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 override, 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 park-
ing 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 daylight hours, thus achieving
the desired control.
