/eZNT/eZNT-Wi/eZNTW-WI+eZNTW products all have a Run/Clear
jumper that provides a way to restore all objects to factory default and remove any
network settings. Any network configuration information is also cleared.
For the eZNT-Wi and eZNTW-Wi, dual mode is the default behavior on a new device
or after a reset to the factory default database using the RUN/CLEAR jumper.
To clear the database to factory default using the RUN / CLEAR Jumper:
Ensure that the database is backed up before you do this procedure.
1. Remove power from the device.
2. Remove the frontplate from the backplate.
3. Put the RUN / CLEAR jumper into the Clear position.
4. Put the frontplate back on the backplate.
5. Apply power. You need to apply power to clear the database to factory default.
6. Wait for the display to show Clr and flash with a red color.
7. Remove power from the device when 'done' displays on the screen.
8. Remove the frontplate and put the RUN / CLEAR jumper into the Run position.
9. Replace the frontplate.
10. Power the unit on. The device operates normally and shows the startup
information for the thermostat when it is powered up.
If the Run/Clear jumper is left in the Clear position and power is applied, the
unit will NOT start up. The display indicates this condition by showing Clr and
flashing a red color on the front display. The Jumper must be in the Run
position for the device to start up.
