Appendix: Database Operations
With enteliZONE thermostats, we can use either the System Loader or Flash Loader
utilities to load the version 3 firmware. System Loader can upgrade multiple devices
at a time. With the enteliWEB 4.14 BACnet front end, you can now use the Manage
Device Firmware utility.
The enteliZONE thermostats are version 3 firmware and the Manage Device
Firmware utility in enteliWEB version 4.14 can handle this firmware.
Load Database
With the enteliWEB 4.14 BACnet front end, you can use the Manage Device Firmware
utility.
When you use System Loader or Flash Loader to upgrade an enteliZONE thermostat,
use OWS340.3946 (340R4) or higher.
If you use Flash Loader, you can log in over Ethernet but you must have a device
such as a system controller to route over UDP/IP to the eZNT-Wi/ eZNTW.
System Loader can log into an enteliZONE thermostat directly over UDP/IP.
When you upgrade firmware using System Loader or Flash Loader, make sure that
AP mode is off as BACnet data transfer is extremely slow if AP mode is on. It is
recommended to avoid any BACnet operations while AP mode is on.
Clear Database
This explains how to clear the database in an enteliZONE thermostat and also how
to return a thermostat to the default factory state.
Clear Database Using ORCAview/ enteliWEB
1. Ensure that the database is backed up as Clear deletes the current database
and replace it with the default database.
2. If you use the Clear Database command from ORCAview/ enteliWEB, the
objects in the database are put to default. However the network settings are
retained and are NOT cleared.
