START_UP_WAIT X Mode: The result of the controller determining which mode of operation it
currently is in. At each power-up, the controller remains in the Start-Up and
Wait mode (a random time from 0 to 20 minutes that is based on the units
network number). After that period, the mode changes to initialize actuators
that will fully close the damper and valve actuators to insure full travel when
under program control. The various other modes are due to normal
operation as well as manual and network commands.

OC_NUL X EffectOcc: Result of controller supervising the various Occupied controlling
inputs and deciding which one to use. See StatusinOcy, DestSchedOcc,
ManualOcc and StatusOvrd.

OC_NUL X DestSchedOcc: DestSchedOcc is calculated from OccTimeClock and
nviTodEvent.CurrentState using the following logic: If
nviTodEvent.CurrentState is OC_OCCUPIED and OccTimeClock is
ST_NUL, then DestSchedOcc is OC_OCCUPIED. If
nviTodEvent.CurrentState is OC_UNOCCUPIED and OccTimeClock is
ST_NUL, then DestSchedOcc is OC_UNOCCUPIED. If
nviTodEvent.CurrentState is OC_STANDBY and OccTimeClock is
ST_NUL, then DestSchedOcc is OC_STANDBY. If
nviTodEvent.CurrentState is don’t care and OccTimeClock is ST_ON, then
DestSchedOcc is OC_OCCUPIED. If nviTodEvent.CurrentState is don’t
care and OccTimeClock is ST_OFF, then DestSchedOcc is
OC_UNOCCUPIED. OC_OCCUPIED means the space is scheduled to be
occupied. OC_UNOCCUPIED means the space is scheduled to be
unoccupied. OC_STANDBY means the space is scheduled to be in a
standby state somewhere between OC_OCCUPIED and
OC_UNOCCUPIED.

ST_NUL X OccTimeClock: OccTimeClock shows the state of the physical time clock
input via nvoIO.OccTimeClock ORed with nviTimeClk. Valid enumerated
values are: ST_OFF means OC_UNOCCUPIED when either the time clock
input is configured and nvoIO.OccTimeClock is 0 and nviTimeClk is not
SW_ON or nviTimeClk.state is SW_OFF and nvoIO.OccTImeClock is not 1.
ST_ON means OC_OCCUPIED when either the time clock input is
configured and nvoIO.OccTimeClock is 1 or nviTimeClk.state is SW_ON.
ST_NUL means that the local time clock input is not configured by
nciIoSelect and nviTimeClk.state is SW_NUL. There is no time clock
configured or bound to the node.
