MMI user guide
5.1
Push Button Menu:
Pushing the button on a device provides the user with several possibilities.
A single short push has a specific meaning for the given device, for this sensor a single short push will toggle the
occupancy status (occupied/unoccupied.). Pushing the button for longer (push, hold for a few seconds, and
release) allows the user to set the device into a desired mode. A mode change happens at 5 second interval.
Below, these modes are illustrated in a state chart.
When cycling through the menu modes, the state is indicated by a number of 100ms blinks on the LED. As
illustrated in the figure, the menu system allows for device specific modes (e.g. Pair Devices for Devices such as
relays and occupancy sensors).
5.2
Action upon Push Button Release
The number of blinks associated with a given mode entry is shown in the below table along with the associated
action performed upon user button release. As indicated, if the user holds the button past the Reset to Factory
Fresh Settings no action will result from the push button and the device stays in the idle state.
