Structure Bind to this network variable input to communicate
heating occupied, occupied-standby, and unoccupied
setpoint shifts; and cooling occupied, occupied-
standby, and unoccupied setpoint shifts in degrees
Celsius to the device. The valid range is from -10°C
nviSourceTemp SNVT_temp_p Analog Bind to this network variable input to communicate
the water-loop temperature in degrees Celsius to the
device. The valid range is from 0°C to 100°C with a res-
olution of 0.01°C.
nviSpaceRH SNVT_lev_percent Analog Bind to this network variable input to communicates
the space relative humidity in degrees percent to other
devices. The valid range is from 0% to 100% with a
resolution of 0.005%.
nviSpaceTemp SNVT_temp_p Analog Bind to this network variable input to communicate
the space temperature in degrees Celsius to the
device. The valid range is from -15°C to 50°C with a
resolution of 0.01°C.
nviValveOverride SNVT_hvac_overid (Structure) Bind to this network variable input to communicate
water valve overrides to the device.

Variable name SNVT Data type Description
nvoAlarmMessage SNVT_str_asc Analog This network variable output communicates alarm
message information to other devices.
nvoDischAirTemp SNVT_temp_p Analog This network variable output communicates the dis-
charge 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.
nvoEffectOccup SNVT_occupancy Enumerated The network variable output communicates the effec-
tive occupancy mode of the device.
nvoEffectSetpt SNVT_temp_p Analog This network variable output communicates the effec-
tive space temperature setpoint in degrees Celsius to
other devices. The valid range is from -5.6°C to 56.1°C
with a resolution of 0.01°C.
nvoEnterWa-
terTmp
SNVT_temp_p Analog This network variable output communicates the effec-
tive entering water temperature in degrees Celsius to
other devices. The valid range is from --40°C to 100°C
with a resolution of 0.01°C.
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 status
information to other devices.
nvoMixedAirTemp 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 res-
olution of 0.005%.
