OC_NUL X NetManOcc: NetManOcc reports the network manual occupancy state from
nviManOcc. The valid enumerated states are: OC_OCCUPIED indicates
occupied OC_UNOCCUPIED indicates not occupied OC_BYPASS
indicates that the space is bypass occupied for
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.

OC_NUL X SenOcc: SenOcc indicates the current state of the sensed occupancy and
is calculated from nviSensorOcc and the local occupancy sensor via
nvoIO.OccupancySensor. The local sensor and nviSensorOcc are ORed
together. If either the local sensor or nviSensorOcc shows occupancy, then
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).

ST_NUL X EconEnable: EconEnable indicates the current suitability of outdoor air for
use in cooling used by the control process EconEnable is periodically
calculated either from the sensor(s) specified by nciConfig.EconEnable or
from nviEcon. When nviEcon.state is not SW_NUL, then the local inputs
are ignored and nviEcon.state is used instead. See nciConfig.EconEnable.
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.

ST_NUL X ProofAirFlow: ProofAirFlow indicates the current state of the ProofAirFlow
switch used by the control process and is read by the local sensor via
nvoIO.ProofAirFlow. The valid enumerated values are: ST_OFF means air
flow is not detected. ST_ON means air flow is detected. ST_NUL means no
air flow switch is configured.

SI_INVALID X siCalcODEnthalpyS7: siCalcODEnthalpyS7 is the calculated outdoor air
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
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
and humidity sensors are present. Sensors may be physically connected to
the node or available over the network.
