HeatStgsOn

nvoData1

HeatStagesOn

0 to 4

0

X

HeatStagesOn: HeatStagesOn indicates how many heating stages are on.

(nvoCtlDataG1)

If the node is controlling a heat pump, HeatStagesOn indicates how many

auxiliary heating stages are turned on.

CoolStgsOn

nvoData1

CoolStagesOn

0 to 4

0

X

CoolStagesOn: CoolStagesOn indicates how many compressor stages are

(nvoCtlDataG1)

on. If the node is controlling a heat pump, compressor stages are turned on

for both heating or cooling.

Free1Stat

nvoData1

Free1Out

FALSE

0

FALSE

X

Free1Out: Free1Out indicates the state of FREE1_OUT digital output. 1

(nvoCtlDataG1)

TRUE

1

means on, and 0 means off.

Free2Stat

nvoData1

Free2Out

FALSE

0

FALSE

X

Free2Out: Free2Out indicates the state of FREE2_OUT digital output. 1

(nvoCtlDataG1)

TRUE

1

means on, and 0 means off.

OccStatOut

nvoData1

OccStatusOut

FALSE

0

FALSE

X

OccStatusOut: OccStatusOut indicates the state of the

(nvoCtlDataG1)

TRUE

1

OCCUPANCY_STATUS_OUT digital output. 1 means on (not

OC_UNOCCUPIED), and 0 means off (OC_UNOCCUPIED).

SaFan

nvoData1

FanOn

FALSE

0

FALSE

X

FanOn: FanOn indicates the state of the FAN_OUT digital output. 1 means

(nvoCtlDataG1)

TRUE

1

on, and 0 means off.

StatusEconOut

nvoData1

AuxEconOut

FALSE

0

FALSE

X

AuxEconOut: AuxEconOut indicates the state of the AUX_ECON_OUT

(nvoCtlDataG1)

TRUE

1

digital output. 1 means that the packaged economizer is enabled, and 0

means the economizer is disabled. A packaged economizer is always

treated as the first stage of cooling when an economizer is configured by

nciIoSelect.

nvoData1

EconFloatSynch

FALSE

0

FALSE

EconFloatSynch: EconFloatSynch indicates that the economizer damper

(nvoCtlDataG1)

TRUE

1

motor is being synchronized with the reported economizer position by

driving the damper for a period longer than it takes to fully close the

damper. The reported economizer position is synchronized whenever an

endpoint is reached (full open or full close).and when the elapsed time

since the last synchronization is 24 hours.

DlcShed

nvoData1

DlcShed

FALSE

0

FALSE

DlcShed: DlcShed indicates the state of nviDlcShed. When DlcShed is 1,

(nvoCtlDataG1)

TRUE

1

demand limit control set by an energy management node is active. If the

effective occupancy is OC_OCCUPIED or OC_STANDBY when demand

limit control is active, then the setpoint is shifted by

nciAux1SetPt.siDlcBumpTempS7 in the energy saving direction. When

DlcShed is 0, demand limit control is inactive. If nviDlcShed fails to be

received periodically or nviDlcShed becomes 0, then the setpoint is ramped

back to the original setpoint over a 30 minute interval.
