nvoEffDATempSP SNVT_temp_p Analog This network variable output communicates the effec-
tive discharge air temperature setpoint in degrees
Celsius to other devices. The valid range is from 0°C
to 70°C with a resolution of 0.01°C.
nvoEffDuctStatSP SNVT_press_p Analog This network variable output communicates the effec-
tive duct static pressure setpoint in Pascals to other
devices. The valid range is from 0 Pa to 1250 Pa with
a resolution of 1 Pa.
nvoEffectOccup SNVT_occupancy Enumerated The network variable output communicates the effec-
tive occupancy mode of the device.
nvoExhFanOnOff SNVT_switch Binary This network variable output communicates alarm
message information to other devices.
nvoExhFanStatus SNVT_switch Binary The network variable output communicates the
exhaust fan command (On/Off) of the device.
nvoFBDamper SNVT_lev_percent Analog The network variable output communicates face and
bypass damper status (0 to 100% open) of the device.
nvoHeatCool SNVT_hvac_mode Enumerated This network variable output communicates unit sta-
tus information to other devices.
nvoMATemp SNVT_temp_p Analog This network variable output communicates the
mixed-air temperature in degrees percent to other
devices. The valid range is from 0% to 100% with a
resolution of 0.005%.
nvoOADamper SNVT_lev_percent Analog The network variable output communicates outdoor
air damper status (0 to 100% open) of the device.
nvoOutdoorTemp SNVT_temp_p Analog This network variable output communicates the out-
door air temperature in degrees Celsius to other
devices. The valid range is from -40°C to 100°C with a
resolution of 0.01°C.
nvoSpaceCO2 SNVT_ppm Analog This network variable output communicates the
space CO2 concentrations in parts-per-million to
other devices. The valid range is from 0 ppm to 2000
ppm with a resolution of 1 ppm.
nvoSpaceRH SNVT_lev_percent Analog This network variable output communicates the
space temperature in percent to the device. The valid
range is from 0% to 100% with a resolution of 0.005%.
nvoSpaceTemp SNVT_temp_p Analog This network variable output communicates the
space relative humidity in degrees Celsius to other
devices. The valid range is from -15°C to 50°C with a
resolution of 0.01°C.
nvoUnitStatus SNVT_hvac_status (Structure) This network variable communicates unit status
information to other devices.
