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 identier 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 ofine).
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.
