When Automatic Setback is enabled, light fixtures in the Setback Group automatically transition to the configured Setback Level after an area has been unoccupied for the duration of the Setback Timeout.
Below is an overview of how automatic active, inactive, and setback levels work:
When a node detects occupancy, it goes to its active brightness level (blue). When it no longer detects occupancy, the active/inactive timeout timer starts. After that time has elapsed, the node goes to its inactive brightness level (white).
Active/Inactive timeouts occur at the node level, so once each node no longer detects occupancy for the timeout period, it individually moves to its inactive brightness level (white).
Once all nodes within a group do not experience occupancy for the length of the setback timeout, they all move into the setback brightness level (grey). The setback is active for that entire group.
If all of a group is in setback, but one node becomes activated, that single node moves to the active brightness level, but the rest of the nodes remain at the setback active level.
Once a second node in that group becomes active, it also moves to the active brightness level, and the remainder of the lights in that group all move to the Inactive brightness level (i.e they move out of setback). The default threshold for moving groups out of setback is two nodes.
Example
In this example, a Group has the Task Tune settings set to the following:
- Active Level: 100%
- Inactive Level: 20%
- Timeout: 1 minute
And the Setback settings have been set to the following:
- Setback Level: 0%
- Setback Timeout: 30 minutes
Behavior
If all fixtures in the Setback Group do not detect occupancy for 30 minutes, the Group moves to their Setback level of 0%. When occupants return to the area beneath those fixtures, the Setback Group transitions from their Setback Level to their Task Tune settings.
