This output variable indicates the position of the fan speed switch
ON the wall module.
nvoSensor remote_set_point SNVT_temp_p
-9 to 9 DDF (-5 to 5 K) for
relative
53.6 to 86°F (12 to 30°C) for
absolute
This output variable is the setpoint from the wall module setpoint
knob and may be absolute or relative depending upon
nciWallMod.set_pnt_knob.
nvoSensor space_temp SNVT_temp_p
0 to 104°F (0 to 40°C)
621.806°F (327.67°C) =

This output variable is the measured space temperature.

This output variable is used to establish hardware-dependent
factory default configuration settings for the Fan Coil Unit
controller. Note that D and F versions and E, G and J versions
differ only in their supply voltage.

OC_NUL
(at application restart)
This output variable shows the state of the locally-wired occupancy
sensor, if one is configured by nciFcuConfig.DI1_config. OC_NUL
means no input is available because it is not bound or not
configured by nciFcuConfig.DI1_config.
nvoSpaceTemp SNVT_temp_p
0 to 104°F (0 to 40°C)
621.806°F (327.67°C) =
INVALID
INVALID
(at application restart)
This output variable is the sensed space temperature at the node
taken from the locally-wired sensor. It is typically bound to
nviSpaceTemp of another node which may not have its own space
temperature sensor but controls the same space. It is also used for
monitoring purposes, showing the current space temperature used
for the control algorithm. nvoSpaceTemp is transmitted
immediately when its value has changed significantly (> 0.5
delta°C). The reported space temperature includes the offset
correction nciWallMod.si_space_temp_zero_cal. If a space
temperature sensor is not connected or is shorted or if
