MonitorSens nvoCtlDataG2 siMonitor1S10 volts
1 to 10
SI_INVALID X siMonitor1S10: siMonitor1S10 is the voltage applied at the monitor input
terminals. If the sensor is not configured or has failed, the value is
SI_INVALID.
CoolPos nvoCtlDataG2 sbCoolPosS0 Percentage
0 to 100
0 X sbCoolPosS0: If the node is configured for modulating cool, sbCoolPosS0
shows the current position of the cooling modulating output.
HeatPos nvoCtlDataG2 sbHeatPosS0 Percentage
0 to 100
0 X sbHeatPosS0: If the node is configured for modulating heat, sbHeatPosS0
shows the current position of the heating modulating output.
EconPos nvoCtlDataG2 sbEconPosS0 Percentage
0 to 100
0 X sbEconPosS0: If the node is configured for modulating economizer,
sbEconPosS0 shows the current position of the economizer modulating
output.

TRUE
0
1
FALSE X For SpaceTempError, a value of 1 (TRUE) indicates that data was not
available from the sensor and will result in a SENSOR_FAILURE alarm. A
value of 0 (FALSE) indicates a normal condition. The heating and cooling
control loops will be turned off it there is a space temp sensor failure. The
fan will remain under normal control.

FALSE For SetPtError, see preceding. Upon a failure of the local setpoint, the
control loop will use the default occupied setpoints to control space
temperature.
