Additional Operating Modes
and Function Settings
Additional operating modes and functions can be activated
in the List of Data Points in the section Settings – Additional
Operating Modes, Functions. Once the respective mode or
function has been set, it is necessary to perform SW reset
using a specific data point 211 (Reset after the configuration
of additional modes/functions).

User Settings Backup and Recovery
It is advisable to perform backups especially before significant
changes in control parameter settings (PID controller fac-
tors, temperature setting for compensations or starting of
the optional additional modes), or always when the control
works optimally. Data backup or recovery can be performed
using the HMI controller in the List of Data Points, section
Checks – User Settings.

List of Data Points, Factory Settings
Warning:
The device parameters are structured and made available to
users in accordance with their user roles (access levels). These
roles must be assigned to users by the system administrator
according to their expertise and responsibility for device opera-
tion. Access to the data points is also limited by the user role
level – for levels lower than Service, not all parameters (data
points) are displayed, respectively, they can be read without
being able to change (save) them. The Parameter List with a
combination of all possible air-handling unit applications is in-
cluded in the List of data points under the highest access right.
