User Roles and General Specification
The device parameters (data points) are structured and
made available to users in accordance with their user roles
(access levels). These roles must be assigned to the users by
the system administrator according to their expertise and
responsibility for device operation.
n Guest – allows only common parameters to be viewed.
User – allows common parameters to be viewed and
n
controlled, as well as start and stop of the device.
n Administrator – allows the system administrator to view
and control common and some special parameters, pre-set
operating parameters and modes for the user.
n Service – an access level recommended only for the sup-
plier or authorized service provider. In addition to the admin-
istrator's level, it allows the user to adjust highly specialised
configuration parameters related to the air-handling system
and its instrumentation, control constants, water heater
protection parameters, etc.

HMI to VCS System Access Default (factory) Settings
A control using the HMI controller uses an access right struc-
ture in accordance with the concept of structured access of
the air-handling device, refer to the chapter Overview and List
of Date Points, Factory Settings.
The HMI controller allows only four passwords (always four-
digit and numerical) to be set, each for a different access level.
Factory set default rights to access the VCS control unit using
the HMI controller:

Warning:
n When commissioning the device, we strongly recom-
mend changing the factory settings according to user
needs to maintain the safety of the device itself as well
as the controlled process.
n It is advisable to note and store the Service and Adminis-
trator passwords in a suitable (confidential) place (or up-
date them upon each change to settings) to have easy
access to them and thus maintain access to the system
at the Service and Administrator levels.
n If the Service password changed from the factory setting
is lost (forgotten), it is necessary to contact the man-
ufacturer's representative. The lost Administrator lev-
el password can be retrieved by the user of the Service
level (usually the supplier, installer or M&C service com-
pany).
n The changed password settings cannot be automatically
restored (reset, etc.) to the factory settings.
n The user of the SERVICE level can change the passwords
of all other user levels, the user of the ADMINISTRATOR
level can change the passwords of the GUEST and USER
levels while users of the USER or GUEST levels are not
allowed to change any passwords.
