START_UP_WAIT

currently is in. At each power-up, the controller remains in the Start-Up and

COOL

2

Wait mode (a random time from 0 to 20 minutes that is based on the units

OFF_MODE

3

network number). After that period, the mode changes to initialize actuators

DISABLED_MODE

that will fully close the damper and valve actuators to insure full travel when

DestSchedOcc: DestSchedOcc is calculated from OccTimeClock and

OC_UNOCCUPIED

1

nviTodEvent.CurrentState using the following logic: If

OC_BYPASS

2

nviTodEvent.CurrentState is OC_OCCUPIED and OccTimeClock is

OC_STANDBY

3

ST_NUL, then DestSchedOcc is OC_OCCUPIED. If

OC_NUL

255

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.

OccTimeClock: OccTimeClock shows the state of the physical time clock

input via nvoIO.OccTimeClock ORed with nviTimeClk. Valid enumerated

ST_MED

2

values are: ST_OFF means OC_UNOCCUPIED when either the time clock

input is configured and nvoIO.OccTimeClock is 0 and nviTimeClk is not

ST_ON

4

SW_ON or nviTimeClk.state is SW_OFF and nvoIO.OccTImeClock is not 1.

ST_NUL

255

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.
