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 (NV) index number is a unique identifier for certain L
reference these variables. The NV index number can also be found in the XIF file.
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 offline).
