Boole an FALS E TRUE de couple s the pres e nt-value prope rty from the
physical output. While TRUE, the pres e nt-value can be
change d to any value to s imulate conditions for tes ting
without affe cting the actual phys ical output.
present-value

Enumerated INACTIVE Eithe r ACTIVE or INACTIVE. Note that a NULL value
can be written to the pre s e nt-value on data dis plays , but
the value is actually written to a priority-array prope rty.
The pre s e nt-value is the re s ult of the priority array.
minimum-on-time

Real 60 Enable s you to s e t anti-cycle limits for a BO in seconds.
This is carrie d out through priority-array inde x 6. For
e xample , by writing a value of 60 to the minimum-on-
time property of a BO, you s e t a minimum ON time of 60
se conds.
minimum-off-time

Real 60 Enable s you to s e t anti-cycle limits for a BO in seconds.
This is carrie d out through priority-array inde x 6. For
e xample , by writing a value of 60 to the minimum-off-
time prope rty of a BO, you s e t a minimum OFF time of
60 s e conds .
priority-array BACne t
PriorityArray
<Array of
BACne t
P rio rityVa lue >
A read-only array of prioritize d value s (1-16) controlling
the pre s e nt-value , priority 1 having the highe s t priority.
The value with the highest priority controls the pre se nt-
value . Poss ible values for priority-array inde xe s are
ACTIVE, INACTIVE, or NULL. A NULL value indicate s
no command is iss ue d at that priority le ve l.
