EXCEL 10 FCU CONTROLLER LNS PLUG-INS USER GUIDE
default
0 (at application restart)
This input variable is used to control the reheat relay via the
network. This permits use of the relay as an auxiliary output in
applications where reheat is not required as well master/slave
applications where the reheat output is controlled by another
controller acting as master.
OFF (at application restart)
See above.
This input variable belongs to the Node Object and provides the
mechanism to request a particular mode for a particular object
within a node.
See above. Commanding any modes other the ones listed will
result in an "invalid_request" when reading nvoStatus.
OC_NUL
This input variable allows an occupancy sensor of another Excel
(if bound but fails to be
10 controller to be used to indicate the sensed occupancy state of
received or at application
the space. OC_NUL means no input is available because it is not
restart)
bound, bound but not received periodically, or not configured by
nciFcuConfig.DI1_config. More than one occupancy sensor may
be bound to nviSensorOcc. If any one sensor detects occupancy,
the controller considers the space occupied.
INVALID
This input variable is used for binding third party nodes to
(at application restart)
authorize them for setpoint modifications. When this has been
bound and a valid update is received, the local configured set-
points will no longer be directly used to determine the current
occupancy setpoint. For OCCUPIED and STANDBY modes, this
is used with the appropriate ZEB (derived from the configured
setpoints), for UNOCCUPIED mode the setpoint does not depend
upon this input, but upon nciTempSetPts.unoccupied_cool/_heat
only. nviSetpoint is stored in RAM and gets lost after power
failure. In this case, the setpoints of nciTempSetPts will be used
until a valid nviSetpoint is received.
