Haystack writable\npoints are modeled on the BACnet 16-level priority array with a\nrelinquish default which effectively acts as level 17.\n\nThe following levels have special behavior:\n - **Level 1**: highest priority reserved for emergency overrides\n - **Level 8**: manual override with ability to set timer to expire back to auto\n - **Default**: implicitly acts as level 17 for relinquish default\n\nThe priority array provides for contention resolution when many different\ncontrol applications may be vying for control of a given point. Low level\napplications like scheduling typically control levels 14, 15, or 16. Then\nusers can override at level 8. But a higher levels like 2 to 7 can be used\nto trump a user override (for example a demand response energy routine\nthat requires higher priority).\n\nThe actual value to write is resolved by starting at level 1 and working down\nto relinquish default to find the first non-null value. It is possible for\nall levels to be null, in which case the overall write output is null (which\nin turn may be auto/null to another system). Anytime a null value is written\nto a priority level, we say that level has been set to auto or released (this\nallows the next highest level to take command of the output).\n\nAlso see `docHaystack::Points#writable` chapter." ;
