— Lighting

Limiting artificial lighting to the necessary intensity and to the conditions in which it is actually needed can have an important impact on electricity consumption, especially in the tertiary sector where consumption related to it is more important.

The main automation functions that can lead to a reduction in consumption by acting on lighting in contexts sometimes residential sometimes different are: • Switching on and off of lighting fixtures with all types of lamps manually (with traditional push-buttons or remote controls) or automatically (by means of timers or presence or twilight sensors). • Switching on of the marker lamps and/or localization LEDs integrated in the push-buttons and control units connected to the twilight sensor. • Automatic switching on and off according to movement (in passage areas) or the presence of people. • Command and control of even very large groups of luminaires • (zones/floors/whole building). • Automatic control of external luminaires, luminous signs and shop window lighting with twilight logic. • Temporary disconnection of non-priority luminaire groups.

• Adjustment of light intensity by means of electronic devices to increase or decrease the illuminance of the rooms by acting on traditional buttons of various kinds (two-position rocker switches, traditional, etc.) or by using twilight or brightness sensors. • Automatic adjustment to constant brightness with maximum use of natural lighting and integration of the artificial component only if actually necessary. • Programmed alternation between different groups of luminaires to optimize the life of the sources. • Possibility of counting the operating hours of the luminaires with optimization of preventive and routine maintenance. • Replication of the control points (single and group) wherever there is bus wiring. • Local (push-button) or centralized (on synoptic, Touch-Screen or PC with visualization) status signaling of individual or group luminaires.
