8.2.9.4 Manual Control
To control the sunblind manually the L-DALI sunblind controller offers the possibilities to
directly select a setpoint and to select a scene.
Direct Control
The sunblind can be controlled manually by the following network variable inputs of type
SNVT_setting:
 nviLocalControl: Using this input network variable a local control devices can
provide the setpoint for the sunblind.
 nviGroupControl: Using this input network variable a control device which
controls a group of sunblinds can provide the setpoint for the sunblind.
 nviGlobalControl: Using this input network variable a control device which
controls all sunblinds can provide the setpoint for the sunblind.
Per default nviLocalControl takes precedence over nviGroupControl which in turn takes
precedence over nviGlobalControl. The priorities can be changes as described in Section
8.2.9.9. Local, group, and global control commands can be cancelled by setting the
.function field of the corresponding network variable to SET_NUL.
Scenes
Using the input network variable nviSBScene of type SNVT_scene up to 16 sunblind scenes
can be saved and recalled. The command SC_LEARN stores the current sunblind position
and rotation in the specified scene number. By a SC_RECALL command previously stored
scenes can be recalled. Scenes can be deleted by a SC_RESET command.
8.2.9.5 Prioritized Control
The L-DALI sunblind controller offers two methods for prioritized control: maintenance
mode and override mode. Maintenance mode has the highest priority and cannot be
changed. The priority of override mode can be changed as described in Section 8.2.9.9.
Maintenance Mode
There are two alternative ways to control the sunblind in maintenance mode:
 nviSetMaint: This input network variable of type SNVT_setting overrides the
sunblind output. The maintenance mode override is canceled by setting the
.function field to SET_NULL.
 nviMaintenance, nciMaintValue: The nviMaintenance network variable of type
SNVT_switch can be used to switch on/off maintenance mode. If the maintenance
mode is active, the sunblind output is set to the value of the configuration property
nciMaintValue (type SNVT_setting).
Override Mode
There are two alternative ways to control the sunblind in override mode:
 nviSetOverride: This input network variable of type SNVT_setting overrides the
sunblind output. The override is canceled by setting the .function field to
SET_NULL.
