SG Connect - Occupancy modes
This feature can be configured to maximize lighting control behavior together with wireless switches. The mode options are auto-on/auto-off, manual-on/manual-off and manual-on/auto-off.
Auto on/Auto off
Lights are switched on and off automatically based on occupancy detection and timer settings. This is the default operating mode for the sensor. In this automatic behavior, lights always switch on to Eco on level. For more details, see Figure 1, Figure 2 , and Figure 3.
Manual on/Auto off
Lights are turned on with a manual command from a wireless switch. A manual on command switches on the lights to Eco-on level and can be further tuned up to Task Level. Lights turn off automatically once vacancy is detected, and timers expire. This mode is typically selected to achieve maximum energy savings. For more details, see Figure 4.
Manual on/Manual off
Lights are turned on and off manually through a wireless switch. This is typically used in applications which just need wireless manual control for switch on/off or dimming functionality. This setting must be selected for a MasterConnect System consisting of Xitanium Wireless Drivers only.
Figure 1:
Auto-on / Auto-off mode
Figure 1 shows the occupancy cycle during automatic light behavior with Eco-on Level set lower than Field Task Level. On occupancy detection, lights switch on to Eco on level. Once vacancy is detected, Hold time starts. During Hold time, lights remain at Eco on level and then dim down to Background light level, with a configurable Grace Fading time. Lights remain at this dim level until Prolong Time expires; after which lights switch off.
Figure 2:
Auto-on / Auto-off with Daylight Dimming
Figure 2 shows how daylight dimming takes place during Auto on/Auto off mode. Once occupancy is not detected anymore, the timers (Hold time and Prolong time) start. Once the timers expire, lights switch off.
Figure 3:
Auto-on / Auto-off with Manual Override
Figure 3 shows how daylight dimming takes place during Auto on/Auto off mode and the effect of manual overrides.
In case of manual override with a switch, lights can be dimmed up or down between the Task Level and Minimum dimming level. When no occupancy is detected anymore, the timers (Hold Time and Prolong Time) get started.
In case occupancy is re-detected during Hold time, the existing light behavior continues, and the timers are reset.
In case occupancy is re-detected during Prolong Time (or after), automatic light behavior starts, and the timers are reset (as shown).
Figure 4:
Manual On / Auto Off
Figure 4 shows how daylight dimming takes place during Manual on/Auto off mode. Occupancy detection starts to determine the light behavior soon after manual trigger.
