NOTES:
1. A keyboard override cannot be performed during stagger up.
2. An external override can be done during stagger up, but the stagger up
sequence is still observed.
3. Status update will cancel a keyboard override or an external toggle over-
ride, but will not cancel an external timed override.
4. All programmed events have the same priority. The most recent event is the
one that is active.
As an example of hierarchy, consider a simple lighting control application. It is desired to turn
parking lot lights on at sunset and off at 11:00 PM. Programming an ON event at 1:00 PM,
an OFF event at 11:00 PM and using the astro feature will provide the desired control. The
ON and OFF events (at priority level 6) would energize the lights from 1:00 PM to 11:00 PM.
However, because the astro function has higher priority, the lights will be held off during day-
light hours, thus achieving the desired control.
