The reference setpoint used to determine the Effective
Heating/Cooling setpoints. It is the value of the local,
hardwired space temperature setpoint. It is only valid if the
unit controller JP5 conguration jumper is congured for Long
Range Setpoint Adjust and is enabled by nciLocSptEnable.

The value of the hardwired space temperature sensor
installed either in the return air or in the space. Writing to
Space Temp Input (nviSpaceTemp) does not affect Local
Space Temp (nvoLocalSpaceTmp) but does affect Effective
Space Temp (nvoSpaceTemp).

1. Analog Null (0x7FFF) is a discrete temperature value of 621.806ºF/327.67ºC. Its purpose is to indicate a sensor failure condition or when the unit controller is not
using that temperature value.
2. The Network Variable index number is a unique identier for certain LonWorks variables. Some BAS companies use this numeric value instead of text to
reference these variables. The NV index number can also be found in the XIF le.
3. After Receive Heartbeat is enabled, this variable reverts to the default (non-override) value if it is not refreshed often enough through a network command or if
communication is disabled (i.e. the device is disabled or is ofine).
4. The totalizer continues to increment until the maximum count is reached, at which point the BAS must reset the value by issuing a write command. The variable is
saved in nonvolatile memory every 24 hours. If power is lost, that day’s totalizer information is not stored.
