Indicates the unit status. It combines the operating mode,
the capacity of heating and cooling, and any alarms that
are present in the object. The in_alarm status indicates the
highest priority current alarm identier.
Unit Status Fields
• mode: (see supported modes below)
• heat_output_primary: 0 to 100%
• heat_output_secondary: 0 to 100%
• cool_output: 0 to 100%
• econ_output: 0 to 100%
• fan_output: 0 to 100%
• in_alarm: (see alarm identiers below)
Supported Modes

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.
