Access Level description

Each board has a different Access Level (Par. 125); the user
interface inherits the access level from the virtual zone to
whom is associated.
Master Board always has access level 3, while for slave
boards access level is customizable.
The access level defines the operation that user can do
through the user interface.
Access Level 0: The user can only manage the own zone,
modify the setpoint and modify the mode between OFF
and the mode of Master, but he can't modify the schedule
and change the installation settings. It can be used for Slave
board installed in hotel rooms or when the user has to have
the lowest possibility to change the working parameters.

Output values

NOTE: if the output has positive configuration, output is
HIGH when the corresponding device has to be activated.
If the output has negative configuration, output is LOW
when corresponding device has to be activated.

Access Level 1: The user has the same limitation of Access
Level 0, but he can change the schedule. It can used for
installation where every zone of Slave board is used to
manage the comfort of a house or where the user can be
independent from the working operation of the other zone
of the same Slave board.
Access Level 2: The user can operate as per Access Level
1, but in addition, using the Zone key, he can connect to
-
virtual zone (other zone of the same slave board).
Access Level 3: The user can change the target address and
zone (Virtual zoning features are fully active). He can change
the master mode by connecting to virtual zone
as the local mode by operating on local zones.
Parameters in the variable table are grouped by access level.
All the descriptions are referred to positive configurations.
