OC_OCCUPIED

0

OC_NUL

X

NetManOcc: NetManOcc reports the network manual occupancy state from

(nvoCtlDataG1)

OC_UNOCCUPIED

1

nviManOcc. The valid enumerated states are: OC_OCCUPIED indicates

OC_BYPASS

2

occupied OC_UNOCCUPIED indicates not occupied OC_BYPASS

OC_STANDBY

3

indicates that the space is bypass occupied for

OC_NUL

255

nciAux2SetPt.uiBypassTime seconds after nviManOcc is first set to

OC_BYPASS OC_STANDBY indicates that the space is standby. OC_NUL

means that no manual override is active.

SenOcc

OC_OCCUPIED

0

OC_NUL

X

SenOcc: SenOcc indicates the current state of the sensed occupancy and

(nvoCtlDataG1)

OC_UNOCCUPIED

1

is calculated from nviSensorOcc and the local occupancy sensor via

OC_BYPASS

2

nvoIO.OccupancySensor. The local sensor and nviSensorOcc are ORed

OC_STANDBY

3

together. If either the local sensor or nviSensorOcc shows occupancy, then

OC_NUL

255

SenOcc shows occupancy. The valid enumerated values are:

OC_OCCUPIED means that occupancy is sensed by one or more

sensor.OC_UNOCCUPIED means that no occupancy is sensed by any

sensors.OC_NUL means no local sensor is configured and nviSensorOcc

has failed to be received periodically (bound or not bound).

EconEnable

ST_OFF

0

ST_NUL

X

EconEnable: EconEnable indicates the current suitability of outdoor air for

(nvoCtlDataG1)

ST_LOW

1

use in cooling used by the control process EconEnable is periodically

85

ST_MED

2

calculated either from the sensor(s) specified by nciConfig.EconEnable or

ST_HIGH

3

from nviEcon. When nviEcon.state is not SW_NUL, then the local inputs

ST_ON

4

are ignored and nviEcon.state is used instead. See nciConfig.EconEnable.

ST_NUL

255

The valid enumerated values are: ST_OFF means the outdoor air is not

suitable to augment cooling. ST_ON means the outdoor air is suitable to

augment cooling.ST_NUL means no local sensor is selected by

nciConfig.EconEnable, or the selected local sensor has failed or has not

been configured by nciIoSelect, and that nviEcon.state is SW_NUL. The

outdoor air is considered unsuitable for cooling.

ProofAirFlow: ProofAirFlow indicates the current state of the ProofAirFlow

(nvoCtlDataG1)

ST_LOW

1

switch used by the control process and is read by the local sensor via

ST_MED

2

nvoIO.ProofAirFlow. The valid enumerated values are: ST_OFF means air

ST_HIGH

siCalcODEnthalpyS7

btu/lb

SI_INVALID

X

siCalcODEnthalpyS7: siCalcODEnthalpyS7 is the calculated outdoor air

(nvoCtlDataG1)

0 to 100

enthalpy in btu / lb calculated from the siOutdoorTempS7 and

ubOutdoorHumidityS1. siCalcODEnthalpyS7 is used to determine the

suitability of outside air for cooling when nciConfig.EconEnable is

SINGLE_ENTH and both outdoor temperature and humidity sensors are

present. siCalcODEnthalpyS7 is compared to the enthalpy setpoint stored

in nciAux1SetPts.ubOdEnthalpyEnableS2.

SI_INVALID

X

siCalcRAEnthalpyS7: siCalcRAEnthalpyS7 is the calculated return air

(nvoCtlDataG1)

0 to 100

enthalpy in btu / lb calculated from the siReturnTempS7 and

ubReturnHumidityS1. siCalcRAEnthalpyS7 is used to determine the

suitability of outside air for cooling when nciConfig.EconEnable is

DIFF_ENTH and both outdoor and return (or space) temperature sensors

74-

and humidity sensors are present. Sensors may be physically connected to

the node or available over the network.
