nvoFcuStatus
normal operating modes, such as CTL_COOL. When the effective
occupancy changes to unoccupied or 24 hours have elapsed since
the last start-up or CTL_FLOATING_OUT_SYNCH mode, the
controller enters this mode again to reset the floating output
position tracking.
CTL_START_UP_WAIT is the first mode after an application
restart. No control algorithms are active, and heat/cool outputs stay
in their default positions. CTL_FLOATING_OUT_SYNCH follows.
CTL_DISABLED disables heat/cool control.
nvoFcuStatus alarm_type Same as nvoAlarm.type This output variable is the latest alarm detected by the node (if
any) and has the same value as nvoAlarm.type.
nvoFcuStatus dlc_shed Bit
NOT ACTICE
ACTIVE
0
1
This output variable indicates the state of the demand limit control.
nvoFcuStatus eff_window_open Bit
CLOSED or NOT_ASSIGNED
OPEN
0
1
This output variable indicates the real status of the window
detection, either from the digital input or from the network.
nvoFcuStatus hw_window_open Bit

1
This output variable indicates the status of the digital input
configured as a window contact.
nvoFcuStatus fan_feedback Bit

1
This output variable indicates the status of the fan when the digital
input is configured for an air flow sensor.
nvoFcuStatus external_active Bit

255
When the controller is configured for one or more fan stages, this
output variable reports the current fan stage active.
nvoFcuStatus output_position[0] SNVT_lev_percent
0 to 100%
163.835% = INVALID
This output variable indicates the position of the output 1.
nvoFcuStatus output_position[1] SNVT_lev_percent This output variable indicates the position of the output 2.
