Point Properties

Points may carry properties that qualify what the point represents. Each accepts a fixed set of values:

Property	Type	Applies To	Description
limit	min max	All points	Indicates whether the point represents the minimum or maximum limit.
mode	heating cooling warmup cooldown	All points	Specifies the operating mode the point is associated with.
modifier	alarm differential effective offset runtime static	All points	Additional modifier that describes this point.
schedule	occupied unoccupied standby	All points	Indicates which occupancy schedule the point applies to.

These distinguish points that share a semantic type. A zone temperature setpoint for occupied hours and one for unoccupied hours are both zone_air_temp_setpoint, separated by their schedule value. Likewise a heating setpoint and a cooling setpoint are separated by mode.

Each property also contributes a tag to the point’s ontology, so a point with schedule of occupied picks up the occ Haystack tag.

A value outside the accepted set is rejected.
