4.6.4 Controller configuration: password protected access by
user roles
The controller configuration can be backed up and/or restored. The handling is
safe and flexible:
● The controller configuration can be accessed by different user roles.
● The controller/plant configuration can be password-protected for each of these
user roles.
● An Administrator can set the password in ABT Go or ABT Site.
● Users can backup/restore their
own
configuration file.
The controller has 3 default users (see table below). A total of 6 users are possible.
Example of allowed operations by different user roles.

4.6.5 Factory Reset
A Special BIN file can reset the controller to Siemens factory default settings
(including a password reset).
You must request the BIN file.
The controller must be reset to factory settings on site.
Download the BIN file, for example, via ABT Go and set input DI1 to 1 (for example
via a closed contact). Once completed, the controller starts the factory reset and
restarts automatically.
Note
: This BIN file does not include normal HRV functions, it can only be used for
the factory reset.
