nviSpaceTemp is bound to another node, nvoSpaceTemp is not
reported on the network.
This output variable belongs to the Node Object and reports the
status for any object on a node. This is the answer to the
nviRequest.
This output variable indicates whether nviRequest uses a fault
object ID.
This output variable indicates whether nviRequest uses a fault
request.
This output variable indicates whether the device is enabled or
disabled (nviManualMode = DISABLE).
This output variable indicates whether an update nviRcvHrtBt is
missing.
This output variable indicates whether an alarm occured. See
nvoAlarm.
This output variable shows the answer to nviRequest >
REPORT_MASK
This output variable shows the terminal load, which is a percentage
between -160% and +160% based upon the control output level.
Negative values indicate heating load and positive values indicate
cooling load. 100% is the full terminal capacity. An absolute
terminal load value of more than 100% indicate that the terminal is
not able to supply the required heating or cooling energy which at
the zone controller should cause a demand for more supply
energy. nvoHeatOutput will be transmitted immediately when its
value has changed significantly (>= 1%).
This output variable reports the last operating mode of the control
algorithm. It is not set to HVAC_OFF if the Heating and Cooling
Output shows 0%. HVAC_OFF is set when the Device is disabled
from nviRequest, nviManualMode or nviApplicMode.
